Why use this PDF compressor?

Compress in seconds

Your PDFs are compressed directly in your browser — no waiting for uploads to a server. Most files are done in under five seconds.

Three compression levels

Choose between Screen, Recommended, or Print quality. Whether you need the smallest possible file or near-original sharpness, there's a setting for it.

Batch compress PDFs

Drop in multiple PDFs at once and compress them all in one go. Download individual files or grab everything as a single ZIP.

See exactly how much you saved

After compression, each file shows its original size, new size, and percentage reduction — so you know exactly what you're downloading.

Stays on your device

Your PDF never leaves your browser. Processing happens locally, so sensitive documents stay private — no uploads, no cloud storage.

Works on any device

Compress PDFs on your phone, tablet, or computer — no app to install. Works in any modern browser on iOS, Android, Windows, or Mac.

Sometimes you just need a smaller PDF

The email that kept bouncing

You've spent the better part of an afternoon putting together a proposal. It's thorough — charts, screenshots, a few scanned signatures — and by the time you've exported it, the PDF clocks in at 18 MB. Your client's email server has a 10 MB attachment limit, and it keeps bouncing back.

You don't want to remove anything. The charts matter. The scanned pages are necessary. You just need it to be smaller.

You drop the file into the PDF compressor, pick "Recommended," and click compress. Twelve seconds later, the same document is 4.1 MB. You check it — everything still looks sharp on screen, the text is clear, the charts are readable.

You send it. It goes through first try. The client replies within the hour.

A year of invoices, finally under control

You're freelance, and at tax time you realise you've been emailing your accountant one PDF invoice at a time — each one a 3–5 MB scan from your phone's document scanner. You've sent over sixty of them. Your accountant asks if you can resend them in a smaller format so they fit in a shared folder with the rest of the year's documents.

You drag all 60 PDFs into the tool at once. You pick "Screen" — these are just invoices, readability is all that matters — and hit compress. The tool churns through them one by one, and within a minute you have a ZIP file ready to download. The whole archive has gone from 240 MB to just over 30 MB.

You send the ZIP. Your accountant replies with a simple "Perfect, thanks." You make a note to compress as you go next year.
