A browser-based image compressor for PNG, JPEG, WebP, and AVIF, with a parallel HTTP API for developers.

Landing page captured for the 2026-09-20 issue.

For: People compressing images or integrating image conversion into software
Worth noticing: The browser accepts up to 20 files, while API results reportedly expire after one hour.

Field notes

The page separates a no-upload browser workflow from a server-based API. The browser tool accepts pasted screenshots and batches of up to 20 files, while the API exposes a keep-or-convert parameter for PNG, JPEG, WebP, and AVIF and returns size metadata alongside a download URL. The site attributes its processing to WebAssembly, libimagequant, and mozjpeg, and says API output is removed after one hour.
