BMP to PDF - Free Online Browser Tool

Convert BMP bitmap graphics into pages of a PDF document in your browser.

A BMP holds every pixel uncompressed, which is why the files are enormous and why anything that has to be emailed wants a PDF instead. The browser decodes the bitmap and this writes it onto pages.

This bmp to pdf utility runs completely inside your web browser. Your document is opened locally and processed on your own device using JavaScript and WebAssembly, so your file is never uploaded to any server. There is no signup, no watermark and no limit on how many documents you can handle.

  • 100% client-side - files never leave your device
  • Instant processing, no upload wait
  • Works on desktop, tablet and mobile
  • Free forever, no account required

How to Use the BMP to PDF Tool

Four steps, and the whole thing runs locally on your own device.

  1. Add the bitmaps

    Choose one or more BMP files, and each one becomes its own page in the result.

  2. Pick the page size

    Use A4 for a printed document, or fit the page to the bitmap so its edges reach the edge of the paper.

  3. Decode and place

    The browser reads the Windows bitmap and the pixels are written onto a page as a high-quality JPEG.

  4. Download the PDF

    Save the document locally; nothing is uploaded while it is being built.

Frequently Asked Questions

Why put a BMP into a PDF at all?

A PDF opens on phones, email clients and print shops alike, and the JPEG encoding inside it usually makes the file far smaller than the uncompressed original.

Are the bitmap colours preserved?

The picture is re-encoded at high JPEG quality, which keeps the visual appearance but is not a mathematically lossless copy of every pixel.

Can scanned or technical bitmaps be converted?

Yes, provided the file is a Windows BMP the browser recognises; a variant it cannot read is refused with a message rather than half-converted.

Does an old palette-based bitmap work?

Yes. The browser decodes an indexed bitmap into full colour before the page is built, so an image from an old scanner still comes out correct.

Can several bitmaps become one document?

Yes, add them together and each file lands on its own sequential page, in the order you selected them.
