Image Compress

Batch compress to WebP/JPG with max dimension and quality controls.

Image compression runs locally in your browser; nothing is uploaded. Dimensions match the source: PNG lossless repack via Oxipng (WASM) when unchanged size/no scaling—often smaller than re-encoding on canvas; JPG/WebP still re-encoded by quality. If output is not smaller for the same format, the original is kept. Default follows each source format, or pick a unified format below.
