In short Fill PDF forms is a free web tool that fills text, checkbox and choice fields in a fillable PDF, shows the actual result before saving, and keeps the fields editable. It runs in your browser with no install or sign-up, and your files are processed in this device’s browser — never uploaded to a server. One fillable PDF up to 20MB, 100 pages and 100 fields. PDFs without fields, and password-protected, signed, calculated or XFA forms aren’t supported.
BEFORE → AFTER
A blank leave request, 7 fields filled
We added a fillable leave request form (12,572 bytes) and filled in Name, Department, Leave type (a dropdown), Dates, Reason, Emergency contact and the handover checkbox. Result: “1 pages retained · 7 of 7 fields changed,” 22,553 bytes — larger because the font is embedded. Reopening the saved PDF, all 7 fields held exactly what we typed.
Actual result of filling a leave request for a fictional employee, “John Smith” (company and name are examples), with Fill PDF forms v0.1.8, then reopening the saved PDF to check the field values.
HOW TO
Three steps and done
Add the PDF form
Pick a PDF that has fields, and the field list appears next to the original form. Click a field to see the page it is on.
Fill the fields
Type in text fields, choose from dropdowns and click checkboxes. If you change something by mistake, press “Restore original values.” Text size can be 10, 12 or 14.
“Preview filled PDF,” then save
The first time, about 23MB of font data is prepared before the result is drawn. Check every page in the preview and press “Save.” You can carry on with “Rename files.”

GOOD TO KNOW
Good to know
- One fillable PDF · 20MB · up to 100 pages and 100 fields.
- It does not create new fields on flat PDFs. Encrypted or already signed PDFs and forms with calculations, scripts or XFA are not supported. Empty signature fields are kept.
- Text shrinks to fit a field, down to size 8; if it still overflows, saving stops and tells you. Break long multi-line text into lines yourself.
- Fields stay editable in the saved PDF. Other PDF editors may use a different font for newly typed characters.
- The PDF engine is downloaded once, about 4MB, the first time. It's fetched only after you pick a file, and other PDF tools reuse it.
