About Compress PDF
Most of a PDF's size usually comes from photos and scans inside it. The compressor shrinks those pictures to a sensible sharpness, removes duplicate images and leftover data, and keeps text sharp and searchable. For forms that need a file under a limit — common for exam and government applications — use “Reach a size”.
Questions
Is it safe to compress a PDF 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.
How do I compress a PDF to 200 KB or 100 KB?
Choose “Reach a size”, pick 200 KB (or type any size) and press Compress. The tool tries stronger settings until the file fits.
Will the text get blurry?
No. Text and drawings stay sharp; only pictures inside the PDF are reduced.
Why didn't my PDF get much smaller?
PDFs made mostly of text are already small. If a file is mostly fonts and text, there is little left to remove.
Can I compress several PDFs at once?
Yes — add them all; you get one .zip with every compressed file.
Is it really free?
Yes — compressing is completely free, with no sign-up, no watermark and no daily limit.
Can I compress a PDF 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.
