Why Use It
FAQ
How do I resize an image without distorting it?
Keep "Lock aspect ratio" enabled so width and height scale together proportionally. This prevents the image from looking stretched or squashed.
What size should I resize my image to for Instagram?
Instagram recommends 1080×1080px for square posts and 1080×1350px for portrait posts. Use the built-in presets to apply these sizes instantly.
Does resizing an image reduce its quality?
Making an image smaller rarely causes visible quality loss. Making an image larger than its original resolution can introduce softness. For enlarging, try the upscale tool instead, which is built for that.
Can I resize an image by percentage instead of pixels?
Yes. Switch to percentage mode and drag the scale slider to shrink or enlarge the image relative to its original size, with target pixel dimensions shown live.

The right dimensions for every platform
Every platform expects different image dimensions — a website hero banner, an Instagram post, a YouTube thumbnail, and a printed flyer all have different ideal pixel sizes. Uploading an image that's the wrong size often means the platform crops or stretches it for you, which can cut off important parts of the photo or leave it looking blurry.
This resize tool lets you set exact width and height values, scale proportionally by percentage, or pick from built-in presets for the most common social media and web sizes. The aspect ratio lock keeps your subject looking natural by preventing horizontal or vertical stretching, which is the most common mistake people make when resizing manually.
Because resizing happens on the Canvas element directly in your browser, there's no upload delay and the live preview shows exactly what you'll get before you download. It works equally well for shrinking a large camera photo down for the web or enlarging a small graphic slightly for a specific layout.
