Resize Image — Free, Private, In Your Browser
Change the width and height of your JPG, PNG, WebP, and HEIC images right in your browser. Set a target size, keep the aspect ratio locked or free, and download — nothing is ever uploaded to a server.

JPG, PNG, WebP & HEIC — resized entirely on your device, never uploaded
With aspect ratio locked, set one dimension and each image keeps its proportions. HEIC images are saved as JPG.
Drag your images into the box above (or tap to choose them). Enter a width or height in pixels; with aspect ratio locked, each image keeps its proportions, so a whole batch can be resized to the same width at once. Turn the lock off to set an exact width and height.
Each resized image shows its old and new dimensions and is offered for download. Resize many at once and download them together as a zip. HEIC images are saved as JPG, since browsers cannot write the HEIC format.
Because everything runs locally in your browser, the tool works offline once loaded and none of your images are ever sent anywhere — safe for personal and sensitive photos.
Frequently asked questions
- Are my images uploaded anywhere?
- No. Resizing happens entirely in your browser. Your files never leave your device.
- Which formats can I resize?
- JPG, PNG, WebP, and HEIC. HEIC images are saved as JPG because browsers cannot write the HEIC format.
- How do I keep the aspect ratio?
- Leave "Lock aspect ratio" on and set just one dimension — the other is calculated automatically so the image is not stretched.
- Can I make an image larger?
- Yes. You can enlarge as well as shrink, though enlarging cannot add detail that was not in the original.
