Result
Choose an image and select Resize image. The result will appear here.
How to use
- Choose an image from your device or drag it into the upload area.
- Enter the new width or height. Keep the aspect ratio lock on to avoid stretching.
- Pick an output format and quality if you want to change them.
- Select Resize image, check the preview and download the result.
Supported formats and limits
- Input: JPG, PNG and WebP images up to 25 MB.
- Output: JPG, PNG or WebP, with a maximum of 8000 pixels on each side and 16 megapixels in total.
- Photos taken on phones are rotated correctly using their orientation data.
- Metadata such as camera details and location is not kept in the resized file.
Privacy
- Your image is processed in your browser. It is not uploaded to a server.
- No account is required.
Troubleshooting
- If the image does not open, make sure it is a valid JPG, PNG or WebP file.
- JPG does not support transparency, so transparent areas become white when you convert a PNG or WebP to JPG.
- If the output is larger than the original, reduce the dimensions or lower the quality.
- If a format is unavailable in your browser, choose a different output format.
