Frequently Asked Questions (Image Converter)

What is the best format and quality for web images?

WebP and AVIF offer the best compression-to-quality ratio. A quality setting between 80% and 85% is typically the sweet spot, providing significant file size reductions (up to 70-80%) with virtually no human-perceptible loss in visual clarity.

Will image transparency be preserved during conversion?

Transparency is fully preserved when converting to PNG, WEBP, or AVIF formats. If you convert transparent images to JPG (which does not support transparency), the transparent pixels will be filled with your selected background color in Advanced Settings (defaults to white).

Are my images uploaded to any server for processing?

No. All conversion, resizing, and optimizations are performed entirely inside your browser's sandboxed memory using Canvas and WebAssembly. Your images never leave your local device, making this tool completely secure for corporate and sensitive data.

How does the HEIC converter work on Windows/Android?

Apple's HEIC photos are decoded in-browser using a dynamically loaded client-side parser. This allows Windows, Linux, and Android users to convert iPhone photos directly without needing macOS or external cloud upload tools.
