How to use

How to resize images to exact dimensions in the browser

  1. 1 Upload a photo, screenshot, logo, or graphic by dragging it into the drop area or browsing from your device.
  2. 2 Review the original dimensions and choose a custom width and height or tap one of the preset sizes for a quick starting point.
  3. 3 Keep aspect ratio locked when you want proportional scaling, or unlock it when you need an exact canvas size such as 300 by 300 pixels.
  4. 4 Choose the output format and quality level before resizing so you can balance sharpness, transparency, and file size.
  5. 5 Generate the resized preview, compare the before and after file details, and download the result when it looks right.

An image resizer is one of the most practical browser tools because so many websites, marketplaces, and apps require exact dimensions. Instead of opening editing software for a simple resize, you can upload an image, type the target width and height, and generate a new file in seconds. That is useful for avatars, social posts, product thumbnails, document uploads, and presentation assets.

Support for JPEG, PNG, and WebP output makes the tool flexible for different goals. JPEG and WebP work well when you want smaller file sizes, while PNG is helpful for logos and graphics that need lossless quality or transparency. Keeping the whole workflow client-side also means you can resize images quickly without relying on an external service.
