Compress PDF
Reduce PDF size by recompressing images. Choose quality — all offline in your browser.
How it works
Drop a PDF, pick a preset (high/medium/low quality) and download the compressed file. We recompress embedded JPEGs; for scanned PDFs we rasterize pages to JPEG. Text-based PDFs may shrink little — that’s expected. Files over ~500 MB may fail (browser RAM). Before/after sizes are shown.
Privacy
Compression is local with pdf-lib + canvas. Nothing is uploaded.
