Resize Image scales a photo to exact pixel dimensions or a common social-media preset, with an optional lock to keep the aspect ratio. It's handled by your browser's Canvas engine, so images resize instantly and privately, and never leave your device.
Drop a JPG, PNG or WebP file in, or click to browse. Its dimensions are read automatically.
Enter a width and height, keep the aspect ratio locked, or pick a preset like Instagram post or YouTube thumbnail.
Choose how the image should fit and export your resized picture.
Enlarging beyond the original can soften detail, but reducing size stays crisp thanks to high-quality resampling.
Yes — leave the lock enabled and changing the width updates the height automatically to avoid stretching.
JPG, PNG, WebP, GIF and BMP are accepted, and the result is saved in the source format.
No. This tool runs entirely in your browser — your file is processed on your own device and never leaves it. The only network request is an anonymous usage counter.
