FAQ
Is my file uploaded?
No. Compression runs in your browser and your file is never stored. The first time, your browser downloads the compression engine (about 1.3 MB).
Why did it barely shrink?
Files without photos or that are already compressed have little room to shrink. If the result would be larger, you get the original back.
Will text get blurry?
No. Text and vector shapes stay as they are; only photos are recompressed.
