Which format should I choose?

WebP and AVIF offer the best compression for websites. PNG is ideal for transparent graphics and logos. JPG is universally compatible. BMP provides raw uncompressed bitmaps, and ICO generates desktop/web icon files.

Are BMP and ICO files truly converted?

Yes. Quick4Media uses custom binary encoders that generate valid 24-bit Windows BMP files and 32-bit ICO icon files directly in browser memory.

Does it support transparency?

Yes, when converting to PNG, WebP, AVIF, or ICO, transparent alpha channels are preserved. When converting to JPG or BMP, transparency is seamlessly blended onto a clean white background.
