Set a new width and let the height follow, without distorting the picture.
Most pictures on the web are far bigger than the space they appear in, and the visitor pays for the difference.
Type the width you need and the height is worked out from the picture's own proportions, so nothing is squashed or stretched. That is the whole point of resizing by width: a 4000 px photo becomes 1200 px wide and 800 px tall if it started as 3:2, without you calculating either side by hand.
A blog header is happy at 1200 px, a newsletter image at 600 px, a link preview at 1200 × 630. Social posts settle around 1080 px on the long edge. Sending a 12 megapixel photo to any of them only gives the platform something to throw away.
Halving the width and the height of an image removes three quarters of its pixels, and the file shrinks with them. It also looks sharper on screen, because the browser no longer has to shrink a huge image down to fit the layout.
Scaling down is reliable; scaling up is the one thing a resizer cannot honestly do.
Only the width is asked for, and the height follows it, so the proportions of the original always survive. "Fit inside" is the mode that guarantees this: the image is scaled to the width you set, never past it. The other two modes only make a difference when a height is fixed as well, which this form does not ask for.
If you type a width larger than the original, the result stays at the original size. This is deliberate: enlarging interpolates new pixels that were never photographed, so it makes the file heavier and the picture softer at the same time. There is no hidden upscale here.
PNG stays PNG, JPG stays JPG, WebP stays WebP, so every program that opened the first file opens the result. The output format field is there if you want to change it on the same pass — a lighter WebP for a page, a JPG for an email — but leaving it alone is the safe default.
Phone photos often store their rotation as a tag rather than in the pixels; that tag is applied, so a picture that looked sideways in a file list comes out upright with the dimensions swapped to match. Camera details, GPS position and edit history are not written into the resized copy.
Three steps, one field to fill in.
Drag it onto the box, click to browse, or paste it with Ctrl+V (Cmd+V on a Mac). PNG, JPG, WebP, AVIF, GIF and TIFF are accepted, up to 25 MB each. An animated GIF is read as its first frame.
For example 1200 for a blog image, 600 for an email, 1080 for a social post. The height follows automatically and the preview shows the exact pixel dimensions before you commit. Leave the field empty to keep the original size and only re-save the file.
The result line reports both the new dimensions and the weight, next to the original, so the saving is visible immediately. One click saves the file under its own name; the original on your device stays as it was.
Choose the target size once and take it from the biggest copy you have.
Shrinking a 4000 px photo to 1200 px gives a clean result; enlarging a 600 px copy to 1200 px gives a soft one. Always resize from the biggest version you still have, and keep that file — every future size should come from it, not from the last resized copy.
A picture shown 600 CSS pixels wide wants about 1200 real pixels on a modern phone or laptop display, otherwise it looks slightly blurry. Doubling the display width is the usual compromise: sharp on high-density screens, still reasonable in weight.
Pixels you removed never have to be encoded, so resizing first gives the best result from compression and from a format change in the image converter. For a vector source there is nothing to resize at all — render it at the right size with SVG to PNG and the edges stay perfectly sharp.
Yes. There is no account, no trial, no credit card and no watermark, and you can resize as many images as you like. A short rate limit keeps the service responsive for other visitors.
Yes. You give the width and the height is calculated from the original proportions, so a 3:2 photo stays 3:2 at any width. Choose a width and the picture is scaled, never squashed — which is why the distorted look of a stretched image cannot happen here.
Not with this tool, and that is on purpose. Typing a width larger than the original leaves the image at its own size, because enlarging adds invented pixels: the file grows, the detail does not. If you need a larger version, go back to the source — a bigger original or a vector file rendered at the size you want.
Up to 25 MB per file and 50 megapixels as an image, with a maximum width of 8000 px for the result. If a file is refused for size, it is usually a scan or a very high-resolution photo — resize the copy you already have, or export a smaller version from the original.
Files are processed on our server and not stored. The image is decoded, resized and sent back to your browser in one pass.
