    Password and info

    Protected with AES-256. Opened a protected PDF? It's saved without its old password unless you set one here.

    Scanned pages (OCR)

    Reads the text in scanned pages so you can search, copy and edit it. It runs on your device; the first run downloads the reader (about 7 MB).

    Sign in to download

    Downloading needs a free FitMyKB account. Your edits stay right here while you sign in, in a new tab.

    We never store your PDF. It's edited on your device and never uploaded. Your account only holds your name and email.

    Find and replace

    Replaces the PDF's own text, keeping its font where every letter exists in it.

    What you need

    Just the PDF on your phone (in Downloads, Files, WhatsApp or Gmail) and a browser: Chrome on Android, Safari on iPhone. Nothing to install, no account to edit. The PDF opens in the page below and stays on your phone; it isn't uploaded anywhere.

    1. Open the PDF

    Tap Open a PDF to edit and choose the file. From WhatsApp or Gmail, save the PDF first (tap it, then the download or share button, then Save to Files). Pinch to zoom, and use the page buttons to rotate or delete pages.

    2. Change words that are already in the PDF

    Tap Edit text, then tap the line you want to change: a name, date, amount or spelling. Type the new text and tap Enter. The old words are removed and the new ones use the same font whenever the PDF contains every letter; otherwise a matching font is used, and the editor tells you.

    3. Add text, a tick or a date

    Tap Add text and tap where it should go, for example on a form line. Tick and Cross mark boxes, and Date adds today's date. Drag anything to move it; pull the round corner handle to resize it.

    4. Sign it

    Tap Sign and draw your signature with your finger, or choose From a photo and pick a photo of your signature on white paper: the paper is removed and only the ink stays. Place it on the line and resize it.

    5. Download, small enough to upload

    Portals often limit PDFs to 200 KB or 1 MB. Type the limit next to Save under, then tap Download. The first time, sign in with a free account. The PDF is saved to your Downloads (Android) or Files (iPhone), ready to attach or upload.

    Common problems

    If you can't tap the text of a scanned PDF, it's a photo of text: open Document, then Scanned pages (OCR), to read it first. Protected PDFs ask for their password. If a PDF is very large, close other apps; a few hundred pages work on most phones.

    Use cases

    No laptop nearby

    Fix a detail in a PDF, sign it and send it from your phone in a few minutes.

    Avoiding app installs

    Edit in the browser instead of installing PDF apps that ask for subscriptions or permissions.

    Documents from WhatsApp

    Open a PDF someone sent on WhatsApp, fill it in, and send it back.

    How it works

    1. Open the PDF from your phone.

    2. Tap Edit text, Add text or Sign and make your changes.

    3. Set a size limit if needed and tap Download.
