MegaPDF: Fill & Sign PDFs

Open. Fix. Save. Done. MegaPDF does the one job most people actually have with a PDF: someone sent you a form, and you need to send it back filled in, checked off, and signed. No account. No subscription. No cloud. Everything happens on your device. Check any box Tap a checkbox and it's checked — real interactive form fields and plain printed squares alike. MegaPDF recognizes drawn checkboxes that other apps treat as decoration. Type on any line Tap where the answer goes and type it. Choose the size and the face — sans, serif or monospace — so what you add matches the form you are filling in. Drag it into place, or tap it again to fix a typo. Everything you add is real, searchable text, not a sticker on top of the page. Fix the document's own text Wrong date? Misspelled name? Tap the line and retype it. MegaPDF keeps the document's own font where it can and tells you when it had to use a similar one. If a change would disturb the rest of the page, it says so instead of quietly moving things. Undo puts the original back exactly. Redact, and it really is gone Mark what has to come out — a name, an address, a picture — and MegaPDF takes it out of the file rather than covering it over. What was underneath is gone: no other app can copy it or search for it. Sign like you mean it Draw your signature with a finger, type your name, or use a photo of the one on paper — the white background disappears automatically. Your signatures stay in a private library on your device; drop one on a document and move and resize it until it sits right on the line. Save without fear Save writes back to the original file — safely. MegaPDF checks every save first, so a failed one can never corrupt the file someone sent you. Or keep the original and save a copy. Export as Markdown writes the document's text — headings, lists, the values you filled in — as a Markdown file, and leaves the PDF as it was. You can also put a password on a document, or take one off. Find any word Search the whole document as you type: every match lights up and the counter says how many, so the one clause you need in a forty-page lease is a few taps away. Read it, not the app Reading mode takes the toolbars off the screen and leaves the page. Page colours come with it: Sepia for a long read, Night for a dark room — and Night inverts pictures too, deliberately. MegaPDF can open every document that way. Put the pages in order Rotate a page that came in sideways, delete one, drag pages into the right order, insert a blank page, add the pages of another PDF, or save a few pages out as their own file. Each is a single step, and one Undo puts it back. Private by design MegaPDF asks you for no permissions and makes no network connections. Your documents and your signature never leave your device — there is no server for them to go to. The app is open source, so anyone can verify that. Works with everything Open a PDF from Files, Google Drive, Gmail or any app that hands one over — MegaPDF is in their Open with list — and send it back with Share. Documents you fill and sign here open perfectly in Adobe Acrobat and in any desktop PDF app. MegaPDF is deliberately simple: it doesn't bury you in toolbars. It opens, it fixes, it saves. Done.
