Resize Image

Resize JPG, PNG, or WebP to a target width and/or height. Aspect ratio is preserved when only one dimension is set.

100% in your browser. Files never uploaded.

How to use

1
Drop your image
JPG, PNG, or WebP. We'll show its current dimensions.
2
Set width or height
Leave one blank to preserve aspect ratio. Set both to stretch.
3
Pick output format and quality
JPEG/WebP have a quality slider. PNG is lossless.
4
Click Resize
Re-encoded entirely in your browser via canvas.

Can I upscale an image?

Yes, but it won't add detail — pixels are interpolated. For real upscaling, you'd need an AI tool.

Are images uploaded?

No. All resizing happens locally via the Canvas API.
