Frequently asked questions
Which method should I use?
Use "Optimize structure" for normal documents - it keeps text sharp and selectable. Use "Strong compression" for scans and photo-heavy PDFs where the biggest reduction matters; text will no longer be selectable.
What if the file does not get smaller?
Kitly keeps your original when it cannot make the file smaller, so you never end up with a worse file.
Are my files uploaded to a server?
No. Kitly runs entirely in your browser. Your files are opened and processed on your own device and are never sent to us or anyone else. You can even turn off your internet connection after the page has loaded and the tool will keep working.
Is it free? Do I need an account?
Kitly web tools are free to use with no sign-up, no watermark and no daily limit. For heavy daily use, the Kitly Android app brings the same tools to your phone.
