Frequently Asked Questions

Are my images uploaded to a server?

No. All conversion and resizing is performed entirely in your browser using the Canvas API. Your images never leave your device, making this safe for sensitive or private files.

Why does JPEG not support transparency?

The JPEG format does not support alpha channels. When converting from PNG to JPEG, transparent areas are filled with a white background automatically. If you need transparency, use PNG or WebP instead.

What quality setting should I use?

For web use, 80% quality is a good balance between file size and visual fidelity. For photographs where detail matters, try 90–95%. For thumbnails or previews, 60–70% can significantly reduce file size.
