PDF Editor & Scanner - Free

About this app

Edit PDFs, scan documents, redact confidential text and sign — all on your phone. Your documents are never uploaded: every edit, scan and OCR pass runs on-device. Free to use, with an optional Pro upgrade and a few unobtrusive ads to support the free tier.

EDIT TEXT IN ANY PDF
Change text directly in a normal PDF, and — unusually — in a scanned one too. WhatsClaw finds the words in a photographed page and replaces them, matching the original size and weight. Most editors cannot touch a scan at all.

DOCUMENT SCANNER
Point the camera at a page. The edges are found for you, the perspective is flattened, and uneven lighting is removed so the paper comes back white — even under a warm bulb, and even on a page half in shadow. Choose Auto for white paper, Colourful for brochures and coloured forms, Grey, or B&W for the sharpest text and the smallest file. Export at full sensor resolution, or lossless when nothing may be thrown away.

REAL REDACTION
Redacted text is removed from the file, not covered with a black box. Try selecting it afterwards — there is nothing there. Sweep a whole document for ID numbers, emails or phone numbers in one pass. Most apps that say "redact" simply draw a rectangle, and the words underneath can still be copied out.

SIGN AND FILL
Draw or import a signature. Sign with a real digital certificate (PKCS#12) with an RFC 3161 trusted timestamp, so the signature outlives the certificate. Fill and flatten form fields. Add signature fields for someone else to sign.

CONVERT
Word, Excel and PowerPoint to PDF, laid out properly — real tables with borders, images, alignment, spreadsheet colours, page numbers. PDF back to Word or Excel. Images to PDF. Merge, split and extract pages.

ORGANISE PAGES
Reorder, rotate, delete, duplicate, insert, crop. Thumbnails, bookmarks, outline, full-text search, night mode.

MAKE SCANS SEARCHABLE
Built-in OCR adds an invisible, searchable text layer in Latin, Devanagari, Chinese, Japanese or Korean scripts — running on your device, not on a server.

PROTECT
Set or remove a password with permissions. Strip metadata and embedded attachments before sharing. Compress to shrink a file for email.

WHY ON-DEVICE MATTERS
Every editing, scanning and OCR feature above runs on your phone. Your contracts, medical records, ID documents and statements are never uploaded — the documents themselves never leave your device. There's no account to create; sign-in is anonymous and automatic. A few small pieces of app data do leave the device: anonymised usage analytics, ad requests (WhatsClaw shows ads and offers an optional ad-free Pro subscription), and — only if you sign with a digital certificate and tick the box — a one-way hash of the signature for a trusted timestamp, never the document itself.

FREE PDF EDITOR FOR ANDROID
Looking for a free PDF editor for Android that doesn't box you in? Text editing, annotation, redaction and page tools all work without a subscription — no trial period, no feature ceiling.

PDF SCANNER AND IMAGE TO PDF CONVERTER
Turn a photo into a clean, searchable PDF in seconds. Scan receipts, notes, ID cards or whole notebooks, or convert existing images straight to PDF — scanning stays free for everyone, always.

SIGN PDF DOCUMENTS AND FILL FORMS
Fill in any PDF form and add a signature — a quick drawn signature for everyday paperwork, or a real digital certificate with a trusted timestamp for documents that need to hold up.

Open source licences for every library used are listed in Settings.
