Private by design
The image is processed by your browser using the HTML canvas, so it never leaves your device. That makes it safe for client photos, ID-free product shots and anything you would rather not upload to a random website.

Frequently Asked Questions
Is this image resizer free?
Yes. It is free with no sign-up, and images never leave your device.
Will resizing reduce quality?
Making an image smaller keeps it sharp. Making it bigger than the original can make it blurry.
What does crop to fill mean?
The image fills the whole size and extra edges are trimmed from the centre. Fit inside keeps the whole image and adds a background.
Which format should I choose?
JPG or WebP for photos, PNG for graphics with transparency or sharp text.
