Optimizilla
Optimizilla is a browser-based image compressor for JPEG, PNG, WebP, GIF, and SVG files.
What Optimizilla is
Optimizilla is a browser-based image compressor for JPEG, PNG, WebP, GIF, and SVG files. It lets you adjust image quality and preview the result before saving, and supports batch processing and metadata controls. Compression happens in the browser using WebAssembly; the site says files are not uploaded to its servers and that EXIF, GPS, and camera metadata are removed from compressed images. For JPEGs, it detects original quality from quantization tables and uses a default target quality of 80. PNGs are converted to PNG8 with up to 256 colors while preserving transparency. Animated GIF optimization reduces the color palette while retaining animation frames. The free plan is free, with no registration, daily limits, or watermarks, and allows unlimited compression according to the homepage. The pricing page lists a 25 MB maximum file size and up to 50 files per batch for Free. Pro costs $9 a month and adds unlimited file size and batch uploads, API access, advanced controls, and other tools.
