Frequently Asked Questions
1. Will my images be stored on your server?
No, all processing happens directly in your browser. Your images are never uploaded to any server, ensuring complete privacy.
2. What is the maximum image size I can process?
This depends on your device's capabilities, but most modern browsers can handle images up to 10-20 megapixels without issues.
3. Why should I use WEBP format?
WEBP typically provides better compression than JPEG or PNG, meaning smaller file sizes with similar quality, which helps with faster loading times.
4. Can I add text or watermarks to my thumbnails?
This tool focuses on resizing and optimization. For adding text or watermarks, you would need an image editor before using this tool.
5. Will the aspect ratio be maintained when I change dimensions?
Yes, if the "Maintain Aspect Ratio" checkbox is selected, changing one dimension will automatically adjust the other to preserve the original proportions.
