Frequently Asked Questions

Why convert BMP to PNG?

BMP (Bitmap Image File) uses uncompressed encoding and is best for legacy software compatibility, raw pixel data transfers, and simple image processing tasks. PNG (Portable Network Graphics) uses lossless encoding and excels at graphics with sharp edges, text overlays, screenshots, and images requiring transparent backgrounds. Converting between them lets you take advantage of each format's strengths — for example, using a compressed format for sharing and a lossless format for editing. All conversion happens locally in your browser with no file size limits.

What does BMP to PNG do?

Convert BMP images to PNG format in your browser. Lossless, private, and completely free — no uploads needed.

Should I keep the original BMP files?

Yes — archive BMP originals before batch-converting. Re-converting from PNG back to BMP never restores discarded data.

How long does BMP-to-PNG conversion take?

Seconds for typical files on a modern device; large files scale with size and CPU. Conversion speed depends on the machine, not the formats — close heavy tabs for big batches.

Will converting BMP lose quality?

From uncompressed to lossless: quality is preserved as far as the formats allow.
