SlimPix by Indak

Images never leave your browser

Image & video optimizer

Slim down your assets

Drop JPG, PNG, SVG — or a full-quality video. Get web-ready files back: smaller images in any format, and muted WebM + MP4 hero pairs. Every byte is processed locally in your browser.

Optimization settings

Output format

All formats encodes each image to JPEG, WebP, and AVIF side by side so you can grab whichever file a project needs.

Used when the optimizer is off. PNG is lossless, so this sets effort.

Longest edge in pixels. Leave empty for no resizing.

Download filename
Video preset

Drop a full-quality video and SlimPix outputs the web-ready pair: a lightweight WebM plus an MP4 fallback, muted, with a poster image and a copy-paste HTML snippet.
