Frequently asked questions
How much smaller will my PDF get?
It depends on the content. Image-heavy PDFs often shrink 50–90%; text-only PDFs less. If we can't make it smaller, you get the original back with a note.
Is my PDF uploaded to a server?
No. Compression runs entirely in your browser, so your document stays private.
Why did my compressed PDF come back unchanged?
Some PDFs are already well optimized. If re-encoding can't reduce the size meaningfully, we return the original rather than a larger file.
