Frequently asked questions
Will compression ruin my photo?
At 75% most photos look identical on screen. For text-heavy graphics, stay at 85% or higher so edges stay sharp.
Is my image uploaded to a server?
No. Compression happens with canvas in your browser — the original never leaves your device.
What formats can I compress?
JPG, PNG and WebP inputs are accepted. The output is always JPG, which is smallest for photos.
How much can I save?
Typical phone photos shrink by 50–80% at 75% quality with no visible difference on a blog page.
