How to Resize Images Without Uploading Them

Resize lightweight image assets locally in the browser without routing them through a remote service.

Local image workflows improve trust

For many people, the best image resizer is one that does not require an upload at all. Local processing keeps the interaction simpler and more privacy-friendly.

Resize for the target use case

A blog thumbnail, product image, and support attachment all benefit from lighter files. A simple width-based resize handles a surprising number of those jobs.

FAQ

Does the image leave my browser?
