Image to BMP Converter & Bitmap Maker

Need to make a BMP file from a normal image? This free online bitmap maker converts JPG, PNG, WebP, and AVIF into an uncompressed BMP in a single step. Every pixel is written into a plain raster grid for legacy Windows apps, point-of-sale systems, and software that only accepts bitmap files — no account or watermark required.

A Simple Online Bitmap Maker for BMP Files

A bitmap (BMP) file stores the color of every pixel in a plain raster grid, with no compression. This online bitmap maker turns a regular image into that raw format in one step: upload a JPG, PNG, WebP, AVIF, TIFF, GIF, or ICO file and the tool writes out a standard .bmp you can download. There is no format dropdown to manage — this route is locked to BMP output, so the converter is ready the moment your image is uploaded.

Because standard BMP has no reliable alpha channel, any transparency from a PNG is flattened onto a solid white background so the picture renders correctly in older software. The trade-off for that simplicity is size: a BMP holds full pixel data, so the file is far larger than the JPG or PNG you started with. That is exactly why people still make BMP files — for tools and devices that expect raw, uncompressed input rather than a modern compressed web format.

Heads up: BMP output is much larger than JPG, PNG, or WebP because bitmap files are not compressed.

Source Formats You Can Turn Into BMP

JPG / JPEGConvert a JPG to BMP online when a legacy app rejects compressed photos.
PNGPNG to BMP flattens transparency to white and writes raw pixels.
WebP & AVIFConvert modern WebP or AVIF files back into a classic BMP for older programs.
TIFF, GIF & ICOOther common raster inputs are accepted and saved as a single BMP file.

BMP Compared With Common Image Formats

Bitmap files solve a narrow but real compatibility problem — pick the format that matches your destination.

Format	Best For	File Size	Transparency
BMP	Legacy Windows apps and raw raster workflows	Very large	Limited or unreliable
PNG	Lossless graphics and transparency	Medium to large	Yes
JPG	Photos and small upload files	Small	No

Choose BMP only when a tool, device, or workflow specifically asks for bitmap output.

Practical Use Cases

Real-world workflows where this tool shines.

Engineers

Prepare image assets for embedded GUI systems that only parse raw bitmap files.

Technicians

Create compatibility files for older print, label, point-of-sale, or machine-interface software.

QA Teams

Generate raw BMP inputs when testing software that only accepts bitmap files.

Who This Is For

The people and teams this tool is especially useful for.

Archivists

Store images in an absolute, raw pixel format free from proprietary compression.

Windows Users

Make bitmap files for older desktop apps, themes, launchers, and internal tools.

Print Operators

Convert incoming images into the BMP format required by specialized devices.

How to Make a BMP File From Any Image

Upload one image and the bitmap maker creates an uncompressed BMP you can download — ideal for legacy Windows, point-of-sale, and specialized software workflows.

Upload your image

Drag and drop your JPG, PNG, WebP, or AVIF onto the upload zone, or click to browse from your device.

BMP output is locked in

This image to bitmap route automatically uses BMP as the destination, so there is no format to choose.

Click Convert to BMP

Start the conversion and watch the progress while the tool maps every pixel into an uncompressed grid.

Download your BMP file

Save the finished bitmap to your device and drop it into legacy Windows apps, POS systems, or print software.

Why Use This BMP Maker & Bitmap Converter?

Reach for BMP when exact raster output and legacy compatibility matter more than a small file size.

Make a BMP in One Click

Upload an image, convert, and download — a straightforward bitmap maker with no settings to configure.

Pure, Uncompressed Pixels

No JPEG-style artifacts are added. The output is exactly what specialized printing hardware expects.

Legacy & Embedded Support

Built for older Windows software, point-of-sale terminals, and embedded systems that only read bitmaps.

Automatic Transparency Flattening

Transparent PNG areas are replaced with a clean white background so the image renders correctly.

Free, Private, No Account

Convert as many images to BMP as you need — no watermark, no sign-up, and nothing to install.

Frequently Asked Questions

Common questions about making BMP files, bitmap vs BMP, uncompressed output, file size, and flattening transparency.

Upload your JPG, PNG, WebP, or AVIF, wait a moment while the tool processes it, then download the BMP. The output format is fixed to BMP on this page, so there is nothing else to set.

The fastest way to create a BMP file online is to convert an existing image. Upload any supported picture and the bitmap maker writes out a standard .bmp file you can save to your device.

Bitmap is the general idea of storing an image as a grid of pixels. BMP is a specific bitmap file format, historically tied to Windows, that saves those pixels with little or no compression.

Bitmaps are mostly used in specialized fields: legacy medical imaging software, embedded and point-of-sale systems, and certain industrial printing machines that require raw pixel data instead of compressed web formats.

BMP does not compress image data — the color of every pixel is written out in full. That guarantees a raw, predictable file but makes BMP much larger than a comparable JPG or PNG.

Standard BMP files do not reliably support transparency. This tool automatically flattens any transparent areas, such as those from a PNG, onto a solid white background.

Yes. The tool reads modern formats like WebP and AVIF and writes them back into a classic, uncompressed BMP so unsupported or legacy programs can open the image.

Converting to BMP avoids adding new JPEG-style compression, but it cannot recover detail. If the source was already a compressed JPG, the BMP keeps that existing quality — it does not restore lost pixels.

Usually no. BMP files are far too large for web delivery. Use BMP for legacy or technical compatibility, and stick with JPG, PNG, WebP, or AVIF for websites.
