BMP to PDF Converter

Turn one or more BMP images into a single PDF, with one image per page. Arrange the page order and choose paper size, orientation, margins, and image quality before converting.

Supports BMP images only

Up to 10 BMP files, 20 MB each and 100 MB total. Each image's width and height must be no greater than 8,192 px; the sum of all images' width × height must not exceed 200 million pixels.

What your PDF will contain

BMP is a bitmap image format. This page places the images into a PDF document; it does not make their text editable.

One BMP

Creates a one-page PDF.

Several BMP files

Creates one PDF with one image per page, in the displayed order.

Image content

Images are encoded as JPEG inside the PDF. Transparent areas are filled with white.

Renaming .bmp to .pdf does not create a PDF. Use Image to PDF when you need to combine supported image formats other than BMP.

How to convert BMP images to PDF

1

Select your BMP images

Add up to 10 BMP files. Each file must be no larger than 20 MB, with width and height no greater than 8,192 px. Together, the files must stay within 100 MB and 200 million pixels, calculated by adding each image's width × height. All these limits apply together.

2

Check the page order

Review the list before converting. Use Move Up to adjust the order and remove any image you do not want in the PDF.

3

Choose the document settings

Select Auto, A4, Letter, or Legal, then adjust the available layout controls and the image-quality slider.

4

Convert and download

Select Convert to PDF to process the already uploaded images on the server. Download the completed PDF and check every page.

Plan a document with several bitmaps

Each selected file becomes a separate page; the tool does not place several pictures together on one page.

Consistent paper size

Choose A4, Letter, or Legal. For matching page orientation, select Portrait or Landscape instead of Auto.

Keep different image proportions

Use Auto page size. Different bitmap dimensions can produce different PDF page sizes.

Separate PDF files

Convert one BMP at a time; one submission produces one PDF.

For a multi-page document, compare the first and last images in the upload list before submitting.

Paper, margins, and image quality

Paper size controls the page layout. Image quality controls JPEG encoding inside the PDF; these settings solve different problems.

SettingEffectPractical check
Auto page sizeThe page follows the image dimensions. Orientation applies to fixed paper sizes.Auto does not mean original scanner DPI or a guaranteed physical print size.
A4, Letter, or LegalThe image is centered and scaled to fit, keeping its proportions.Choose the paper required by the recipient; the image is not cropped to fill it.
MarginsFixed paper sizes show options for 0, 5, 10, or 20 mm.The selected margin still applies after switching back to Auto, even though the control is hidden. To use Auto without margins, select None before switching.
Image qualityChoose a preset from “Strongest compression” to “Highest quality”; “High quality” is the default.Even “Highest quality” uses JPEG encoding. Check small text and thin lines at the intended viewing size.

Lower quality may reduce file size, but no setting guarantees an exact PDF size. Larger paper does not add detail to a low-resolution BMP.

Where conversion happens

Each selected batch uploads immediately. Preview and ordering changes reuse those uploaded URLs when the server generates the PDF.

Download the result when it is ready. Temporary files are handled by the service's cleanup process; this page does not promise a fixed deletion deadline.

BMP to PDF questions

For a file ending in .bmp, yes. Bitmap can also describe other raster images, so check the actual file type before choosing this page.

No. Text in the BMP remains part of the image. Use Image to Text if you need to extract it; that is a separate task.

No. The PDF contains JPEG-encoded versions of the images. Keep the original BMP files if you need their original bytes or unaltered image data.

A fixed paper size, margins, and the image's proportions determine how much space it occupies. Review those settings before converting again; changing page orientation does not rotate the picture itself.
