Add multipart encoding to the form
Set enctype="multipart/form-data" on the <form> tag. Without it, the browser submits the text fields but silently leaves the selected file out of the request.
File upload form
File upload form for any website, no backend.

Yes — SplitForms forms can accept file uploads. Add enctype="multipart/form-data" and a file input, connect Storage, and visitors can attach resumes, PDFs, screenshots or images straight from your HTML form. Paid plans store up to 5 files of 5 MB each; no upload server, SDK or S3 signing flow is needed.
- 5 files per submission
- No upload server
- Signed download links
Standard HTML file input
A normal multipart form post to one endpoint — no JavaScript SDK, no client-side S3 signing and no separate upload server.
Private storage, signed links
Files are stored privately and shared through expiring download links, with executables and script-like files blocked.
Up to 5 files at 5 MB
Attach resumes, briefs, screenshots or PDFs per submission. Text fields still arrive if a file is rejected.
Copy-paste ready
A complete file upload form, add your access key.
Set the access key from your dashboard, keep the multipart encoding, and connect Storage before testing. Without Storage, the text fields still submit but the files are not retained.

How to add a file upload form to your website.
Six steps from markup to a stored file. The only file-specific change is the multipart encoding and the file input; the access key, spam fields and notifications work the same as any SplitForms form.
Add a named file input
Use <input type="file" name="resume">. Add multiple to allow several files, accept to guide the file picker, and required to make an attachment mandatory. The name is the field the backend reads.
Create a free access key
Sign up with email and password — no credit card. The access key appears in the dashboard and goes in the hidden access_key field.
Connect Storage in the dashboard
Open Dashboard → Integrations → Storage and connect it. This is the step that makes SplitForms retain uploaded files; it is available on the paid plans.
Publish and send a test upload
Paste the form into your site, submit a real file, and confirm the submission, the file link and the notification email all arrive. Text fields still submit if a file exceeds plan limits.
Route or copy the files onward
Download files from the dashboard, receive small uploads as email attachments, include file metadata in webhook payloads, or connect Google Drive to copy every upload into a folder you own.
Security
Are file uploads secure?
Uploads are stored privately rather than in a public bucket, and the dashboard exposes them through expiring signed links. SplitForms blocks executable and script-like extensions and sniffs the content type on the server. The HTML accept attribute only filters the file picker — it is not a security boundary. For larger intake, read the file upload feature and limits.
- Private object storage, not a public file bucket
- Signed download links with a 7-day window
- Executable and script-like extensions rejected
- Content type sniffed server-side
Plan requirement
Which plan do you need for file uploads?
Retained uploads need a paid plan and the Storage integration connected in the dashboard. Pro is $5 per month with 500 MB of storage; Annual is $49 per year with 5 GB. On the Free plan the text fields and notification still work, but attached files are dropped. Compare the details on SplitForms pricing.
- Pro: $5 per month, 500 MB storage
- Annual: $49 per year, 5 GB storage
- Free: text fields saved, files dropped
- Limits: 5 files at 5 MB each
Use cases
What can people upload?
The same form works for a job application with a resume, a support request with screenshots, a design brief with a PDF, or a client intake with reference images. For a closer starting point, copy the contact form with file upload template and adapt its fields.
- Resumes and job applications (PDF, DOCX)
- Screenshots and photo attachments for support
- Design briefs, RFPs and reference images
- Client intake documents and signed forms
How SplitForms works
What happens after someone submits your form?
splitforms receives the submission, filters spam, saves it to your dashboard and emails you — then, on paid plans, sends it on to your webhooks and integrations. No backend infrastructure to build.
Add your endpoint
Point your form to your unique SplitForms endpoint. That's it.
Receive submissions
We instantly capture and organize every submission in your inbox.
Route anywhere
Send data to email, spreadsheets, CRMs, webhooks, and 7,000+ apps.
No credit card required. Set up in under 60 seconds.
Connect & automate
Where can submissions go besides email?
On paid plans, submissions can also go to Slack, Discord, Google Sheets, Notion, Airtable, Zapier or any signed webhook — and splitforms works on the platforms you build on, from WordPress and Shopify to Next.js. With Stripe connected, your forms can take payments too.

File upload form questions.
View all FAQsCan SplitForms forms accept file uploads?
Yes. Add enctype="multipart/form-data" and a named <input type="file"> to any HTML form that posts to the SplitForms endpoint. With the Storage integration connected on a paid plan, SplitForms stores the upload privately and shows it in the dashboard with a signed download link. The current limit is 5 files per submission at 5 MB each.
Which plan do I need for file uploads?
Retained file uploads require a paid plan plus the Storage integration: Pro is $5 per month with 500 MB of storage, and Annual is $49 per year with 5 GB. On the Free plan, text fields are saved normally but attached files are dropped.
How many files can one submission contain?
Up to 5 files per submission, with a maximum of 5 MB per file. When a submission's uploads total 7 MB or less, they are also attached directly to the notification email; larger uploads stay available through signed links in the dashboard.
How do I set up a file upload form on my website?
Set the form method to POST, set enctype="multipart/form-data", point the action at https://splitforms.com/api/submit, and add a file input with a name such as resume or attachment. Then create an access key, connect Storage in the dashboard, and publish the form. No separate upload endpoint or client-side S3 signing flow is needed.
Does file upload work with React, Next.js, Vue, or fetch()?
Yes. Build a FormData object from your form ref or append the fields manually, append the access_key, and POST it to https://splitforms.com/api/submit. Do not set the Content-Type header yourself when sending FormData — the browser must add the multipart boundary.
Are uploaded files secure?
Yes. Files are stored privately, not in a public bucket, and are exposed through expiring signed download links (a 7-day window). SplitForms blocks executable and script-like extensions and sniffs the content type server-side. The accept attribute only filters the file picker; it is not a security boundary, so keep the server-side checks in place.
What file types can visitors upload?
Use the accept attribute to guide the picker, for example accept=".pdf,.docx,image/*". It is a convenience filter, not enforcement. SplitForms checks files server-side and rejects executable or script-like extensions regardless of what the form allows.
Where do uploaded files go after submission?
They appear with the submission in your SplitForms dashboard, with signed download links. Small uploads are also attached to the owner notification email, webhook payloads can include stored-file metadata, and the Google Drive integration can copy each uploaded file into a folder you own.
