IMAGES
Free Image Resizer
Resize images to custom pixel dimensions while preserving aspect ratio.
PNG uses lossless encoding; the quality slider applies to JPG and WebP. JPG replaces transparency with white. Animated images become a single still frame.
Your files and input stay on your device. Their contents are not saved or sent to Analytics.
How to use the image resizer
Choose an image, set the target width or height, and resize it. Keep aspect ratio enabled to avoid stretching.
What to know about the result
Large dimensions are limited to 40 megapixels to protect browser memory. Upscaling does not restore missing detail.
