Reduce PDF file sizes locally in your browser with no upload and clear quality controls.
No upload
Input
Reduce PDF file sizes locally in your browser. Text, vectors, and pages remain PDF content.
Your PDFs are processed only in this browser and are not uploaded.
Compressing creates a new PDF file. Existing digital signatures therefore remain not cryptographically valid.
Compression
Add at least one PDF file.
Image compression depends on the available qpdf WASM version. If unsupported, an error is shown.
Output
One new PDF is created per source. Multiple results are also provided as a ZIP file.
