Compress PDF Online — Reduce PDF File Size
Shrink PDF file size in your browser with three quality presets and an instant before/after size preview.

Email attachment too big? Upload portal rejecting your file? PDF Suite Pro’s PDF compressor reduces file size dramatically — often by 50–90% — with three quality presets so you choose the balance between size and sharpness.
Compression happens entirely in your browser: your PDF is never uploaded, there’s no queue, and you see the new file size before you download. Perfect for compressing scans, reports and presentations with lots of images.

Frequently asked questions
How much smaller will my PDF get?
It depends on the content — image-heavy scans often shrink 70–90%, while already-optimized text documents shrink less. The tool shows you the exact result before you download.
Does compressing a PDF reduce quality?
Compression re-renders pages at a chosen image quality. The “high” preset is visually near-identical for most documents; “smallest” trades some sharpness for maximum size reduction. Note that text becomes part of the page image, so pick “high” if you need to keep it crisp.
Is it safe to compress confidential PDFs?
Yes — the file is compressed locally in your browser and never uploaded to any server.
