Optimizilla
Optimizilla is a web image-compression tool for JPEG, PNG, WebP, GIF, and SVG files. It processes images in the browser, supports batch work, and lets users adjust quality and preview the result before saving. The compressor uses format-specific handling: JPEG quality is inferred from quantization tables with a default target of 80; PNG files become PNG8 with up to 256 colors while preserving transparency; and animated GIF optimization reduces the palette while retaining frames. Compressed images have EXIF, GPS, and camera metadata removed. The site says files are not uploaded to its servers. Its free plan is free, with no registration, daily limit, or watermark, and is described as allowing unlimited compression. The pricing page also lists a 25 MB maximum file size and batches of up to 50 files for Free. Pro costs $9 a month and includes unlimited file size and batch uploads, among other tools. Enterprise pricing is custom and not listed; its plan includes custom integrations, without naming partners.
