What is NanoImage?
NanoImage is a free suite of privacy-first image tools that run 100% in your browser — compress, resize, crop, convert, edit, and on-device AI — with no upload, no account, and no server-side processing of your files.
Anyone who needs everyday image tasks can open a tool, process the file locally with JavaScript and the Canvas API, then download the result. You can verify privacy in DevTools → Network: no outbound image upload occurs during processing. NanoImage is built for people who want TinyPNG-style convenience without sending photos to a cloud.

Sources & further reading
Images remain the predominant resource type on homepages (excluding video): the median desktop page requests about 1,054 KB of images, and the median mobile page about 900 KB.
EXIF metadata can include GPS coordinates, device identifiers, and capture timestamps — information many people do not intend to publish when they share a photo online.
Browser-local image tooling keeps originals on-device: processing with the Canvas API never requires uploading the file to a remote editor.
