Frequently Asked Questions
What image formats are supported?
The tool supports all common image formats including PNG, JPEG, JPG, WebP, and GIF. You can resize any of these and export to PNG, JPEG, or WebP format.
Will resizing reduce image quality?
When enlarging images, some quality loss is inevitable. When reducing size, our high-quality smoothing algorithms minimize quality loss. For JPEG and WebP, you can adjust the quality slider to balance file size and image quality.
What is aspect ratio, and should I maintain it?
Aspect ratio is the proportional relationship between width and height. Maintaining it prevents image distortion. Disable it only if you intentionally want to stretch or compress the image.
Is there a file size limit?
Yes, the maximum file size is 100MB. This limit ensures smooth processing in your browser without performance issues.
Are my images uploaded to your servers?
No! All image processing happens entirely in your browser using JavaScript and the HTML5 Canvas API. Your images never leave your device, ensuring complete privacy.
