How to use it?
Provide the listed input and choose Compress. Review the result, then copy or download where available. Clear removes inputs and results.
Browser-local processing. No uploads, content logging, persistence or remote resource loading. Generated markup is inert text; files are treated as untrusted data.
Local native decoding/encoding; re-encoding removes metadata and flattens animation. PNG, JPEG and WebP bytes are verified. AVIF decoding depends on this browser; no AVIF encoding is exposed.
Actual output may be larger. JPEG uses an opaque white background. PNG optimization is not implemented; no fake PNG quality slider.
