How it works
- Add the PDF.
- Choose a mode. 'Keep text' is safe and often saves little. 'Rasterise' is much smaller and turns the text into a picture.
- Check the before and after sizes, then download.
When the browser is not enough
Scanly for Android
Live edge detection through the camera, text recognition that makes the PDF searchable, a signature you can place, and batch capture. All of it on the phone.
In closed testing. There is no public Play link yet, so there is no button here yet.
Scanly Pro
Pro is the paid tier in the Android app. It cannot be bought on the web yet — checkout is not connected, and we would rather say that than show you a price you cannot pay.
Questions
Do my files get uploaded?
No. The rewrite happens in your browser.
Which mode should I pick?
'Keep text' first — if it gets you under your limit, take it, because the text stays selectable and searchable. Only rasterise if you need the file much smaller and you can live without selectable text.
Why did 'Keep text' barely change anything?
Because that mode only rewrites the file's structure — it drops unused objects and repacks streams. If your PDF is big because of photographs, there is nothing there to win, and the page will say so rather than pretend.
What exactly does 'Rasterise' destroy?
Selectable text, copy and paste, text search, links, form fields and any accessibility structure. Every page becomes a photograph of itself. It is the right choice for a scan and the wrong one for a contract.
Is a compressed scan still readable?
Usually yes at the default quality. The preview shows a 100% crop of the busiest page before you download, so you can judge it rather than trust it.
