What is an image compressor?
这是什么
An image compressor is a tool that reduces the file size of an image while keeping it looking sharp. filecompressor.app re-encodes your JPG, PNG, WebP, or AVIF image right in your browser, removing redundant data and tuning quality so the output is dramatically smaller with little to no visible difference.
Unlike upload-based compressors that send your photos to a server, this tool processes everything on your device using WebAssembly. Your images stay completely private, there are no file limits, and you never have to create an account.
How to compress an image
使用方法

- 1
