Frequently Asked Questions
How much smaller will my PDF be?
Typical reduction is 30-70% depending on the content. Image-heavy PDFs see the biggest savings.
Will compression reduce the quality?
Text and vector graphics remain perfect. Images may be slightly optimized but remain visually crisp.
Is there a file size limit?
You can upload PDFs up to 250 MB. Most compressed outputs are well under email attachment limits.
Is this tool really free?
Yes, completely free with no hidden fees, no watermarks, and no sign-up required. You can convert as many files as you need.
Are my files private and secure?
