How do I resize an image online?

Upload your image, enter the desired width and height in pixels (or use a percentage scale), and click Process. The resized image downloads instantly. No signup or software installation required.

Can I resize an image without losing quality?

Yes. Downscaling preserves sharpness because the algorithm averages pixels. Upscaling above the original resolution can reduce perceived sharpness, so we recommend using the "Don't enlarge" option to prevent accidental upscaling.

What image formats are supported?

You can resize JPG, JPEG, PNG, WebP, and HEIC images. iPhone HEIC photos are automatically converted before resizing.

Can I resize multiple images at once?

Yes. Upload multiple images and each will be resized to the same dimensions in a batch. All results can be downloaded individually or as a ZIP.

Is resizing done on your server?

No. All resizing happens entirely using the Canvas API. Your images are processed securely.

Can I resize by percentage instead of pixels?

Yes. Select the percentage mode and enter a value like 50% to halve the dimensions, or 200% to double them. Aspect ratio is always preserved in percentage mode.
