Frequently Asked Questions

Why are BMP files so large, and will the PDF be smaller?
BMP files store raw uncompressed pixel scanlines. When converting to PDF, topdf.click compresses the bitmap streams, typically producing a significantly smaller PDF file.
Can I combine multiple BMP files into one multi-page PDF?
Yes. You can upload multiple BMP images simultaneously, arrange them in order, and compile them into a single multi-page PDF.
Does BMP to PDF work on macOS and Linux?
Yes. Because the converter runs entirely in your web browser, it works seamlessly across Windows, macOS, Linux, iOS, and Android.
