Frequently Asked Questions

Why convert to WebP format? ▼

WebP provides superior lossless and lossy compression, typically reducing file size by 25% to 35% compared to PNG and JPEG without perceptible quality loss.

What happens to transparency when converting PNG to JPG? ▼

Since JPEG does not support transparency (alpha channels), transparent pixels are automatically rendered on a clean white background.

Are my photos ever uploaded to a remote server? ▼

Never. All conversions happen entirely in your device GPU/CPU via standard HTML5 Canvas APIs.
