Frequently Asked Questions

What quality should I use?

85 is excellent for most uses. 95+ for professional quality. 70-80 for web. Below 60 shows visible artifacts.

Will transparency be preserved?

No. JPEG doesn't support transparency. Transparent areas become white.

What JPEG quality should I use?

Quality 80-85 is ideal for web photos - virtually indistinguishable from 100 but 60-70% smaller. For print, use 95-100. For thumbnails or previews, 60-70 is fine.

Does converting PNG to JPEG lose transparency?

Yes, JPEG doesn't support transparency. Transparent areas will be replaced with a white background. If you need transparency, use PNG or WebP instead.

Privacy & Security

This tool uses wasm-vips (libvips compiled to WebAssembly). The WASM binary (~5MB) is downloaded on first use and cached by your browser. All image processing happens locally on your device - your images are never uploaded to any server. This makes it safe for sensitive, private, or confidential images.
