About this tool
Images straight from a camera or design tool are often far larger than any website or form actually needs, which slows down pages and wastes bandwidth. This tool resizes images either by an exact target width (with height calculated automatically if aspect ratio is locked) or by a percentage of the original size, and supports resizing multiple images in one batch. Locking the aspect ratio prevents accidental stretching or squashing; unlocking it lets you set exact width and height independently when you need a specific fixed size, such as for a profile picture or thumbnail grid. All resizing happens using your browser's own canvas rendering, so nothing is uploaded before you download the result.
Frequently asked questions
Will resizing stretch or distort my image?
Not if aspect ratio lock is enabled — height is calculated automatically from width to preserve the original proportions. Unlock it only if you intentionally want a different ratio.
Can I resize by percentage instead of exact pixels?
Yes — you can choose to scale by a percentage of the original dimensions, or set an exact target width.
Can I resize multiple images at once?
Yes, batch resizing is supported for multiple files with the same settings applied to each.
Does resizing reduce file size too?
Usually yes, since fewer pixels generally means a smaller file, but if you need aggressive size reduction independent of dimensions, pair this with the Image Compressor.
What image formats can I resize?
JPEG, PNG, and WebP are all supported as both input and output.
