Resize Image Online — Free Image Resizer

Oversized photos slow down websites, blow past upload dimension limits on marketplaces and forms, and make for painfully slow email attachments. This tool resizes JPG, PNG, and WebP images to a target width entirely on your device — set the width you need, drop in one image or a batch of them, and each one is scaled down proportionally with a before/after preview so you can confirm the result before downloading. Images already narrower than your target are left untouched, so it's safe to run a whole folder through at once without accidentally blowing up a small image.

Frequently asked questions

How does resizing by width work?
Set a target width and every image you drop in is scaled down to that width, with the height calculated automatically so the picture doesn’t look stretched. If an image is already narrower than your target, it’s left exactly as-is — this tool only ever shrinks, it doesn’t upscale.
Will resizing change my image format?
No, for JPG, PNG, and WebP inputs the output keeps the same format. A handful of formats without a browser-safe re-encoder (GIF, BMP, AVIF) are converted to PNG after resizing, since the pixels have to be re-encoded into something once resized.
Does resizing also compress the file?
Resizing naturally shrinks file size since there are fewer pixels to store, but this tool re-encodes at a high quality setting since its job is dimensions, not squeezing out every extra kilobyte. Use the compress-image tool afterward if you also want maximum compression.
Is there a limit on file size or how many images I can resize?
No — everything happens on your device, so there’s no upload limit or file-count cap to enforce.
Are my images uploaded anywhere?
No. Resizing runs entirely in your browser in a background thread; your files never leave your device.
