Resize images to exact pixel dimensions.
Prepare images for articles, profile pictures, and presentations. Keep the original aspect ratio or enter independent dimensions.
Resize a large photograph to a practical size for its intended display area. Consider whether the destination uses high-density screens, then compare the resized preview against the original rather than making every upload as small as possible.
Create an image that meets an application's pixel limits. With aspect ratio enabled, adjusting one dimension calculates the other. If the destination requires a different shape, resizing alone may stretch the image; crop it in an image editor first.
Enlarging a small image may make it blurry. Dimensions are limited to 10,000 pixels and 40 million total pixels to protect browser memory.
A 1920 × 1080 image resized to a width of 1280 with aspect ratio enabled.
A 1280 × 720 image.
Both dimensions are scaled by the same proportion. The resulting height is rounded to a whole number of pixels.
Keep the aspect ratio checkbox enabled. If you enter independent width and height values with it disabled, the image is scaled to that rectangle even when it differs from the original shape.
Use positive whole pixels up to 10,000 per dimension, with no more than 40 million pixels in total. Smaller output dimensions also reduce browser memory requirements.
A little clarity before you get started.
Yes. Keep the aspect ratio option enabled.
Yes, within the tool's dimension limits. Enlarging creates more pixels but cannot restore missing detail, so a small source can look soft or pixelated when scaled up.
No. The complete image is scaled to the requested rectangle. Use an image editor to crop unwanted areas or change the composition before resizing.
It links width and height using the source image's proportions. Changing either field recalculates the other to help prevent stretching.
Not always. File size also depends on output format, image content, and export quality. Compare the generated size, especially when switching between formats.
No. This tool is free to use without signing in. An account lets you keep a list of favorite tools.
Yes, with a current browser. File support, download behavior, and available memory vary by device. For large documents and images, a computer is often more comfortable.
