We had hundreds of BMP scans from an old document scanner and needed them as PDF for our archive. Batch conversion worked perfectly and saved hours of manual work.

Old Windows Paint files in BMP format needed to be submitted to a portal as PDFs. The output quality was clean and the portal accepted every file.

Needed to prepare a batch of BMP technical drawings as a single PDF document package. The tool combined multiple BMPs into one PDF exactly as needed.

BMP to PDF Converter — Frequently Asked Questions ▼

What is a BMP file?

BMP (Windows Bitmap) is the uncompressed raster format Microsoft introduced with Windows 3.0 in 1990. Each pixel is stored individually, so even a screenshot can run to several megabytes.

How do I convert BMP to PDF online?

Upload your .bmp file above. The converter reads the bitmap, embeds it on a PDF page sized to fit, and returns a PDF you can download, email, or print.

What page size does the PDF use?

By default the page is sized to fit the bitmap at 96 DPI. For fixed paper sizes (A4, Letter) or precise DPI control, use Total Image Converter on the desktop.

Can I combine several BMP files into a single PDF?

Online conversion handles one file at a time. To merge multiple bitmaps into a multi-page PDF, use Total Image Converter on Windows, which has a built-in combine-to-PDF mode.

Will the PDF be smaller than the BMP?

Usually yes. The converter applies Flate or JPEG compression inside the PDF, which can shrink the file dramatically compared with the raw BMP.

What is the maximum file size?

The online converter accepts BMP files up to 50 MB. That covers nearly all screenshots and scans. For larger bitmaps, use the desktop version.

Are my uploaded files kept private?

Uploaded files are deleted automatically after you download the PDF. Nothing is stored or shared. For confidential bitmaps, run conversion locally with Total Image Converter.

Convert BMP to PDF — Wrap Windows Bitmaps in a Portable Document

BMP files are heavy, Windows-specific, and clumsy to email or print. Converting BMP to PDF wraps your bitmap in a paginated document that opens on any device, prints cleanly, and embeds neatly into reports. Drop your .bmp file above.

What Is BMP?

BMP (Windows Bitmap) is the raster format Microsoft introduced in 1990 for Windows 3.0. BMP stores pixels uncompressed, supports 1 to 32-bit colour depth, and is the default capture format for many legacy screen-grab and CAD tools. The lack of compression makes BMP impractical for sharing.

What Is PDF?

PDF (Portable Document Format) is Adobe's universal page-faithful document format, standardised as ISO 32000. Every operating system, browser, smartphone, and printer driver renders PDF natively. PDF preserves the embedded image exactly and adds metadata, security, and print-ready pagination.

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.
