Compress PDF Files Online — Free

Drop a PDF and get a smaller file back, ready for email or upload limits. The whole job runs in your browser — your document never leaves your device. No account, no upload, no waiting in a queue.

How much you can save depends on what's inside the file. Scanned PDFs and reports with photos compress 30–80% because we re-encode the embedded images at a lower resolution. PDFs that are mostly text barely shrink — there's nothing big to compress, and we'll tell you that on the next step instead of pretending we did real work.

You see the before-and-after size, a preview of the result, and decide whether to keep it. If a level you picked made things worse, we hand you back the original. Free for files up to 50 MB; Premium lifts the cap to 200 MB and unlocks Light and Maximum levels.

FAQ

Is it really free?

Yes. Files up to 50 MB at the Recommended level, no signup.

Are my files uploaded?

No. Everything runs in your browser — your PDF never leaves your device.

Why didn't my file shrink much?

Compression works mostly on embedded images. PDFs that are mostly text are already nearly as small as they can get.
