Questions
How do I reduce PDF size in KB?
Choose “Reach a size”, pick or type the KB, and press Compress.
Is it safe to reduce a PDF's size here?
Yes. The work happens inside your own browser, so the file is never uploaded to a server — not ours, not anyone's. That makes it safe for contracts, bank statements, ID cards and other private documents.
Is it really free?
Yes — size reduction is completely free, with no sign-up, no watermark and no daily limit.
Can I reduce PDF size on my phone?
Yes. It works in the browser on Android phones, iPhones, tablets and computers. Nothing to install. It works best in Google Chrome.
