Questions
How much smaller will my PNG get?
Screenshots and graphics with lots of color often drop 50–70%. Already-optimized files change less — and we never return a file larger than the original.
Will it stay a PNG with transparency?
Yes. Output is a PNG and any transparency in the source is kept.
Is there a file limit?
No account and no arbitrary cap. Everything runs locally, so the only limit is your device's memory.
