PNG → BMP

Learn about the formats: What is PNG? What is BMP?

Convert PNG to BMP effortlessly with our fast online tool. This conversion is essential for legacy systems, specific software, and raw uncompressed graphic workflows.

Both PNG and BMP are raster image formats, but they handle data quite differently. PNG uses efficient lossless compression to keep file sizes manageable while supporting transparency. BMP, developed by Microsoft, stores pixel data with little to no compression. When you convert PNG to BMP, the image structure is unpacked, resulting in a much larger uncompressed file ready for immediate reading by older Windows applications.

Because both are raster image formats and the conversion is strictly lossless, your image quality is preserved 100% without any compression artifacts.

Tips

Ensure your hard drive has enough free space, as BMP files are significantly larger than PNG files.
Remember that standard BMP does not support alpha channel transparency, so transparent areas in your PNG will typically be filled with a solid background color like white.
Use this conversion only when specific software explicitly requires BMP format.

Common use cases

Importing graphics into legacy Windows software that only accepts uncompressed BMP files.
Preparing textures or assets for older game engines requiring raw bitmap inputs.
Setting custom system wallpapers in legacy operating systems.

Why ConvertX stays free — forever

We built this project so anyone can convert files without paywalls, accounts, or hidden limits. Here is what that promise means in practice.

🎁

Free tools today — and always

Every converter on ConvertX is free to use: no trials, no premium tiers, and no credit packs. We will never put core conversion features behind a subscription. Whether you convert one photo or a hundred files a week, the price stays zero.

🔒

Privacy-first processing

Many image, audio, and video conversions run entirely in your browser. Your files never leave your device for those jobs. When server processing is required for documents or specialized formats, uploads are handled securely and removed automatically — typically within one hour.

🖼️

Images

Raster and vector graphics for web, print, and photography.

Common extensions: PNG, JPG, WebP, AVIF, GIF, SVG, HEIC, TIFF

Advantages

+ WebP and AVIF offer excellent compression for the web
+ PNG keeps transparency and sharp edges
+ SVG scales without quality loss

Disadvantages

− RAW and TIFF files are large and slow to share
− JPEG loses quality on every re-save
− Some formats are not supported in older browsers

📄

Documents

Office files, PDFs, ebooks, and plain text.

Common extensions: PDF, DOCX, XLSX, PPTX, ODT, EPUB, TXT

Advantages

+ PDF locks layout for printing and sharing
+ DOCX and ODT are easy to edit collaboratively
+ Plain text works on any device

Disadvantages

− PDF is hard to edit without special tools
− Complex layouts may shift after conversion
− Scanned PDFs need OCR for editable text

🎬

Video

Clips, streams, screen recordings, and movies.

Common extensions: MP4, WebM, MOV, MKV, AVI, MPEG

Advantages

+ MP4 (H.264/H.265) plays almost everywhere
+ WebM is efficient for web embedding
+ MKV can hold multiple audio and subtitle tracks

Disadvantages

− High-resolution video needs lots of storage and bandwidth
− Re-encoding always takes time and may reduce quality
− Some codecs require licensing for commercial use

🎵

Audio

Music, podcasts, voice recordings, and sound effects.

Common extensions: MP3, WAV, FLAC, OGG, AAC, M4A, OPUS

Advantages

+ FLAC and WAV preserve full quality for editing
+ MP3 and AAC are universally compatible
+ OPUS delivers great quality at low bitrates

Disadvantages

− Uncompressed WAV files are very large
− Lossy formats cannot be restored to original quality
− DRM-protected files may not convert

Frequently asked questions

No. Both PNG and BMP are lossless raster formats, meaning the visual quality remains completely intact during conversion.

PNG uses advanced compression algorithms to reduce file size, whereas BMP stores raw uncompressed pixel data, causing the file to expand significantly.

Standard BMP format does not support transparency. Transparent pixels in your PNG will be converted into a solid background color.
