About BMP output
BMP is still required by some older software, industrial printers and embedded displays. Because it is uncompressed, BMP files are large: an A4 page at 150 DPI is about 6 MB.
For everyday use, PNG gives the same exact pixels in a much smaller file.
Tip: Need ordinary images? PDF to JPG and PDF to PNG make smaller files.

Frequently asked questions
Why are BMP files so big?
BMP stores every pixel without compression. Use PNG for exact pixels in a smaller file.
Can I convert only some pages?
Yes. Type them in the Pages box, or click pages to leave them out.
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.
