Compression re-renders pages as images, so text won’t be selectable afterward — ideal for scans, less so for PDFs you still need to copy text from.

FAQ
Compression questions
It depends on what’s inside. Scanned documents and photo-heavy PDFs routinely shrink 60–90%. PDFs that are mostly text are often already efficient — and if compressing yours would not help, the tool says so instead of handing you a bigger file.
This compressor works by re-rendering each page as an optimized image, which is what makes scans shrink so dramatically. The trade-off is that text becomes part of the image. If you need selectable text and a smaller file, try the Light level first.
No — the rendering and rebuilding all happen in your browser’s memory. This is unusual: most compression sites process your file on their servers. Yours stays on your machine start to finish.
Most email services cap attachments around 20–25 MB. Court e-filing portals commonly cap at 10 MB or even 5 MB. Government application forms vary widely. Strong mode targets these limits.
