How to Let Customers Upload Files on Product, Cart & Order Pages

When you allow customers to upload files, you actually offer them personalisation. They can upload files directly attached to their product, cart, checkout & order, like images, artwork, PDFs, design briefs, medical or legal documents, a warranty form, even a rhyming poem with a funny picture for granny, etc. This serves as a great way to get the customised output they need. 

By 2025, file uploads will automate intricate processes and distinguish stores for most e-commerce stores. For instance, print-on-demand stores collect custom artwork for a t-shirt/mug/poster/label via file upload fields.

Without an integrated upload system, Prestashop stores are forced to use email exchanges, making the fulfilment process suboptimal and error-prone, resulting in unhappy merchants and customers. A trustworthy file upload module for PrestaShop can eliminate these bottlenecks by allowing users to easily & securely upload files directly from the shopping cart.

Speaking of which, this interesting blog post focuses on how merchants can make use of the file upload module to let their customers interact with their stores better. So without further ado, let’s get started. 

Where Can You Allow Customer File Uploads?

Using an innovative module like the FME’s file upload, you can choose exactly where your customers should send their files. Every page has a different goal, and supports a difference flow or can be a total shift in the experience.

Here’s a look at the different locations you can consider allowing a file upload from potential customers:

Product Page Uploads

Best for:  customisation, print on demand, engraving, custom manufacturing, and art uploads.

The direct upload on the product page transmits a signal to your customers that their file is associated with the product. This is perfect if the upload is required before “Add to cart”.

Pros:

• Personal items with the highest conversion rate.
• Prevents incomplete orders.
• Enables customers to preview file requirements.

Cons:

• Not suitable for complex multi-product projects.
• Not good for orders that don’t need files after product selection.

Checkout Page Uploads

Best for: when industries require last-minute documents (warranty forms, compliance files, legal docs).

File upload on checkout PrestaShop makes sense in case the latter is not a personalisation but something you need for verifying the order.

Pros:

Minimises friction during browsing

Super for B2B compliance or ID proofing.

Cons:

Check out how upload failure can hinder conversion.

Order Detail / My Account Uploads

Best for: customer file upload PrestaShop is good for post-purchase documentation, corrections, additional requirements, and warranty claims.

With the Prestashop product page file upload (Cluster 1) module, customers can upload files after purchase, excellent for custom designs and customer support.

Pros:

• Useful for projects and revisions.
• Great for warranty or service issues

Cons:

Not ideal if you require the files before payment

How to Set Up the Module: Step-by-Step

Installing the secure file upload PrestaShop module (Cluster 2) in PrestaShop takes a maximum of 10 minutes. Here is a full tutorial: Installation, File limitations, Required Rules, Cloud Integration, and Testing.

Install the Module

• Go to the fmemodules.com and purchase, plus download the Prestashop upload file module.  
• Sign in to your PrestaShop Back Office.
• Go to Modules → Module Manager → upload file prestashop module and browse for the downloaded file.
• Drag the ZIP here or click to select manually.
• Click Install and run the installation process until a dialogue displays, indicating that it is complete.

After you install it, a number of new configuration pages can be found under Modules → File Upload (or similar) in the web UI.

Configure Allowed File Types

Now you have to determine what kind of file formats are allowed for upload by users.

• Supported popular formats: Prestashop upload PDF, JPG, PNG, SVG, ZIP, DOCX, AI, PSD and XLSX.
• Open the module configuration.
• From the Allowed extensions, specify which file types to allow.
• Provide a tooltip or reminder for customers (“We accept PDF, JPG, PNG).

Tip:

If you are providing print-on-demand or graphic design services, be sure to offer AI, EPS, SVG, etc. or even compressed ZIP files.

Manage File Size & Limits

• Have a global file size limit (20-50 MB, depending on your server).
• Define per-file and per-order limits.
• You can also turn on big file mode for Google Drive/Dropbox if you want.

Enable Upload Locations

You can activate uploads on:

• Product page
• Cart page
• Checkout
• Order Detail

My Account

Just switch each location on and add custom text to labels such as “Upload your design” or “Attach documents.”

• Enable Cloud Uploads (For Google Drive / Dropbox).
• Go to Cloud Integrations in module settings.
• Link your Google Drive or Dropbox account.
• Set the folder where to upload.
• Decide on the local or cloud location, or both, for files.
• Cloud Uploads work great for large design files (50–500MB).

Set Mandatory Upload Rules

For products that require personalisation:

Enable Mandatory upload.

Decide whether to apply the rule against:

• Product page (pre-Add to Cart)

Cart

• Checkout
• Include validation messages (“You forgot to upload your artwork”).
• Configure Customer Group Rules

Also, you can allow uploads for only specific groups (e.g., B2B customers).

Now, let’s go to Customer Groups in the module.

• Select which groups can upload.
• Save changes.
• Test the Upload Flow

Always test from the front office:

• Add a product to the cart.
• Try uploading multiple file formats.
• Test required rules and error messages.
• Make a test purchase, and check that the uploads appear in the admin.

Security & Compliance: Best Practices

Things can get tricky for store owners when they’re dealing with personal documents, large media files or sensitive business information. That’s what the customer file upload PrestaShop use cases (Cluster 3) tell. The ideal PrestaShop upload module should adhere to a rigid set of security norms and ensure the safety of both customers and shop owners. 

Here are the key best practices to make the most of the PrestaShop file upload module features in 2025.

Strict File Type Validation

Only white list file types are needed (e.g, PDF, JPG, PNG, zip). Never use “allow all.”

Do not use formats that can execute, such as exe, php, js or sh, for industries that are high-risk (legal, medical and financial).

Max File Size & Server Limits

Set a decent hard limit based on your workflow.

Typical safe ranges:

• Regular product uploads: 5–20 MB
• Print on Demand Files: 50–200MB

Virus & Malware Scanning (Recommended)

PrestaShop will not natively support antivirus scanning, but you can combine third-party scanners like:

• Clam server-side scanning
• Scanning from Cloud storage through Google Drive APIs
• Hosting providers’ malware filters

File scanning should be enabled for sure on stores where hundreds of uploads are coming in.

• Security Storage Alternatives (Local + Cloud)
• You save each in their restricted (755 or tighter) folders.
• Cloud storage options, Google Drive and Dropbox, here add redundancy and protect against server load.

GDPR & Data Handling Compliance

In the case that customers should upload their pictures, IDs, or personal documents:

• Include a privacy notice next to the upload box
• Keep files around only as long as necessary
• Use SSL/HTTPS for all transfers
• Give users the ability to remove their files

Permission Restrictions

To prevent PrestaShop file upload (cluster 4) error, limit uploaded files in the admin area.

Only the users with appropriate permissions should see and download customer documents.

Admin Workflow: Manage, Preview, Attach & Download Files

From the moment your customers begin uploading files, the admin side workflow becomes critical to ensure speed, accuracy, and high levels of customer satisfaction. 

Designed with the latest technologies, this impressive module’s file management system serves to streamline the process of previewing, attaching, or downloading files without ever having to leave the back office!

Centralised File Management

Uploaded files are listed in an admin panel by product, order, or customer!

Administrators are able to sort and search through files by date, file type or even order status, making it very easy for admins of sites that have hundreds, if not thousands, of uploads a day.

Preview Files

The module also integrates into the file browser and allows you to preview common file types directly in your browser:

• Images: JPG, PNG, SVG
• Documents: PDF, DOCX, XLSX
• Compressed archives: ZIP

This avoids unnecessary downloads and speeds up verification.

Attach Files to Orders

Admins have the ability to attach uploaded files in a particular order so that all order-related documents stay in the same place. This is especially useful for:

• Custom product proofs
• Legal or compliance documents
• Warranty claims
• Bulk Actions
• Delete multiple files at once
• Change the name of a file or move it to another folder
• Export file lists for reporting or printing. 

Notifications & Alerts

Get regular email alerts on the new uploads. This makes sure that the processing does not get delayed and no file is left out.

Audit & Compliance

Timestamp, identity of the uploader, and association with an order are recorded for all loaded files, which can be used to keep track of regulatory requirements and internal quality control.

Integrations and Advanced Features

Contemporary PrestaShop file-upload add-ons are designed for more than simple file management; they provide neat solutions and enhanced capabilities to facilitate work, automate order processing, and render services that exceed customer expectations.

Cloud Storage Integrations

Google Drive & Dropbox: Enable clients to upload their files directly from their cloud storage, perfect for large design jobs or numerous project items.

Files are savable to specified folders automatically, so you can minimise the use of server storage and manage your files better.

PDF Templates & Document Automation

Make use of uploaded files with PDF layout for invoices, certificates or individual printed matter.

Merge customer uploads with templates on-fly for easy production flows.

Order-Processing Automation

• Combine with print shop or other external production software.
• Automate notifications or output files straight into production systems.
• Supports batch export, which can accelerate processing for orders.

Developer Hooks & Custom Fields

Further extend the module and adapt it to specific business needs using PrestaShop hooks.

Add custom metadata or associate uploads with specific order details fields.

These features are particularly valuable to print-on-demand stores, B2B customers and advanced order workflows, allowing merchants to scale their business without losing accuracy or security.

Pricing, Compatibility & Support

The PrestaShop file upload module is on the official Addons store, and it works with quite a lot of versions, from v1 to. 7 through v9. This guarantees compatibility with old and new setups.

There are three different licenses (single-store, multi-store, and extended support), and the cost will differ. Prices often include some of the following:

Lifetime Updates

• Access to cloud integration features

Support & Updates:

• The developers update it frequently for bug fixes and to ensure compatibility with more recent versions of PrestaShop.
• Technical support covering assistance for installation, configuration, and any other product-related problems is included.
• Fast setup is possible thanks to documentation and video tutorials.
• This makes it an excellent choice for any merchants who need a feature-rich, supported, and future-proof solution for customer file uploads.

Real-World Examples & Case Studies

PrestaShop file-upload modules are used in various industries that serve to automate the processes, enhance customer satisfaction, and offer customisation of the products. Here are some examples of how the methods can be applied, along with case studies:

Custom Apparel & Print-On-Demand

In this T-shirt printing shop, users can upload their art right on the product page. This eliminates back and forth via email, maintains your printed files are produced to your specs, and minimizes the risk of errors in ordering. 

Customers can upload in more formats (such as JPG, PNG, or PDF) and also see the design before they check out, leading to higher satisfaction and repeat purchases.

Photo Printing & Personalised Gifts

Mugs, canvas prints, and photo books can be made from high-resolution images online at photo-print stores. Clients can submit big files smoothly through cloud integrations(Google Drive/Dropbox). The admin has the ability to view uploads or attach them to an order and even send proofs to production partners automatically.

Certificates & Legal Documents

A B2B training marketplace, where learners can upload their certificates or identification documents. The purchaser is prompted to upload documents at checkout, which the admin verifies and then issues certificates. This creates compliance, minimises manual manipulation, and preserves audit logs. Hence, PrestaShop file upload can improve the customer experience (cluster 5). 

B2B & Custom Orders

Manufacturers enable customers to upload CAD files, logos and specifications. Backhauled uploads can be done at the cart page or order detail page for mass submissions. The files are attached by admins to orders, communicated with production teams, and notifications are automated.

Examples like this one show how, regardless of industry, whether we’re in an eCommerce retail setting or working with professional services clients, file uploads can save time, minimise mistakes and ultimately provide a better experience for the customer.

Conclusion

PrestaShop file upload by customers is not a luxury feature anymore; it’s a must-have for the stores that provide personalisation, B2B services, or document-based processes. By allowing uploads on product, cart, or checkout pages (or even directly at the time of purchase), you can speed up your business and gain more shares through increased customer experience. 

With secure handling, cloud integrations, and a flexible admin workflow, this module will enable your store to process complicated orders with ease, stay compliant, and always be easy for your shoppers to use.
