What this tool does
PDF compression is a trade-off, not a magic button. This tool re-encodes each page as an image at the quality you choose, which can shrink scanned documents dramatically but can also soften text and remove selectable text.
A smaller file without an upload. Everything runs in your browser; your file is not uploaded.
Scanned packets, image-heavy decks, and upload forms with a strict file-size limit.
Contracts, invoices, or accessibility-sensitive documents where text must remain searchable and selectable.
Honest about the trade-off
The output is image-based. Keep the original when selectable text, links, or sharp line art matters.
Quality control
Pick a high, balanced, or small setting and compare the result before replacing the original.
Browser-first
Everything runs in your browser; your file is not uploaded.
No install, no lock-in
Open the page, finish the job, and copy the result. No desktop software.
