What PDF to BMP does
PDF to BMP renders each page onto a white canvas and encodes the pixel data in a 32-bit BMP file. Single-page sources download directly, while multi-page documents produce one numbered BMP per page in a ZIP.
BMP is simple and broadly readable in desktop imaging software, but it is usually much larger than PNG or JPEG. DPI directly controls the pixel dimensions and therefore has a large effect on output size.
How to use PDF to BMP
- Select one verified PDF up to 25 MB.
- Choose a render DPI from 72 through 300.
- Convert the pages, download the BMP or ZIP, and confirm that the large output suits the destination.
Important details
BMP prioritizes simple pixel storage
The encoder writes a 32-bit bitmap from the rendered page. It does not apply JPEG-style quality controls, so dimensions rather than a quality slider are the main size lever.
Large pages create very large files
A 32-bit image uses roughly four bytes per pixel before file overhead. Raising DPI can quickly multiply both memory use and download size, even for visually simple pages.
Practical uses
- Supply page rasters to legacy desktop software that expects BMP.
- Create uncompressed-style working images for a controlled local workflow.
- Export a short PDF into numbered bitmap pages for compatibility testing.
Privacy and limitations
The PDF is rendered and BMP files are encoded in the browser. The document is not sent to PagesTools.
The source is capped at 25 MB and 100 pages with 72–300 DPI and strict canvas limits. BMP outputs can be extremely large, multiple pages are separate files in ZIP, and text, vectors, transparency, links, and forms are flattened into pixels.
