Compression happens in two steps. First, metadata stripping removes EXIF data, GPS tags, and embedded color profiles - this alone often saves 5-15% with zero visual impact. Second, the quality slider controls the level of lossy compression applied during re-encoding, using the same JPEG/WebP quantization algorithms found in desktop editors like Photoshop.
Because everything runs through a professional-grade image engine compiled to WebAssembly, the compression engine is identical to what you'd get running premium editing software locally on a desktop - it just runs inside your browser tab instead.
Frequently asked questions
5 questionsCompression reduces file size by changing how pixel data is encoded, keeping the same dimensions. Resizing changes the actual pixel dimensions. This tool only compresses - use the Crop & Resize tool if you also want to change dimensions.
