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% privado — los archivos se convierten en tu navegador y nunca se suben.
Drop a PDF — it loads locally, with no upload.

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.
