Is text quality affected?

No. Only embedded images are recompressed; text and vector elements stay sharp and unchanged.

What's the difference between compression levels?

Light reduces image quality only slightly for a moderate size gain. Maximum reduces image resolution and quality more for a bigger size gain.

Is my file sent to a server?

No. Compression happens entirely in your browser: your PDF never leaves your device.

Why isn't my PDF smaller after compression?

If your file is mostly text or already well-compressed images, the possible reduction is naturally limited.

Merge, split, sign, and much more.

Your files never leave your device.
