How to fill a PDF form online
- Choose the PDF that has form fields you want to fill in.
- VitePDF finds every text box, checkbox, radio button, and dropdown, and shows how many it found.
- Click directly into each field on the page preview and fill it in, just like the PDF was designed for.
- Leave "Flatten after filling" checked to lock in your answers, then click Download filled PDF.
Why use VitePDF
- Fields are filled exactly where the form was designed for them — no guessing where to click or type.
- Flattening bakes your answers permanently into the page, so the result displays correctly and can't be altered further in any PDF viewer.
- Everything happens in your browser — your PDF is never uploaded anywhere.
Frequently asked questions
This PDF says it has no fillable fields — why?
Not every PDF that looks like a form actually has real AcroForm fields behind it — some are just an image or a fixed layout with no fields to click into. If VitePDF finds none, there's nothing built into the file for it to detect; try VitePDF's Sign a PDF tool to place text or a signature anywhere manually instead.
Should I flatten the form?
Usually yes — it's the safest option if you're sending the PDF to someone else, since your answers are baked in and can't accidentally be changed or blanked out afterward. Leave it unchecked only if you specifically want the recipient to still be able to edit the fields.
Is my file uploaded anywhere?
No — filling and flattening both happen entirely on your device using your browser's own processing power. Your PDF never leaves your computer.
Is there a file size limit?
Files up to 10 MB are free — Premium removes that limit entirely.
