Why convert BMP to PDF?
PDF makes large BMP bitmap images easier to print, submit as documents, email as one attachment, or share across devices.
Use a page matching each bitmap or choose A4 or Letter with your preferred orientation and margins. Several BMP images can become one ordered PDF or separate documents.
Frequently Asked Questions
Can I combine multiple BMP images into one PDF?
Yes. Add the BMP images in the order you want them to appear and choose One PDF. Each bitmap becomes one page. Choose Separate PDFs when you want individual documents in a ZIP.
Why convert BMP to PDF?
PDF is easier to print, submit as a document, email as one attachment, and open across devices. It also lets you arrange several BMP images as pages in one document.
Which PDF page size should I choose?
Choose Fit image for a page that follows the bitmap's dimensions. Choose A4 or Letter for printing and document systems that expect a standard paper size.
Can I choose portrait or landscape pages?
Yes. A4 and Letter pages can use automatic, portrait, or landscape orientation. Automatic follows the shape of each BMP image.
Can I add margins around each BMP image?
Yes. Choose no margin, a small margin, or a large margin. Each bitmap is centred and fitted to the page without changing its proportions.
What does Enlarge smaller images do?
On A4 or Letter pages, this lets a smaller bitmap fill more of the available page. Leave it off to avoid enlarging an image beyond its original pixel dimensions.
Does converting BMP to PDF reduce image quality?
The BMP is converted to a lossless image layer inside the PDF. Its visible pixels are retained, while the selected page layout controls its printed size and position.
Does the PDF keep BMP metadata?
The PDF keeps the visible bitmap but does not copy BMP colour-profile metadata or other file details. Keep the original BMP when you need that information.
Are my BMP images uploaded?
No. BMP to PDF conversion runs locally in your browser. Your images are not uploaded to Crest Convert or stored on our servers.
How can I turn PDF pages back into BMP images?
Use the PDF to BMP converter to turn PDF pages into individual bitmap images.
