Image Compress: Web Worker + Format Convert

Typical scenarios: ① compress images in bulk before uploading; ② slim down images for a website; ③ output different formats per scenario, or convert phone photos to a common format.

How to use: upload images, pick the target format and quality (0–100), and click Compress. Compression runs in the background without interrupting other tasks — preview and download when it's done.

Notes: ① quality around 80 is usually indistinguishable to the eye — too low distorts, too high bloats the size; ② photos suit JPG/WebP, while transparent icons and line art suit PNG; ③ compression is lossy and repeated compression accumulates loss — keep your originals.
