Frequently asked questions
- What does flattening actually do?
- It paints each answer onto the page and then deletes the interactive field, so what was a typed-in value becomes part of the document itself. The text still selects, copies and prints exactly as before, but there is no longer a box to click into, so nobody can type over your answers or accidentally clear them. That is what an office means when it asks you not to send an editable form. Leave it switched off and the file stays a working form you can come back and change.
- Why does it say my PDF has no form fields?
- Because most documents that look like forms are flat: the boxes and lines are printed artwork, not real fields, and there is nothing in the file to fill. A PDF only has fields if whoever made it saved it as a fillable form. This tool fills the fields a form already has — it cannot add fields that were never there, so a scanned or printed-style form has to be filled by hand or obtained in its fillable version.
- Can it sign the PDF?
- No, and it deliberately does not pretend to. A digital signature is a cryptographic operation performed with a certificate that only you hold, so no in-browser tool can produce a valid one for you. Signature fields in your form are listed but left alone; if you flatten, the empty signature box is removed rather than replaced with something that merely looks like a signature.
- Why can't it draw the rupee sign or Hindi text?
- Field appearances are redrawn with a built-in Helvetica, which covers Latin, accents and most European symbols but not the rupee sign, Devanagari, CJK or emoji. When a value uses one of those, the answer is still written into the file and your PDF reader draws it with its own fonts — so it appears correctly in Acrobat and in most browsers — but that field cannot be flattened, because flattening bakes in the drawing and there would be nothing to bake.
- Will the rest of the document survive?
- Yes. The pages, text, images and page sizes are untouched — only the field values, and on flattening the field objects themselves, are changed. Links, bookmarks and comments come across unmoved, and the file's title, author and dates are left exactly as they were rather than being re-stamped.
- Is my PDF uploaded to a server?
- No. The form is read, filled and saved entirely inside your browser tab, so an application, claim or tax form — and everything you type into it — never leaves your device.
