# ImageTool.app

> ImageTool.app offers free online image compression with lossless support for JPG, PNG, GIF and SVG. Everything runs locally — no upload required.

ImageTool.app provides two ways to compress images, both processing files locally so that image data is never uploaded to a server:

- **Online compressor** — runs locally in the browser, no install, no upload.
- **ImgZilla** — a native macOS app for batch, in-place compression of local files.

Every page below is also available in 17 languages via a URL prefix (e.g. /ja/faq, /de/faq): zh, zh-Hant, en, ja, ko, de, fr, es, it, pt-BR, nl, pl, ru, sv, da, tr, vi.
