Why resize images?

Resizing images to the right dimensions is essential for website performance, social media posts, and email attachments. Smaller images load faster, take less storage space, and meet platform-specific size requirements.

How does it work?

Upload your image, enter custom dimensions or choose a social media preset, and download the resized version. Everything happens in your browser — your files are never uploaded to any server. The aspect ratio is locked by default to prevent distortion.

Social media image sizes

Each social platform has recommended image sizes. Instagram posts work best at 1080x1080, Facebook shared images at 1200x630, and Twitter posts at 1600x900. Our presets make it easy to resize for any platform.

FAQ

Is the resizing secure?

Absolutely. Your images are resized directly in your browser and are never sent to any server.

Can I resize without losing quality?

Resizing always involves re-encoding. For PNG output, the process is lossless. For JPG and WebP, you can control quality with the slider.

What formats are supported?

You can resize JPG, PNG, and WebP images. You can also change the output format during resizing.

Can I resize to exact dimensions?

Yes, you can enter exact width and height. With aspect ratio locked, the image will fit within your specified dimensions. Unlock it to stretch to exact size.

What is the maximum file size?

You can resize images up to 25 MB for free. With the Pro plan, the limit goes up to 100 MB.
