Frequently Asked Questions
How much can I reduce an image?
As much as you need. For very small targets the tool also reduces the pixel dimensions so the file fits.
Will it work on PNG?
Yes. PNGs are re-encoded as JPEG, which compresses photographic images far more effectively.
Is it really free?
Completely free, with no limits, sign-up or watermark.
