FAQ
How does it hit the target size?
It lowers quality first, then resolution, repeating until the result fits.
Is the EXIF removed?
Yes — re-encoding through a canvas drops metadata as a side effect.
Can I batch compress?
This page handles one image; the batch tools cover watermarking and metadata.
