BMP vs PDF
BMP — Bitmap image. BMP is an uncompressed Windows image format. Files are very large because every pixel is stored as-is, so it is rarely used outside older Windows software.
PDF — Portable Document Format. PDF keeps a document looking the same on every device, with fixed pages, fonts and layout. That makes it ideal for sharing and printing, but hard to edit.
Convert BMP to PDF when you need a file for sharing, printing and archiving documents. BMP is better suited to legacy Windows programs.
FAQ
5Are my files uploaded anywhere?
No. The conversion runs in your browser using your own device’s processor. Your files are never sent to a server, so nobody — including us — can see them. You can even disconnect from the internet after the page loads.
Will I lose quality?
Each BMP image becomes one page, sized to the image. The image is converted to high-quality JPG inside the PDF.
Is there a file size or daily limit?
No limits, and no sign-up. Because nothing is uploaded, we don’t pay for your conversions and have no reason to cap them. Very large files are limited only by your device’s memory.
Can I convert many BMP files at once?
Yes. Add as many files as you like; each is converted to PDF and combined into a single PDF, one page per image.
Does it work on iPhone and Android?
Yes. It works in any modern browser — Safari, Chrome, Firefox or Edge — on phones, tablets and computers. Older or low-memory phones may be slower with very large files.
