Common questions

Will compression reduce quality?

Low and Medium are lossless cleanups. High also downsamples eligible scan and photo images, capping them at 1,600 pixels. Text, vectors, links and forms stay as PDF objects.

What if my PDF does not get smaller?

An already optimized PDF may not shrink much. Results depend on what is inside the file.

How much can I compress at once?

Up to 20 files, 250 MB in total, 500 pages per file and 2,000 pages in a batch.
