Plumebox is a small set of image tools built to solve one problem: most online image tools make you upload your photos to someone else's server just to resize or compress them.
Every tool here runs entirely in your browser using standard web technology (the HTML canvas). Your files never leave your device. There's no upload step because there's no server involved in the processing at all.
The site is supported by display ads. There's no account system and no data collection beyond standard, anonymous site analytics.
