PNG File

File extension	.PNG
Category	Image File
Description	PNG images provide lossless compression, that is why the quality of the picture is nice, but the size of the file is huge. Because of it this file format is used by photographers. PNG may have several layers of transparency and even include short text descriptions which help search engines to examine the file. Although PNG was developed to replace GIF and partly other formats, it doesn’t support animation since it can’t contain several images like GIF.

BMP File

File extension	.BMP, .RLE, .DIB
Category	Image File
Description	May be the simplest file format, BMP was developed jointly by Microsoft and IBM. That is why it is widespread on Windows platform. This extension is characterized a raster graphic format which is recognized by many programs today. In comparison with other bitmap formats, JPEG and GIF, BMP keeps color data for each pixel in the image and doesn't compress images to decrease a file size. That is what makes it perfect file format for printable images.

Our embedded display controller only accepts 24-bit BMP images, and all our UI assets are PNG. Converting the full icon set to BMP in one batch meant we could update the firmware package without touching each file manually.

I needed BMP versions of PNG graphics for a Windows CE device that has no PNG decoder. The converter produced files that loaded on the device immediately — no color shifts or sizing issues.

Windows Paint on our older lab computers can't open PNG directly, so we convert graphics to BMP first. This converter handles the job in seconds and the files open and edit exactly as expected.

PNG to BMP Converter — Frequently Asked Questions ▼

Why would I convert PNG to BMP?

The most common reason is a requirement from legacy software, game modding tools, industrial systems, or hardware that only accepts BMP as input. BMP is Microsoft's native bitmap format with maximum Windows compatibility. If the target application accepts both PNG and BMP, PNG is almost always the better choice — smaller files, full alpha channel, universal support.

How do I convert PNG to BMP online?

Upload your .png file to the CoolUtils converter. The converter decompresses the PNG pixel data and writes it to the BMP container format — a file header, a DIB header with image dimensions and bit depth, and raw pixel rows padded to 4-byte boundaries. Download the .bmp when done.

Does converting PNG to BMP lose quality?

No. Both PNG and BMP store pixel data losslessly. The output BMP is a pixel-identical copy of the PNG. The only exception: if your PNG has transparency (alpha channel) and you output 24-bit BMP, the transparency is composited against a white background because 24-bit BMP has no alpha channel. 32-bit BMP output preserves the alpha channel.

Is transparency preserved in PNG to BMP conversion?

Partially. 32-bit BMP supports an alpha channel and preserves PNG transparency fully. Standard 24-bit BMP does not support transparency — the converter composites the transparent areas against a white background. If the target application requires transparency support, confirm it accepts 32-bit BMP.

What is the difference between PNG and BMP?

PNG uses DEFLATE lossless compression and is 40–80% smaller than BMP for typical images. BMP stores raw uncompressed pixel data — larger files but simpler structure that any Windows application can read without a decompressor. PNG has universal cross-platform and browser support; BMP is Windows-native with limited macOS/Linux support.

Will the file size increase when converting PNG to BMP?

Yes, significantly. BMP stores uncompressed raw pixel data. A 1920×1080 24-bit BMP is approximately 6 MB regardless of content. The equivalent PNG is typically 1–3 MB due to DEFLATE compression. File size for BMP is determined by resolution and bit depth, not image content.

Is there a file size limit for PNG to BMP conversion?

The online converter supports input files up to 50 MB. For batch conversion of large PNG asset libraries to BMP — common in game modding and industrial workflows — use the desktop Total Image Converter (Windows) which handles files of any size and processes entire folders at once.

Convert PNG to BMP Online — Maximum Windows Compatibility From Any PNG

PNG is the modern lossless web format; BMP (Bitmap) is Microsoft's oldest raster format, built into Windows since 1985. Most modern software accepts PNG without issue, but certain Windows applications, legacy tools, game modding utilities, hardware interfaces, and embedded systems only accept BMP as input. Converting PNG to BMP produces an uncompressed pixel-for-pixel copy of the image in the BMP container — no data is lost, but the file size grows significantly because BMP stores every pixel as raw data with no compression. If the target application accepts both formats, PNG is almost always the better choice; if BMP is specifically required, this converter delivers it.

What Is a BMP File?

BMP (Bitmap Image File) is Microsoft's native raster image format, part of the Windows Device Independent Bitmap specification introduced with Windows 1.0 in 1985. BMP stores raw pixel data in a straightforward row-by-row structure, typically without compression.

Compression: Usually none — each pixel stored as raw RGB data. Optional RLE compression rarely used.
Color depth: 1, 4, 8, 16, 24, or 32 bits per pixel depending on variant.
Transparency: Supported in 32-bit BMP via an alpha channel, but rarely used in practice.
File size: Very large — a 1920×1080 24-bit BMP is ~6 MB uncompressed.
Compatibility: Every Windows application. Limited support on macOS and Linux.
Typical use: Windows system resources, legacy software input, hardware interfaces, embedded systems.

Who Needs PNG to BMP Conversion?

Game modders: Many PC games (older Bethesda, Valve, and strategy titles) use BMP format for texture files; modding tools require BMP input.
Industrial and embedded systems: CNC machines, PLC displays, embedded system HMIs, and industrial panels often accept only BMP for display images.
Legacy software users: Older Windows applications — from early versions of Paint to specialized engineering tools — require BMP input.
Windows wallpaper and system resources: Some Windows registry and customization utilities require BMP format for wallpaper or boot screen changes.
Developers targeting Windows GDI: Windows GDI (Graphics Device Interface) natively loads BMP; applications using GDI for rendering may require BMP input images.
Medical and scientific equipment: Imaging instruments that export or require BMP due to driver or firmware constraints.

PNG vs BMP — Key Differences

Property	PNG	BMP
Introduced	1996 (W3C standard)	1985 (Microsoft Windows)
Compression	DEFLATE lossless — 40–80% smaller than BMP	None (or optional RLE) — raw pixel storage
Transparency	Full alpha channel (0–255 per pixel)	32-bit only; rarely implemented
Typical file size (1080p)	1–5 MB	~6 MB uncompressed
Browser support	Universal	None natively
Platform support	All operating systems and apps	Windows-native; limited elsewhere
Best for	Web, sharing, any modern application	Legacy Windows apps, game modding, embedded systems

How PNG to BMP Conversion Works

The converter reads the PNG file and decompresses the DEFLATE-encoded pixel data to obtain the raw RGB (or RGBA) pixel grid. The decompressed pixels are then written into the BMP container format: a file header (size, type), a DIB header (image dimensions, bit depth, compression method), and the raw pixel data stored row by row, padded to 4-byte boundaries as required by the BMP specification. For 24-bit BMP output, any transparency in the PNG alpha channel is composited against a white background before storage, since standard 24-bit BMP has no transparency support. 32-bit BMP output can preserve the alpha channel. The resulting file is pixel-identical to the source PNG.

PNG to BMP Use Cases

Game modding texture replacement: Replacing game textures in titles that store assets as BMP; convert PNG source art to BMP before packing into the game's asset archive.
Industrial HMI display: Loading a logo or status graphic onto a factory display panel that only accepts BMP files via USB or serial transfer.
Windows boot screen: Creating custom Windows boot screens using tools that require BMP input in specific resolutions and color depths.
Legacy CAD and engineering tools: Inserting a PNG diagram into an older CAD application that only imports BMP for raster underlays.
Clipboard compatibility: Some Windows applications paste only BMP data from the clipboard; converting PNG to BMP first ensures the image pastes correctly.
Batch conversion: Convert a folder of PNG assets to BMP at once using Total Image Converter (Windows, $29.90) for game modding or industrial workflows.
