Compress PDF without wrecking quality

Compression is always a trade-off, so this tool aims for the sweet spot: meaningfully smaller, still perfectly legible. It works best on scanned or image-heavy PDFs, and if it can't beat the original size, it simply returns your original.

Frequently asked questions

How much smaller will it be?+

It depends on the content; scanned and photo-heavy PDFs shrink the most. If we can't beat the original, you get the original back.

Will the text stay selectable?+

Compression re-encodes pages as images, so text becomes part of the image. Use it when small size matters most.
