Why compress without uploading
Every upload to a compression site is a copy of your document on a server you do not control. Doing it in the browser avoids that copy entirely.
Aiming at an exact size?
Compression is really image compression, and most jobs are about hitting one specific number. We wrote up how to reach an exact size without wrecking the document, and why the work should happen on your device.
Frequently asked questions

No. Compression happens in your browser and the file never leaves your device.
Can I compress several files?+
Yes, you can compress files one after another; each is processed locally.

Yes, with no sign-up.
