Frequently asked questions
Are my images uploaded to a server?
No. Every tool on this site runs entirely in your browser using the HTML canvas. Your images never leave your device, which also makes processing instant — there is no upload or download wait.
Will my resized image look blurry?
This tool uses Lanczos resampling (via the pica library), the same high-quality filter used by professional editors. Downscaled images stay crisp; upscaling beyond the original size will always soften somewhat because new pixels have to be invented.
Can I resize without keeping the aspect ratio?
Yes — toggle the aspect lock off to set width and height independently. The image will stretch to your exact dimensions.
