Resize Image
Resize one or many images by exact pixels or by percentage while keeping the aspect ratio. High-quality downscaling, optional WebP or PNG output and batch

Change the pixel dimensions of a picture: set an exact width and height, scale by a percentage, or fit the image into a maximum box while keeping its proportions. The preview shows the resulting dimensions and file size before you download.
Resizing is different from compressing: this tool changes how many pixels the image has, which is what you need for a website slot of a fixed width, for an avatar with a size limit, or to bring a huge phone photo down to something sensible. Upscaling is possible but cannot add detail that was never captured.

FAQ
Will resizing distort my image?
Not if you keep the aspect ratio locked, which is the default. Unlock it only when you deliberately need a different shape.
Can I enlarge a small image?
Yes, but enlarging cannot create detail - the result is a bigger, softer picture. For print, start from the largest original you have.
What size should I use for the web?
Match the largest width the image will be displayed at, doubled for high-density screens: 1600 px covers most full-width layouts, 800 px is plenty for a card.
Which formats can I output?
JPEG, PNG and WebP, so you can also change the format while resizing.
Can I resize several images at once?
Yes, select a batch and every image gets the same target dimensions.
Are my images uploaded?
No, resizing happens in your browser.

How much quality you actually lose
Lossy compression throws away detail your eye is least likely to notice - first fine texture, then edges. In practice most photographs look identical to the original down to roughly 75-80% quality, and differences only become obvious around faces, hair, foliage, fabric patterns and text. That is why a portrait and a screenshot need different settings: a face at 60% shows blotchy skin where a landscape at 60% still looks fine. Resizing matters more than quality for perceived sharpness: halving the pixel dimensions usually saves far more than dropping quality from 90 to 60, and the result looks better. If you need a specific file size, reduce dimensions first, then quality, and stop as soon as you hit the target rather than going lower than necessary.
Getting a file under a size limit
Upload forms often demand something like "under 2 MB" or "under 500 KB", and the fastest way to get there is to work in the right order: crop away what you do not need, then reduce the pixel dimensions to roughly what the final use requires (1920 px wide is plenty for a full-screen web image, 1000 px for a blog post), and only then lower the quality. Converting to WebP or AVIF can be the single largest saving if the upload form accepts it. Stripping metadata is harmless for size and can matter for privacy, since photos often carry GPS coordinates, the exact camera model and the date. If a form still refuses the file, check whether it imposes a pixel-dimension limit rather than only a size limit - that catches people out more often than actual megabytes.
