About this BMP to PDF
Combine multiple images into a single PDF document with our bmp to pdf tool. Drop your BMP (bitmap) files, arrange them as needed, and convert them into a single PDF. By default, one image is placed per page; you can also place 2 or 4 images per page.
Choose Fit to image, A4, Letter, A3, A5, or Legal, then adjust orientation, fit mode, margins, images per page, background, border, and optional PDF title. BMP is decoded and embedded as JPEG at 92% quality, so file size and sharpness may change.
Your privacy is the default. Your selected files are processed in your browser and are not uploaded to our server; all processing happens client-side using browser-side libraries such as pdf-lib, browser canvas/image decoding, HEIC conversion, and UTIF.js for TIFF where needed. Closing the tab clears the working session from this page; downloaded files remain on your device.
This tool is free to use with no signup required. Large files may be limited by your browser’s memory and device performance. Part of PDF Tools Base, a privacy-first collection of 161 PDF utilities. Bookmark the page for next time, and explore related tools in the footer below.
Frequently asked questions
Is BMP to PDF safe to use?
Yes. Everything happens in your browser. Your selected files are processed in your browser and are not uploaded to our server. Closing the tab clears the working session from this page; downloaded outputs remain on your device until you delete them.
Do I need to register or sign in?
No. No account, no email, no sign-up. Open the page and start using the tool immediately. Free to use, no signup needed.
Is there a watermark on the output?
No. PDF Tools Base never adds a watermark or branding to your output. Your final file is clean — just what you produced from the original.
Is there a file size limit?
There is no fixed limit. Images are processed in your browser, so RAM, image dimensions, file count, format conversion, and device performance affect what is feasible. Phones may struggle with very large photos or many pages; try fewer images, smaller images, or a desktop browser.
Does this work on mobile devices?
Yes. The tool works on all modern mobile browsers: Chrome on Android, Safari on iOS, Firefox, Edge, Brave. The drag-and-drop also accepts files from your phone’s file manager.
What image formats does bmp to pdf support?
Accepts BMP files only (converted to JPEG at 92% quality before embedding). Drop multiple at once and order them as needed.
How is image quality handled?
BMP is browser-decoded and embedded as JPEG at 92% quality, so sharpness and file size may change.
