Can I resize images for social media?

Yes! We have built-in presets for Instagram Post, Instagram Story, Facebook Cover, Twitter Header, YouTube Thumbnail, and HD resolution.

Will resizing affect image quality?

Upscaling may reduce sharpness, but downscaling preserves quality well. Use the aspect ratio lock to prevent distortion.

What file formats can I resize?

You can resize PNG, JPG/JPEG, and WebP images up to 50MB in size.

Will resizing an image reduce its quality?

Downscaling (making smaller) preserves quality well. Upscaling (making larger) may reduce sharpness since new pixels must be interpolated. For AI-powered upscaling, try our Image Upscaler tool.

Does Image Resizer upload my files to a server?

No. All processing happens entirely in your browser. Your files never leave your device, ensuring complete privacy and security.

What is the maximum image size I can resize?

You can resize images up to 50MB in file size. The tool supports PNG, JPG, and WebP formats with no limit on output dimensions.
