Fill PDF Forms
Type into the fields of a fillable PDF, tick its boxes and pick its options, then download the filled form — privately in your browser. Nothing is uploaded.
How to fill in a PDF form
- Add the PDF form. Its first page appears with every field ready to type into; use Previous, Next or the page number to move through it.
- Click a field and type, tick the boxes and pick options from the lists. Tab moves to the next field, and Next empty field finds the ones you have not answered yet.
- Click Save filled PDF, check the preview, then download it. Switch on Lock answers first if nobody should change them, or send the result to Sign PDF to add your signature.
Which forms work, and what changes in the file
Any PDF made with fillable fields — text boxes, check boxes, radio buttons, drop-down lists and list boxes — the kind Adobe Acrobat, Word's "Export as PDF form", LibreOffice and most government and school sites produce. A PDF that only looks like a form (a scanned sheet, or lines printed on the page) has no fields; for those, Sign PDF places text and dates anywhere on the page.
What changes in the file
Only the fields you change are rewritten, in place: pages, other fields, links, bookmarks and document information stay as they are. Each changed field gets a new appearance so every PDF reader shows the answer the same way; check boxes and radio buttons keep the form's own tick style. With Lock answers on, every field is drawn into its page and removed, so the answers can no longer be edited.
Refused and special forms
Encrypted forms are refused (remove the password with Unlock PDF first), and so are forms that already carry a digital signature, because saving a filled copy would invalidate it. XFA-only forms — "Please wait…" forms that open only in Adobe Reader — cannot be filled outside Adobe's software. Some forms carry both an XFA version and a standard one; the standard one is filled and the XFA part removed so that every reader shows your answers.
Frequently asked questionsUseful details
8 answers +
Is my form uploaded?
No. Opening, rendering and filling happen in your browser. The PDF and every answer you type stay on your device and are not written to storage either — they live in this tab until you reload or close it. Website hosting and performance measurement are described in our Privacy notice.
Will the filled form still be editable?
Yes, by default. Your answers go into the form's own fields, so you or the recipient can open the file in any PDF reader and change them. Switch on Lock answers before saving to draw the answers into the pages instead; then they can no longer be edited.
My PDF has no fields to fill. What now?
Then it is a flat form: a scan, or lines printed on the page, with nothing to type into. Open it in Sign PDF, which places text, dates and your signature anywhere on the page. The tool offers that button when it finds no fields.
Can I type in Turkish, Polish, Greek or Russian?
Yes. Answers the standard PDF font cannot spell are drawn with Liberation Sans, an open-licensed font embedded in the file, so letters such as ş, ğ, İ, ł, ř, Greek and Cyrillic appear exactly as typed. Chinese, Japanese, Korean and Arabic are not supported yet; the tool names the field instead of saving boxes.
Why didn't the total calculate itself?
Some forms contain small programs that add up totals, reformat dates or check what you typed. Those scripts are not run here, so type the final values yourself. The saved file still contains the scripts, and a reader such as Adobe Acrobat may run them when the recipient opens it.
Can I sign the form too?
Yes. Fill it here, save, then use Send to → Sign PDF to draw, type or upload your signature and place it on the signature line. Empty signature boxes in the form are shown here as a reminder.
Can I fill it on my phone?
Yes. Tap a field to type; the page fills the width of the screen and the page number field jumps to any page. Small check boxes are easier to hit with the page zoomed in your browser.
Which forms are refused?
Password-protected or restricted forms (remove the password with Unlock PDF first), forms that already carry a digital signature — filling them would invalidate it — and XFA-only forms that open only in Adobe software. This is not a redaction or metadata-removal tool.
