Compress PDF
Reduce PDF file size in your browser by rebuilding pages as optimized images. Choose a quality level and download the smaller PDF.
This browser-based compressor rasterizes pages. Text remains readable but may no longer be selectable in the output.
Reduce PDF size without uploading it
Crucialio renders each page locally, recompresses it and rebuilds the document. This works especially well for scanned PDFs and image-heavy files.
What to expect
Maximum compression is best for screen viewing. Higher quality keeps more detail for printing. PDFs that are already highly optimized may not become smaller.
