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.
Frequently asked questions
Will 500 KB keep my scan readable?+
Usually yes. 500 KB is generous enough for most scanned documents to stay clear, unlike very tight caps like 100 KB.
Is my document uploaded?+
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.
Is it free?+
Yes, with no sign-up.
