QodeCat Image Resizer is a powerful, free tool that allows you to change the dimensions (width and height) of your photos and reduce their file size without uploading them to a server.
Large images slow down websites. By resizing a 4000px wide photo to 1200px (standard web size), you can reduce the file size by up to 90%, significantly improving page speed and SEO scores.
Platforms like Instagram, LinkedIn, and Twitter have specific dimension limits. Use this tool to crop or resize your visuals to fit perfectly.
Yes. Unlike other sites, QodeCat processes your images strictly inside your web browser. Your photos are never sent to our servers.
Not necessarily. Our algorithm uses 'lossy' compression which removes data that the human eye can barely perceive. Reducing quality to 80% usually saves 50% of file size with no visible difference.
You can input JPG, PNG, and WebP files. You can also convert between these formats (e.g., upload a PNG and download it as a compressed JPG).
