BMP to PDF
Turn BMP images, such as old Windows screenshots and scans, into one PDF. BMP files are huge; in the PDF they are stored compressed, so the result is usually far smaller. Drag them into order, choose the page size and margins, and download.

About BMP files
BMP is an old, uncompressed Windows image format. A single screenshot can be several megabytes. Converting to PDF compresses the pictures without losing detail and gives you one file that opens everywhere.
Each BMP becomes a page; transparent areas stay transparent.
Tip: Is the PDF too big to email? Run it through Compress PDF.

Frequently asked questions
Will my BMP images lose quality?
No. Images are stored without loss in the PDF.
Can I combine several files into one PDF?
Yes. Every file becomes a page in one PDF, in the order you set.
What page size should I pick?
A4 or Letter for printing; "Same size as the image" to keep the image's own shape.
Is it free?
Yes. There is no sign-up, no limit on files and no watermark.
Are my files uploaded?
No. The tool runs inside your web browser and works on the file on your own device. Nothing is sent to a server, so private documents stay private.
