Free Image Resizer

Scaling an image down preserves quality well. Scaling up (enlarging) may make the image appear soft or pixelated since no new pixel information is added. For enlarging, use an AI upscaler instead.

No. Resizing happens entirely in your browser using the Canvas API. Your image never leaves your device.

You can upload PNG, JPG, WEBP, AVIF, GIF, and BMP. The resized image is downloaded as PNG by default to preserve quality.

When the lock is enabled, changing the width automatically updates the height (and vice versa) to keep the original proportions. Disable it to set any width and height independently.
