Fill PDF Form

Upload a form and every fillable field (AcroForm) is listed automatically: text boxes, checkboxes, radio groups and dropdowns, each with its own input. Export keeps the form editable, or choose flatten to lock the content. Honest note: scanned documents that merely look like forms have no real fields and cannot be auto-filled — that case does not use your quota.

How it works (3 steps)

1

Upload the PDF form

Government applications, contracts and registration forms made with proper software carry real fields.

2

Fill in each field

All fields are listed by name — type, tick, or pick from dropdowns and radio groups.

3

Export and download

By default the form stays editable; choose flatten to lock the content so recipients cannot change it.

FAQ

Why does my PDF say "no form fields"?

Only PDFs built with embedded AcroForm fields can be auto-filled. A scan of a paper form, or a screenshot converted to PDF, only looks like a form — it has no real fields. We say so honestly and the run does not use your quota; the PDF editor tool can overlay text manually instead.

What does "flatten" mean?

Flattening bakes the filled values into regular page content: the fields disappear and recipients can no longer change them — ideal for final submissions. Without flattening the form stays editable for later updates.

Is my file uploaded to a server?

No. Field detection, filling, and export all run entirely in your browser.

Does a digital signature survive processing?

No. Any change to a signed PDF (merging, compressing, watermarking…) invalidates the existing digital signature — that is the tamper-proof design of PDF signatures, not a limit of this site. Process first, then sign.

Can I trust the processing engine?

Yes — and you can verify it: the tool runs on open-source in-browser engines (pdf-lib, pdf.js, Tesseract OCR…) on your own device. Open DevTools → Network while processing and you will see no file upload requests.
