Lock uses the first uploaded image’s aspect ratio. With lock off, leave one side empty to keep aspect on the server.

How to resize an image online

STEP 1

Upload a JPG, PNG, GIF, or other supported image from your device.

STEP 2

Enter the target width and height (or scale) that fits your site, email, or profile requirements.

STEP 3

Click Resize. Download when processing finishes. Each file stays available for up to 5 downloads.

Exact sizes for uploads

Match profile, banner, and product image requirements without opening a desktop editor.

Faster pages and emails

Smaller dimensions usually mean smaller files and quicker loads. Pair with Image Compressor when size still matters.

Works anywhere

Resize images in the browser on Windows, Mac, Linux, or mobile.

When to resize vs crop vs compress

Resize changes overall width and height. Crop removes edges to a new frame. Compress reduces file size with less focus on pixel dimensions. Use resize for upload specs, crop for framing, and compress when the file is still too heavy.

Keep aspect ratio in mind

Stretching to unrelated width and height can distort faces and logos. Prefer proportional scaling when the destination allows it, or crop first to the composition you want, then resize to the final pixel size.

Will resizing reduce image quality?

Downsizing for the web usually looks fine on screens. Enlarging far beyond the original can look soft. Use Image Enlarger when you need a bigger version with care.

Which formats can I resize?

Common formats such as JPG, PNG, and GIF are supported. Resize to the format your destination already expects when possible.

Can I resize multiple images at once?

Yes. Upload a batch within plan limits, apply dimensions, and download the results.

Should I compress after resizing?

Often yes for web and email. Resizing lowers pixel count; compression can shrink the file further for faster uploads.
