Two honest ways to shrink a PDF
Keep text finds the photos and scans embedded in your PDF and recompresses them at a smarter quality โ the text layer, links and vector graphics stay untouched and selectable. This is the right mode for reports, scans and presentations, and it routinely cuts 50โ80% off image-heavy files.
Maximum redraws every page as a compressed image. It produces the smallest possible file โ but text stops being selectable, exactly like a scan. Use it when the size limit matters more than anything else.
Both modes run entirely in your browser. A contract, a medical report, a bank statement โ the documents people compress are precisely the documents that should never visit a stranger's server. Here they physically cannot.
Frequently asked questions
Why did my PDF barely shrink?
It was probably mostly text and vector graphics, which are already tiny. Compression wins come from photos and scans inside โ if there are none, try the Maximum mode, or accept that the file is already efficient.
Will the text stay selectable?
In "Keep text" mode โ yes, completely: only the embedded images are touched. In "Maximum" mode pages become pictures, so text is no longer selectable or searchable.
Is there a file size limit?
No hard limit. Very large files are bounded only by your device's memory, since everything runs locally.
