About Image Resizing

Image resizing changes the pixel dimensions of your images. This is useful for preparing images for websites, social media, email attachments, or print. Our tool uses high-quality resampling algorithms to maintain image sharpness.

Resize Modes

  • By Percentage: Scale your image proportionally. 50% makes the image half its original size, 200% doubles it.
  • By Dimensions: Specify exact width and/or height in pixels. Enable aspect ratio lock to prevent distortion.

Supported Formats

This tool supports PNG, JPG/JPEG, WebP, AVIF, GIF, BMP, TIFF, HEIC/HEIF, and JPEG XL images. You can also convert between formats during resize by selecting a different output format. HEIC, TIFF, and JXL files are decoded server-side for broad browser compatibility, while most other formats are processed entirely in your browser.
