Real size reduction
We garbage-collect unused objects, deflate the content streams and fonts, and recompress images — often a big drop in size.
Lossless where it counts
Text and vector graphics stay pixel-perfect; only redundant data is squeezed out.

Common questions
Is this a Pro tool?
Yes — the PDF tools are part of the Pro tool set (Pro, Business and Enterprise). The everyday format converters stay free.
Will it reduce quality?
Text and vector content are kept lossless. Images are re-deflated rather than re-sampled, so visible quality is preserved while redundant data is removed.
Why didn't my PDF get much smaller?
Some PDFs are already optimised, or are mostly high-resolution photos. Those compress less. A scanned, image-heavy PDF usually shrinks the most.
Is there a file size limit?
Pro raises the limit to 500 MB per file with 3,000 credits a month; larger plans go higher.
