Will the image be distorted if I only enter one dimension?

No. If you only enter width or only enter height, the other dimension is calculated automatically to preserve the original aspect ratio. The image won't be stretched or squished.

Can I make an image larger (upscale)?

Yes, but upscaling reduces sharpness since pixels have to be invented. For the best results, always work from the highest resolution original you have.

What's the maximum size I can resize to?

There's no hard limit, but extremely large outputs (e.g. 10,000 × 10,000 px) may take longer to process.

What formats does the resizer support?

JPG, PNG, WebP, and AVIF. The output is returned in the same format as the uploaded image.
