Shrink a PDF's file size right in your browser. Nothing is uploaded — the PDF is optimized on your device, and you only get the smaller file (never a bigger one).
100 % privat — Dateien werden in Ihrem Browser umgewandelt und niemals hochgeladen.
Drop a PDF — it loads locally, with no upload.
The file is optimized in your browser; scanned and image-heavy PDFs shrink the most.
Save the smaller PDF — the original is never modified.
Scanned documents and image-heavy PDFs shrink the most, because their images are re-encoded at a smaller size. Text-only PDFs are already compact, so they're optimized losslessly and may only shrink a little.

No. The conversion runs entirely in your browser using JavaScript — your file never leaves your device, so it's safe even for sensitive documents.
Yes — completely free, no signup, no watermark, and no daily limits.
