Compress PDF questions
Will every PDF become much smaller?
Not always. Results depend on how the original PDF was created. Files containing already-compressed images may show a smaller reduction.
Does compression change the page order?
No. The document keeps the same page order while the file is optimised.
Can I use this on a phone?
Yes. The interface is responsive and works on modern phones, tablets and desktop browsers.
Is my finished file saved automatically?
No. Nothing is saved to your profile automatically. If you are signed in, use Save to My Profile only when you want to keep a copy.
