PDF to BMP Converter
Convert every page of a PDF into a BMP image. Upload a PDF, choose a resolution, and download each page as an uncompressed bitmap file.

Pro Tips
- •BMP files are uncompressed, so they're significantly larger than PNG or JPG for the same page - expect bigger downloads
- •Each pixel is stored at full 24-bit color depth with no compression, guaranteeing pixel-perfect accuracy
- •Higher resolution multipliers produce sharper images but much larger file sizes with this uncompressed format
- •The whole file is rendered locally in your browser - nothing is uploaded anywhere
Most Popular
Most users convert at 1x or 2x resolution to keep the uncompressed file size manageable
When to Use This Tool
Convert PDF pages to BMP for older software or embedded systems that only support the basic bitmap format.
Generate BMP images for Windows desktop applications, icons, or wallpapers that expect the native bitmap format.
Store PDF pages in an uncompressed format to guarantee no compression artifacts are ever introduced, at the cost of larger files.
Export PDF pages as BMP for processing pipelines or tools that specifically require uncompressed bitmap input.
How It Works
Read the uploaded PDF file as binary data directly in your browser
Parse the file into a PDF document using the PDF.js library
For each page, render its full content onto an HTML canvas at the selected resolution
Read the canvas's raw pixel data and manually encode it into the BMP file format, including the file header and bitmap info header
Package the encoded bytes as a downloadable BMP file for each page
100% Private
Files never leave your device. All processing happens locally in your browser.
Lightning Fast
Powered by PDF.js + custom BMP encoder for optimal performance on modern browsers.
Secure
No data collection, no tracking, no sign-up required.
Frequently Asked Questions
Why are BMP files so much larger than PNG or JPG?
BMP stores every pixel's color value directly with no compression, unlike PNG (lossless compression) or JPG (lossy compression). This guarantees pixel-perfect output but results in significantly larger files.
What bit depth does the output use?
Pages are exported as 24-bit BMP files (8 bits each for red, green, and blue), which is the most widely compatible BMP format across different software.
Is my PDF uploaded to a server?
No. The entire file is read, rendered, and encoded locally in your browser. Your document never leaves your device.
Can I open BMP files in image editors?
Yes. BMP is supported natively by virtually every image editor and operating system, including Windows Paint, Photoshop, and GIMP.
Does BMP support transparency?
This tool exports 24-bit BMP without an alpha channel, so any transparency in the original PDF is filled with white before conversion.
