Questions
Is it really free?
Yes. Compressing to any size is free and unlimited. No account, no watermark.
Do you upload my documents?
No. The compression engine runs inside your browser. Turn off Wi-Fi and it still works.
What if it cannot reach 300 KB?
Very long scans may not fit. We show the smallest size we reached and suggest removing pages or using grayscale.
Will my text still be readable?
Yes. We try a lossless optimisation first. If that is not enough, pages are saved as optimized images at the highest quality that fits.
Does it work on my phone?
Yes, on Android and iPhone browsers. You can also install it like an app.
