How to Enable File Upload on Product Pages in PrestaShop (Step-by-Step Tutorial)

In 2025 and the coming years, personalised products will be driving ecommerce growth. Whether that’s custom prints, custom engraved gifts, branded merchandise and apparel, or input-from-your-customer products, your potential customers will love to shop customized goods.

As a Prestashop store owner, you can enable this option to allow customers to add files on the product page, immediately before adding them to the cart. This is really helpful when you need logos, images, PDFs, design notes, or any other files that your client needs to send as part of an order.

To use these features, you have to rely on an innovative file upload module that we will discuss thoroughly in this blog post, along with the advantages of allowing such uploads. So without further ado, let’s get started.

What is the Benefit of Allowing File Upload on Product Pages?

Allowing customers to upload files on your PrestaShop product pages isn’t just convenient; it’s necessary for any store that accepts customized or made-to-order products. 

Your customers can add Images, logos, Documents, and Design files while ordering, and you will get everything in one place, on your product page.

Common Business Use Cases

Companies that enable product personalization frequently have a need for file uploads as well, such as:

• Print-on-demand (t-shirt printing, mugs, phone cases) stores
• Photo services (canvas prints, posters, albums)
• Personalized item shops (engraving, embroidery, plaques)
• Corporate merchandise suppliers (logo branding)
• Service-based transactions (document uploads, scans of IDs

Key Benefits

• Increased automation: Files come with the order, and workflow is a breeze.
• This is for the customer's convenience: there is no need to contact support, and the user can upload all in one place.
• Reduced volume of support: Less back and forth in email, fewer missing files.
• Increased conversions: The easier the personalisation, the happier your buyer’s journey.

PrestaShop comes with built-in customizations (extensible with modules), and you can quickly set up a seamless PrestaShop product customization area that’s all about supporting different file types, validation rules, and instructions personalised to the user.

Prerequisites for Enabling File Upload

Before you go and start allowing customer file uploads (cluster 3), make sure your environment is prepared for them. Here’s what to look for:

Required Permissions

You need:

• Admin access to your Back Office
• Permission to edit products
• The correct hosting permissions are required to receive the file uploads
• Ensure your server allows to allow users to upload files without restrictions.

PHP File Upload Limits

If you have large uploads, your hosting will need to support big files. Check these PHP settings:

• Upload max filesize
• Post max size
• Max execution time

Customers can experience errors if upload max file size is too low (2MB, for example).

Once your environment is set up, you’re good to go.

How to Add a File Upload Field to Product Pages

Let’s look into how to enable a file upload on the PrestaShop product page using its native Customisation tab.

Step 1: Log in to Your PrestaShop Admin Panel

• Begin by logging into the backend of your store.
• Enter your email and password.

Once inside, navigate to:

Catalog → Products

This is the place where you control all of your listings. You will be given an overview of all existing products, as well as options to edit, duplicate, or create new ones. You will find the customization options you need on each product’s editing page.

Step 2: Select the Product to Edit or Create a New One

Decide whether you'd like to add file upload functionality to your existing product or develop a new one from scratch!

To Modify An Existing Product: Select Edit from the corresponding product row.

New Product: Click the New Product in the top-right corner.

Inside the product editor, you will notice a few tabs: Basic settings, Quantities, Shipping, SEO, and Combinations, the one we’re interested in for this tutorial: Customization.

There, you will set up your file upload field.

Step 3: Open Up Customization. Finally, you need to enable customization.

On the left panel of the product editor, navigate to Customizations.

You will see two main fields:

• File fields
• Text fields

To activate the upload feature:

• Set File fields to 1 or more (whatever the number of uploads you'd like).
• Every line equals one upload box on a product page.

For Example:

1 File field → Customer uploads one file

3 File fields → Customer can upload up to three files

Underneath each field, you can include a Label. This is what shoppers will encounter, so include simple instructions like:

• "Upload your logo."
• "Submit your image."
• "Upload your file (PNG, JPG, PDF)."
• "Please upload the file necessary for the order."

It is useful for UX and SEO because the placeholder text can be seen on the PrestaShop product page file upload section.

Step 4: Setting Up File Uploads Configurations

The provided customization tool may be basic, but you do get a few key settings.

Allowed File Types

Common file types are accepted out of the box, but what’s allowed is dependent upon your server configuration. The most common formats include:

Images: JPG, PNG, GIF

Documents: PDF, DOCX

Vector/Design source files: SVG, AI, EPS(Requires some module or server setup)

If you are restricting file types for security or workflow reasons, include that in the label.

Number of Uploads

If the product needs more than one upload (for example: front and back), then create 2 file fields and give them a name.

Validation Settings (Optional via Module)

If you have a dedicated file upload module, you can set:

• Maximum file size
• File type restrictions
• Image dimension limits
• Required vs optional uploads
• Preview thumbnails

Real-time validation messages

This improves usability and security.

Step 5: See if you can upload the file in the back office and in the front office as well.

• Make sure to test the upload process as a customer before going live.
• Visit the Front Office (your live shop).
• Navigate to the product page where you added customisation.
• You will now find the upload fields under the “Product customization” section.
• Attempt to upload various types and sizes of files.

Add the product to the cart and check that the uploaded file is listed in the cart summary, checkout, and order detail.

This is to make sure that your PrestaShop front office file upload works properly before customers use it.

Step 6: If There Are Issues

If something goes wrong, try these easy fixes for common complaints.

Issue: No upload field on product page

• Did you set File fields > 0?
• Is the product saved?

Is there any product customization available with the theme? Some themes require an update.

Problem:  “File too large” error

Increase your server limits:

• Upload max file size
• Post max size
• You should set both to 10M or more if you expect big images.

Problem: Permission denied

• Check the folder permissions:
• /upload and /download folders should be writable (usually 755 or 775).

Problem: Wrong file type

Specify accepted formats in the field label.

Pro Tips For A Better File Uploader

Once you’ve activated the basic upload feature, you can improve usability and increase conversion rates even more with regard to customers’ interaction with the upload fields.

Ways to Improve UX & Personalisation

• Add Tooltips or Descriptions
• Under each field, add a short meaning or tip:
• “Maximum size: 5 MB”
• “Upload PNG or JPG only.”
• “For best print results, use at 300 DPI.”

This reduces customer frustration and eliminates incorrect submissions.

Enable File Preview (Via Module)

If you would like to show an uploaded image on the image before the cart, you will need a module that provides an option for displaying the image. This increases confidence and decreases order errors.

Upload Text & File Together

Allow customers to upload a file and write more info:

Uploaded logo

• Text field: “Add engraving message.”
• This makes a full-blown personalized journey.

Mention Security + Quality

It’s a rule of thumb that all uploaded files will be validated server-side, especially for formats like SVG, ZIP, or PDF.

When to use a design module of PrestaShop File Upload 

PrestaShop’s native customisation is great for basic usage, but it also has its limitations. When you have advanced personalisation needs, you may want to upgrade to a module.

When a Module Becomes Essential

Use a module if you need:

• Several uploaded files per product or quantity
• File previews before checkout
• Uploads on cart or checkout page(s)
• Conditionally upload (eg, based on product variants)
• Advanced validation (dimensions, size, formats)
• Drag-and-drop upload interface

Better Integration with The Order Workflow

In our PrestaShop File Upload Module, customers can upload files on product, cart & order pages with an easy-to-validate and interactive UI.

Conclusion

One of the best ways to do this is to let your shoppers upload files on your product pages. PrestaShop allows you to add fields with standard variables, set labels, and let your customers share the files for you to complete their order. Add file fields or select pre-existing ones from the predefined ones. Allow it only in the given categories.

Once you configure it, the process is seamless for you and your customers, with lower errors, clearer communication, and higher conversions for personalised products.
