Chittu

Compress, convert and resize the images on any page, a whole site, or a local folder. Processed in this browser. Nothing uploaded.

Make the images on a page smaller without sending them anywhere. Chittu compresses, converts and resizes images in bulk, right in your browser. Open it on any page and it lists every image with its size and how much you can save. Pick the ones you want, press Compress, and save them as separate files or one ZIP. Three ways to start - This page: every image on the page you are looking at. - Whole site: Chittu reads the site's pages one at a time, at a slow and steady rate, respects robots.txt and stops at the page cap you set. - Local folder: pick files or a folder from your computer. What it does - Three presets: Smallest, Balanced and Best. Or set your own quality, or a target file size. - Convert to JPEG, PNG, WebP or AVIF, or keep the original format. - Resize by width, height, longest edge or percentage, or to an exact size such as 1080 × 1080 with a centred crop. Images are never enlarged. - A file is never made larger by compression. If Chittu cannot make it smaller, you get the original back, marked "Kept". - The colour profile and the photo's orientation are always kept. Camera details, location and comments are removed only if you ask. - Transparent images going to JPEG: you choose the background colour. Privacy Images are read from the site you are scanning, or from your own disk, and processed on your device. Nothing is uploaded. There is no Chittu server, no account, no analytics and no ads. Chittu asks for access one website at a time, only when a scan needs it, never at install. Free, with no limit on how many images you process.
