Are my images secure when using the resizer?

Absolutely. ToolsCrush works entirely offline on the client-side. The image is processed locally in your browser memory using HTML5 Canvas APIs. Your photo is never uploaded to any server.

What is the difference between pixel and percentage resizing?

Resizing by pixels lets you input exact target width and height dimensions (e.g. 1920x1080), while percentage resizing scales the image proportionally (e.g., shrinking it by 50% or enlarging it by 150%).

Does this tool preserve the image quality?

Yes, we use advanced high-quality canvas downscaling filters to minimize artifacts. You can also export your resized image in high-quality WebP, PNG, or JPG formats.
