FAQ

Frequently Asked Questions

How do you handle transparent areas when converting PNG to BMP?
Since standard BMP files do not support alpha transparency, transparent areas can turn black or distorted in basic converters. Image Studio solves this by letting you choose a custom background fill color—via a color picker, hex code, color name, or RGB values—to seamlessly replace transparent pixels during conversion.
Is my data safe when using this converter?
Absolutely. Unlike other online converters that upload your images to cloud servers, Image Studio processes everything locally in your browser. Your files never leave your device, ensuring total privacy.
Are there any file size limits or conversion caps?
No. Because the tool runs entirely on your local hardware, we do not impose any file size limits, daily conversion caps, or speed throttles. You can convert as many images as your computer can handle.
Can I use hex or RGB codes to select the background color?
Yes! You have complete control over the fill color. You can select it visually with our interactive palette, type in standard color names, or paste exact Hex (#FFFFFF) and RGB (255, 255, 255) codes for pixel-perfect accuracy.
