Frequently Asked Questions
Direct answers about formats, alpha channels, and local processing.
How do I convert WebP images to PNG without losing transparency?
Drop your WebP file into the converter and set the target format to PNG. Because the conversion is performed in your browser using native hardware-accelerated 2D Canvas rendering, the full alpha transparency channel is preserved without artifacting, and the file never leaves your computer.
How does the in-browser .ICO Favicon generator work?
When you select ICO as your target format, our lightweight binary encoder creates a multi-resolution Windows ICO file containing 16x16, 32x32, and 48x48 mipmaps. This ensures your website favicon displays cleanly across all high-DPI browser tabs, bookmarks, and desktop shortcuts.
Why do transparent images turn black when converted to JPG?
JPEG and standard BMP formats do not support alpha transparency channels. When converted without padding, browsers default transparent pixels to solid black. EliteBulletin solves this by letting you choose a background fill color (white by default, black, or custom hex) to ensure a clean, professional finish.
Are my images uploaded to any server or saved anywhere?
No. EliteBulletin tools strictly adhere to our Zero-Egress Privacy Pledge. All conversions, decoding, and ZIP archiving take place 100% inside your browser's local RAM. No files, logs, or analytics are ever transmitted to any remote server.
