Resize images with custom dimensions, aspect ratio preservation, and quality settings for web and print.
Everything runs locally in your browser
Images are decoded and redrawn on an HTML canvas on your device. Nothing is uploaded to a server. Enable the aspect ratio lock to scale proportionally, or unlock it to stretch to exact dimensions.
The image resizer changes the pixel dimensions of an image and exports it as PNG, JPEG, or WEBP. Load a picture, enter a new width and height or apply a preset, and download the result. It is useful for fitting an image to an upload limit, generating a thumbnail, or producing a specific size for a social profile or banner.
Resizing happens entirely in your browser. The image is decoded and redrawn on an HTML canvas with high-quality smoothing on your device — nothing is uploaded to a server. You can load PNG, JPEG, WEBP, or GIF files up to 25 MB.
An aspect-ratio lock keeps the image proportional: change the width and the height follows automatically, so the picture never looks stretched. Unlock it to force exact dimensions. Presets cover common sizes like a 150x150 thumbnail, 1080x1080 square, 1280x720 (HD), and 1920x1080 (Full HD), and a side-by-side preview shows the original next to the resized output along with the new file size.
No. The image is decoded and redrawn on an HTML canvas in your browser, so it never leaves your device.
Leave the aspect-ratio lock enabled. When it is on, changing the width updates the height automatically (and vice versa) so the proportions stay intact.
You can export the resized image as PNG, JPEG, or WEBP. For the lossy formats, a quality slider controls the size-versus-detail trade-off.
You can load PNG, JPEG, WEBP, and GIF files up to 25 MB.
Yes, you can set dimensions larger than the original, but upscaling cannot add detail that is not in the source, so the result may look soft.
