Washi
Edit, fill, sign, and read scanned Persian, Arabic and Hebrew
A PDF editor that changes the words on the page, fills in any form, signs with real cryptography, and reads scanned Persian, Arabic and Hebrew that Acrobat has no OCR for — entirely on your own device.
One purchase covers your Mac, iPad and iPhone. No subscription, no in-app purchases, no account.
Nothing leaves the device
Your documents stay yours.
Most PDF tools ask you to upload the document to a server you have never heard of, in a country you did not choose, to do work your own computer is perfectly capable of.
Washi does all of it on the device in your hands: editing, form filling, signing, and reading scanned pages. It makes no network connections at all — not for features, not for licensing, not for analytics.
There is no account, no subscription and no trial that expires while you are mid-sentence.
Edit text in place
Change the words, not a box on top of them.
Click a paragraph and type. Washi removes the original text from the page and sets yours in the closest match to the document's own font, size, colour and line spacing.
Longer sentences wrap within the same column. Nothing shifts, and there is no white rectangle pasted over the old words for everyone to see.
The paperwork you actually get sent
Four kinds of document, one app.
Forms with fields
Type into real form fields, tick boxes, choose from lists. Tab through them the way the form's author intended.
Forms that are only lines
Plenty of forms are just printed rules on a page. Add Text puts your answer on the line, sized and aligned as if it had been typed there.
Signatures
Draw, type or photograph your signature once. Place it with a tap and it settles onto the signature line at the right size.
Scans
Text recognition writes what it reads over the page invisibly, so a photograph of a contract becomes something you can search, select and copy.
Document unchanged since signing
Signatures that hold up
A signature anyone can verify.
A picture of your name is fine for a delivery slip. For anything that matters, Washi signs the document itself: a standards-based digital signature that Adobe Acrobat, Preview and every other serious PDF reader can check.
The private key is created inside your device's Secure Enclave, where it cannot be copied, and every signature asks for Face ID, Touch ID or your password. Change one character afterwards and the signature shows as broken — which is the entire point.

Paper to PDF
The camera you already carry is the scanner.
Point your iPad or iPhone at a page. Washi finds the edges, straightens the perspective and cleans it up. On the Mac, the same camera works through Continuity Camera without getting up.
Then Recognize Text reads the page — about thirty languages through Apple's own engine, plus Persian through a second one built into the app. Both run on the device.
Getting the words out
A Persian book that opens the right way round in Word.
Export to plain text or to Word. Right-to-left paragraphs are marked as such in the file itself, which is what Word reads — so they open against the right margin, with the punctuation and the numbers where they belong.
And when a document has been through another converter already, its text is often in fragments: a word per object, in no order. Washi looks before it writes, says what the layer is worth, and offers to read the pages again with its own recognition instead. Sixteen fragments of thirty-three words became two paragraphs of twenty-nine, in reading order. No other PDF app offers to do that for you.
On the Mac
A real Mac app, with the shortcuts in your fingers.
Thumbnails down the side, tools across the top, and the keys where anyone who has used a PDF for a living expects them: ⌘= and ⌘− to zoom, ⌘0 to fit the page, Space to drag it, single keys for the tools.
Merge, split, extract and rotate pages. Print. Universal for Apple silicon and Intel.
Added for 1.0
The jobs a PDF actually arrives with.
Each of these was built because a document turned up that needed it, and each is checked by something that is not us — the file is handed to other software and asked what it can read back out.
Smaller, with the words kept
Every single-purpose app that shrinks a PDF turns the pages into pictures and throws the text layer away without telling you. Washi carries it across. And when a document would not meaningfully shrink, it says so and writes nothing rather than ruining it for no gain.
Redaction that removes
The words are deleted from the file, not hidden under a black box anyone can select underneath. You are shown what will go before it goes.
A word across every page
CONFIDENTIAL, DRAFT, محرمانه — drawn into each page's own content, so it is not a note anyone can delete and not text anyone can select. Your document's own words are left exactly as they were.
An archival copy
PDF/A-2b, the form libraries, registries and government offices ask for. Not a label: the output is checked against veraPDF, the reference validator, and passes all 144 of its rules.
Pictures, both directions
Photographs into a PDF the right way up — a phone stores a photo sideways with a tag saying how far to turn it, and ignoring that tag is why so many of these documents arrive on their side. And pages out as PNG or JPEG, with the resolution written in so Word and Pages place them at their proper size.
Text and Markdown in
A .txt or .md file becomes a PDF with headings, lists and bold — and Persian, Arabic and Hebrew paragraphs starting at the right margin, with the letters joined as letters rather than as the shapes they are drawn with.
The rest of it
Everything else you open a PDF editor for.
Markup
Highlight, underline, strike through, sticky notes, shapes and freehand drawing — with Apple Pencil on iPad.
Pages
Merge several PDFs, split one into parts, extract a range, rotate what came in sideways.
Persian, Arabic and Hebrew
Read, edited, searched and stamped in the right direction, because the document decides and not your device's language. Searching folds the differences people actually type: the Arabic ي and ك for the Persian ی and ک, a space where the keyboard has no half-space key, Hebrew without its points.
Forms Acrobat locks up
Adobe XFA forms only open in Adobe's own apps. Washi recognises them and tells you plainly, instead of showing you a blank page that says Please wait.
