How it works

- Enter the desired width and height in pixels.
- Toggle the 'Maintain aspect ratio' option to prevent distortion.
- Click Resize, then download the output image.
Example use cases
- Twitter profile photo: Resize any photo to 400 × 400 px for a sharp Twitter/X profile picture that fits the platform's display.
- Email banner: Resize a landscape photo to 600 × 200 px for a standard email header banner without cropping.
Frequently asked questions
Will resizing affect image quality?
Downscaling typically preserves quality. Upscaling beyond the original resolution adds pixels by interpolation and can make the image appear blurry.
What file formats are supported?
You can upload most common image formats (JPEG, PNG, WebP, GIF). The output is always downloaded as a PNG file.
