About Image Resizer

Resize images online for free. Change dimensions, scale by percentage, or use preset sizes for social media.

Resize your images quickly and easily with our free online Image Resizer. Whether you need to adjust dimensions for a website, reduce file size for email, or prepare photos for social media, our tool gives you precise control. You can define exact pixel dimensions or scale by percentage.

Unlike simple resizing tools, ours maintains the aspect ratio to prevent distortion and uses high-quality resampling algorithms to keep your images sharp. It's the perfect first step before using our Image Compressor to optimize for the web.

We also offer preset sizes for all major social media platforms including Instagram, Facebook, Twitter, and LinkedIn. Just select your target platform and we'll handle the rest. If you need to crop the image instead, try our Image Cropper.
