Resize Images Online — Free, No Upload Required

Resize handles the opposite problem from crop: same image, different dimensions, without cutting anything out. Set target width and height, or scale by percentage, and the tool handles the math — including keeping proportions locked so nothing looks stretched.

Most resizing needs come from a size limit somewhere else: a form that rejects anything over 2MB or wider than 1000px, an email attachment cap, a platform’s upload spec. This tool is built around hitting those targets fast rather than around creative editing.

How to use it

Upload the image, then either type exact pixel dimensions, drag a percentage slider, or pick a common preset (like “1080px wide” or “50%”). Toggle “lock aspect ratio” on to avoid distortion, or off if you deliberately want a different shape. Preview updates live, then export.

FAQ

Will resizing down hurt quality?

Shrinking an image is generally safe — you lose some fine detail but there’s no visible artifacting. Resizing up (enlarging) is where quality drops, since the tool has to invent pixels that weren’t there.

What’s the difference between this and Compress?

Resize changes dimensions (pixel width/height); Compress keeps dimensions the same but reduces file size through encoding. Often you’ll want both — resize first, then compress.

Can I resize a batch of images at once?

Currently this handles one image per pass; for renaming a batch afterward, Batch rename can help organize the output.

Does it support resizing by file size target (e.g. “under 500KB”) instead of pixels?

Not directly — for a size-target workflow, pair this with Compress, which lets you dial in toward a target file size.

What happens to transparency (PNG) when I resize?

It’s preserved — resizing doesn’t flatten or fill transparent areas.
