FAQ
If you export as PNG, we use lossless compression which preserves image quality perfectly. For JPG or WebP, you can adjust the quality slider to find the perfect balance between quality and file size.
Yes. Keep the "Keep aspect ratio" option checked, and when you input either width or height, the other dimension will automatically update to preserve the original proportion.
Contain scales the image to fit inside the target area, showing the entire image and leaving space if ratios don't match. Cover scales the image to fill the target area, cropping any excess parts. Stretch ignores the aspect ratio and forces the image to match the exact width and height.
We support PNG, JPG, JPEG, and WebP formats for both input and output.
No. Resizing runs in your browser and your image is never sent to our servers.
