Webflow file upload form
Add a file upload form to your Webflow site without paying for Webflow's file storage. Use an Embed element with the markup, and the file posts as multipart form data straight to Formpaste. No backend.
How to build it
- Create a form in your Formpaste dashboard and copy its access key.
- Connect Storage in the dashboard so the form can accept uploads.
- Add an Embed element with the markup above and your access key, then publish.
Webflow gotchas
Webflow's native form is real, but the free plan caps you at a handful of submissions and file uploads need a paid tier. You have two clean options with Formpaste: repoint the native form's action URL, or drop an Embed element with your own markup for things Webflow cannot do natively, like multi-step or file upload.
Repoint the action URL, or use an Embed
For a standard form, set the form's action to the Formpaste endpoint and add a hidden access_key field. For full control - multi-step, file upload, custom fields - use an HTML Embed element with the generated markup instead.
Beat the submission cap
Webflow's free plan limits form submissions. Posting to Formpaste removes that cap - submissions land in your Formpaste inbox regardless of your Webflow plan.
File uploads without a paid tier
Webflow gates file uploads behind a paid plan. An Embed that posts multipart form data to Formpaste accepts uploads with no Webflow upgrade, and your site never handles the file.
Keep the access_key in the markup
Whether you repoint the action or use an Embed, the hidden access_key input must be present so Formpaste knows which form received the submission.
What to get right
A file means multipart, not urlencoded
As soon as the form has a file input, it must post multipart form data. The generated code sets enctype and sends the raw FormData, so the file rides along with the other fields. No upload endpoint of your own is needed.
The upload is client to Formpaste, direct
The browser posts the file straight to Formpaste, so your app never buffers or parses the upload. That sidesteps serverless body-size and runtime limits entirely.
Set expectations on size and type
Tell people what you accept. File uploads are a Pro feature; connect Storage in the dashboard first, and keep the input honest about accepted types and size.
How it works
Three simple steps for form submissions to land in your email inbox.
Create your form, set your form's action URL to Formpaste's endpoint, and add your access key.
