What happens if I don't maintain the aspect ratio?

The image will be stretched to fill the target dimensions, which can make it look distorted. For most use cases, you should keep 'Maintain aspect ratio' enabled. If you need a specific aspect ratio, use the Image Cropper instead.

Can I make an image larger?

Yes, but the quality will not improve. Enlarging an image beyond its original dimensions produces a blurry result because the tool can't create detail that isn't in the source. For best results, start with the highest-resolution source image available.

What's the maximum size I can resize to?

The practical limit is about 10000×10000 pixels, which is the canvas size limit in most browsers. Very large outputs may fail on low-memory devices.

Does resizing affect image quality?

Downscaling (making an image smaller) preserves quality well. Upscaling (making an image larger) reduces apparent sharpness. The tool uses bilinear interpolation, which produces smooth results for most use cases.

About Image Resizer

The Image Resizer lets you change the dimensions of an image — either to specific pixel dimensions or by a percentage scale. This is useful for creating thumbnails, fitting images into specific layout slots, reducing image resolution for faster loading, or preparing images for social media profiles and posts. The resizer runs entirely in your browser using the Canvas API, so your images stay private. You can choose to maintain the aspect ratio (which prevents distortion) or resize freely. The output preserves the original format, and you can choose the quality level for JPG and WebP output.

Privacy

All resizing happens in your browser using the Canvas API. No image is uploaded to any server.

Limitations

Upscaling beyond 2× the original size produces visibly blurry results. Maximum output size is about 10000×10000 pixels.
