Can compressed output become larger?

Yes. Tiny or already optimized images can grow after re-encoding.

Does the quality slider affect PNG?

This tool targets JPEG and WebP because canvas PNG encoding does not expose a comparable quality control.

About the Image Compressor

The Image Compressor combines lossy canvas encoding with an optional maximum width. It reports source and output byte sizes so quality can be balanced against measurable savings.

How to use the Image Compressor

Choose a JPEG, PNG or WebP image.
Set quality, output format and optional maximum width.
Compress, compare the preview and download only when the tradeoff looks good.

Practical tips

WebP often gives useful photographic savings at quality around 0.75-0.85.
Repeatedly recompressing the same lossy file compounds artifacts.
