Image Resizer

Drop an image here or click to choose

Type a new Width and Height, then download a PNG named with those pixel sizes. The picture is redrawn at that size, so making a small photo larger will look soft.

How to use

  1. Drop one image, or click Drop an image here or click to choose. Width and Height fill with the original pixel size. A line under the fields shows Original and those dimensions.
  2. Edit Width or Height. Lock ratio starts checked. With it on, typing one side recalculates the other and rounds to a whole pixel. Uncheck Lock ratio if the two numbers should differ.
  3. Click Download Resized. The file is always a PNG named resized-WIDTHxHEIGHT.png, using the numbers in the fields. A JPG source still downloads as PNG.

When it helps

Use it when a form asks for an exact pixel size, such as 1200 by 630, and the camera file is a different size. Lock ratio keeps the proportions while you type, so a landscape photo does not get stretched into a square by accident. Uncheck it only when you truly want unequal sides.

Download Resized redraws the pixels. It does not offer a format menu. If you need a JPG after the resize, open the Image Converter and choose JPG there. If the new PNG is heavy, the Image Compressor is the page aimed at file size, and it saves compressed.jpg.

Limits

Enlarging a small photo will look soft. The page spreads the pixels that already exist. It does not rebuild detail, and it is not a sharpening tool. Shrinking is usually cleaner than enlarging, but tiny text can still turn muddy.

There is no format choice and no quality slider. The download is PNG even when the source was JPG or WebP. The name is resized plus the width, an x, and the height, ending in .png, not the original filename. One image at a time. An empty or zero side falls back to the original size for that side.

Questions

Why did my JPG download as a PNG?

Download Resized always saves image/png. The source format is not offered as a choice. Convert that PNG on the Image Converter if you need JPG, and expect the white fill that JPG uses.

What does Lock ratio change?

While it is checked, Width updates Height and Height updates Width, using a rounded whole number of the original proportion. Uncheck Lock ratio to type two unrelated numbers.

Will a larger size look sharper?

No. A bigger Width and Height only redraw the same picture onto more pixels. Scale a small file up a lot and the result looks soft. Shrink when you can.
