Frequently Asked Questions
Are my images uploaded to a server?
No, all image processing happens entirely in your browser. Your images never leave your device, ensuring complete privacy.
What image formats are supported?
You can upload JPG, PNG, GIF, and WebP images. You can export as JPG, PNG, or WebP format.
What does "maintain aspect ratio" mean?
When enabled, changing the width automatically adjusts the height (and vice versa) to keep the image proportions the same, preventing distortion.
What is WebP format?
WebP is a modern image format that provides superior compression compared to JPG and PNG, resulting in smaller file sizes with similar quality. It's supported by all modern browsers.
Is there a file size limit?
The limit depends on your browser and device memory. Most modern browsers can handle images up to 50MB, but very large images may be slow to process.
