Frequently asked questions
How much smaller will my PDF get?
Scanned and image-heavy PDFs usually shrink the most. Text-only files are already compact, so the saving is smaller.
Does compressing lower the quality?
Fast mode reduces image detail the most. Balanced keeps documents readable, and Quality is closest to the original.
Is Compress PDF free to use?
Yes. There is no account, no daily limit and no watermark. Files can be up to 200 MB each.
What happens to my files?
Uploads and results are stored only while the job runs and are deleted automatically about 15 minutes later.
