Convert BMP to PDF Online - Free, Private, No Upload

This tool converts BMP image files to PDF entirely in your browser. No file is uploaded to any server. Select one or more .bmp files, choose a page size and orientation, and the tool assembles each image into a separate page of a new PDF document. The result is available for download immediately.

What Is a BMP File?

BMP (Bitmap) is a raster image format developed by Microsoft. It stores pixel data without lossy compression, which preserves image quality but produces large file sizes. BMP files are natively supported by Windows applications and some legacy software, but the format has no support for multiple pages, text layers, or embedded metadata. PDF solves all of these limitations and is the standard format for document exchange across all operating systems and devices.

Page Size and Orientation Options

Each BMP file becomes one page in the output PDF. You can choose from four page size presets:

Portrait and landscape orientation are both supported. When a fixed page size is selected, the image is scaled to fit the page and centered. When Auto is selected, the page matches the image exactly with no scaling.

How to Convert BMP to PDF

  1. Upload your BMP files - drag and drop or click to browse. Multiple files are supported.
  2. Choose page size and orientation - select A4, Letter, Legal, or Auto, and portrait or landscape.
  3. Click Convert to PDF - the tool assembles all images into a single PDF, one page per image.
  4. Download your PDF - the file is ready immediately in your browser.

After converting, you can use our PDF compressor to reduce the file size, or our merge tool to combine it with other documents. You can also add password protection to the resulting PDF.

FAQ

Upload your .bmp file to this tool, select a page size and orientation, then click Convert to PDF. Each BMP file becomes one page in the output PDF. The conversion runs in your browser and the file is ready to download immediately, with no server upload required.

No. BMP is a raster image format that stores pixel data for a single image with no compression, no text layer, and no multi-page support. PDF is a document format that can contain images, text, vector graphics, and multiple pages. PDF is the standard for document exchange and is supported by every major operating system, browser, and device.

No. The conversion runs entirely in your browser. Your BMP files never leave your device. Once you close the page, no trace of your files remains anywhere.

Yes. Upload multiple BMP files and the tool combines them into a single PDF with one page per image. You can reorder the images before converting by dragging them in the file list.

Four options are available: A4 (595 x 842 points), Letter (612 x 792 points), Legal (612 x 1008 points), and Auto. Auto sizes each page to match the exact pixel dimensions of the BMP file, with no scaling applied. The fixed sizes scale the image to fit the page and center it.

BMP files can be opened by Microsoft Paint, Windows Photos, Adobe Photoshop, GIMP, and macOS Preview. Most modern browsers also display .bmp files directly. However, BMP is not universally supported across all platforms and email clients, which is one reason to convert to a more portable format like PDF.

BMP is still used in some Windows applications, legacy printing workflows, and certain industrial systems. For general use it has largely been replaced by PNG (lossless, smaller file size) and JPEG (lossy, much smaller). If you receive a .bmp file and need to share or archive it, converting it to PDF gives you a format that is universally readable and compact.

BMP stores raw pixel data with no lossy compression. A 1920 x 1080 24-bit BMP file is approximately 6 MB regardless of content. PDF wraps the image in a document structure, and the output file size depends on the image dimensions and the page size chosen. For large BMP files, using the Auto page size option preserves the original dimensions without scaling.

Yes. Windows saves screenshots in BMP format by default in some legacy workflows. Upload the .bmp screenshot and use Auto page size to preserve the original screen dimensions exactly, or choose A4 or Letter to fit it into a standard document page.

Both BMP and PNG are lossless raster formats that preserve pixel data without quality loss. The key difference is compression: PNG uses lossless deflate compression to reduce file size significantly, while BMP stores raw uncompressed pixel data. A PNG of the same image is typically 3 to 10 times smaller than a BMP. Both can be converted to PDF using this tool or our PNG to PDF converter.
