For upload portals with a size limit. Tries lossless first, so text stays selectable whenever that is enough.
What this does
With a target size, the file is first repacked losslessly; if that lands under the limit, text stays selectable. Otherwise each page is re-encoded as an image at the highest quality and resolution that still fits. Without a target, Lossless mode repacks the file structure (a small saving) and Strong mode rasterises every page (a large one).
Limits
- Reaching a small target usually means rasterising pages, so text stops being selectable and searchable.
- Pages are never rendered below about 45 dpi. If a document cannot fit and stay readable, the tool says so instead of handing back an unreadable file. Splitting it first usually helps.
- Lossless mode often saves only a few percent. That is the honest ceiling for structural compression.
Is this private?
Yes, and you can check rather than take our word for it. Open your browser's network tab and run the tool: your file never appears in it, because there is no server to send it to. The whole site is static files.
