Resizing is also one of the most effective ways to reduce file size. A 4000x3000 pixel photo resized to 1200x900 for web use can be 80% smaller. Combined with our compression tool, you can dramatically optimize images for faster load times and better performance.

Image Resizing FAQ

Can I resize images without losing quality?
Downscaling (making images smaller) preserves quality well since the algorithm has more pixel data to work with. Upscaling can introduce some softness, but our tool uses high-quality resampling to minimize this. For best results, avoid upscaling beyond 200% of the original size.
What dimensions can I resize to?
You can set any custom width and height in pixels, or scale by percentage from 10% to 500%. The aspect ratio lock ensures your images are never distorted during resizing.
Which image formats can I resize?
Our image resizer supports JPEG, PNG, and WebP formats. Upload any of these formats and resize them to your exact specifications. The output format matches the input format.
Is there a limit to how many images I can resize?
Free users can resize up to 20 images per day with a 10 MB file size limit. Pro users get unlimited resizing operations and a 25 MB file size limit, plus batch processing to resize multiple images at once.
