Frequently asked questions
Will compressing reduce the quality?
It can, depending on the level you choose. Lighter levels keep more quality; stronger levels make the smallest file.
Are my files uploaded anywhere?
No. Compression happens entirely in your browser, so your PDF never leaves your device.
Why is my PDF so large?
Usually because it contains scanned pages or high-resolution images. These compress the most.
