Three questions that decide this

1. Where should the customer upload? On the product page, so the file is tied to that item, or at checkout, so it is one file for the whole order. Print and personalisation nearly always want the product page. Document collection usually wants checkout.
2. Do you need to control what gets uploaded? Accepting any file of any size from the public is a real risk, not a theoretical one, and the tools differ sharply here.
3. Do you need to look at the file before you produce the order? If a wrong file costs you a print run, you want to approve it, not just receive it.

What WooCommerce gives you on its own

Nothing. There is no file upload field in core, on the product page or at checkout, and the block checkout's Additional Checkout Fields API supports only text, select, checkbox and date. There is no free, no-plugin route to this one.

That makes the comparison simpler than most: the question is which plugin, not whether you need one.

Where the upload appears

Every line below comes from the vendor's own listing or documentation, read on 5 October 2026.

Most plugins in this category do one end or the other. A plugin built for the product page will not collect a file at checkout, and a checkout upload cannot be attached to one specific line item, which matters the moment a customer orders two personalised products in one go.

File types and sizes: the part worth caring about

An upload field open to the public, with no restriction on what can be sent, is one of the easier ways to get a WordPress site into trouble. At minimum you want to choose which extensions are accepted and cap the size.

The Woo row deserves a word of care, because it is the official extension and it carries more than 100,000 installs. Its own documentation does not discuss type or size restriction either way. Multiple reviewers on its listing state that neither can be limited. We have reported that as what it is, a consistent claim from reviewers rather than a vendor statement, and if you are evaluating it the right move is to ask Woo support directly before you buy.

Whatever you choose, remember your server has the final word. An upload larger than your hosting's upload_max_filesize or post_max_size fails regardless of what the plugin allows, usually with no useful error.

Pricing, approval and rules

The approval column is the real divide. Everything here receives files. If you print, engrave, embroider or fabricate, receiving is the easy half: what costs money is discovering after production that the artwork was 72 dpi, the wrong size, or the customer's holiday photo. Being able to look at a file, reject it with a note, and have the customer told automatically is a different job from storing an attachment.

Price and size

Choosing between them

You need one file at checkout and have no budget. Checkout Files Upload's free version handles a single file, with type and size limits, and can show the field only when certain products are in the cart. That is a complete answer for document collection.

You need a simple product page upload and have no budget. Product File Upload is free, limits extensions and sizes, and can be enabled per product. It is small, at around 600 installs, so weigh that.

You already use Product Add-Ons for other customisation. Adding a second plugin for uploads is reasonable if you need type and size control, since those two things are what reviewers say it lacks.

You run a print, engraving, embroidery or signage business. This is the case the free tools do not cover. You want the file tied to the line item, a charge for the upload, a size and type gate before the file ever reaches you, and a way to reject bad artwork with a note before it goes to production. Customer Upload Files for WooCommerce is built for that, and it is ours.

Customers often buy before their file is ready. Look for uploads after the order, so you keep the sale and collect the artwork while the order is still pending.

Questions to ask before you buy

1. Can I restrict file types and sizes? Ask explicitly rather than assuming. This is the single biggest difference between these tools and it is a security question, not a convenience one.
2. Where are files stored, and can they be reached by URL? A file in an unprotected uploads folder is public to anyone with the link, whether or not you intended that.
3. Is the upload attached to the line item or to the order? It matters the moment someone orders two personalised products at once.
4. Can a required upload actually be enforced? On product pages this depends on your theme. A theme that adds items by AJAX can skip validation, so test it on your own site with a real theme.
5. Does it work on the block checkout? Several listings in this category say nothing either way, and two of them are checkout tools.
