In their own words
MumenLabs Image Compressor
MumenLabs Image Compressor is a browser tool for compressing, resizing, and converting images locally on a device. It accepts JPG, PNG, WebP, GIF, and HEIC files, and converts among JPG, PNG, WebP, and HEIC. Compression can use an adjustable quality setting or a target size such as under 100KB or 1MB. Resizing supports exact pixels, percentages, and presets for Instagram, TikTok, YouTube, Facebook, X, LinkedIn, and Pinterest. A metadata option removes EXIF and GPS details before download. Batch processing is supported, with PNG and ICO export, app icon sets, and web manifest support. MumenLabs says files are processed in the browser, never uploaded, and remain usable offline after loading. The tool works in desktop and mobile browsers without a download, app, plugin, or extension. The Free plan costs nothing, requires no account, and has no watermark, batch limit, size limit, or daily quota; hardware is the practical constraint.
