About the Resize image tool
A 4000-pixel-wide image for a profile avatar or article thumbnail is pure waste: slower loading and more memory for zero visual benefit. This tool resizes your images two ways — a percentage of the original, or an exact pixel width with the aspect ratio kept automatically — for multiple images at once with the same setting.
A practical rule: always shrink, never enlarge — upscaling a small image adds no detail that isn't there, just blur. Processing stays in your browser with no upload. For maximum size reduction, resize dimensions here, then run the result through the Compress Image tool.

Frequently asked questions
Does the image get distorted when resizing?+
No, the original width-to-height ratio is kept automatically to avoid any distortion.
Can I enlarge an image beyond its original size?+
Yes, but very large upscaling may reduce sharpness since it can't add detail that wasn't in the original.
