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)
Upload the PDF form
Government applications, contracts and registration forms made with proper software carry real fields.
Fill in each field
All fields are listed by name — type, tick, or pick from dropdowns and radio groups.
Export and download
By default the form stays editable; choose flatten to lock the content so recipients cannot change it.

FAQ
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.
Try it ↑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.
Try it ↑No. Field detection, filling, and export all run entirely in your browser.
Try it ↑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.
Try it ↑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.
