Why convert P7M to BMP?
A P7M file is a digitally signed envelope in the PKCS#7 format, widely used for signed PDFs, e-invoices and certified email. The image shows the content inside the signature envelope: the pages of a signed PDF, a signed email with its headers and body, or the full text of any other signed document.
BMP stores every pixel uncompressed, so the image is exact and simple to read by any software that handles Windows bitmaps.
Frequently Asked Questions
How do I convert P7M to BMP?
Drop your P7M file above and press Convert. Our servers open the signature envelope, extract the signed content and render it as pages. The result is saved as an uncompressed BMP bitmap, ready to download.
What appears in the BMP when a P7M file wraps a signed PDF?
The PDF inside the signature envelope is extracted and its own pages are rendered, so the BMP shows the original document.
How does a P7M holding a signed email or XML invoice look as BMP?
A signed email is laid out with its From, To, Subject and Date headers and body. Other text content, such as an XML e-invoice, is shown in full under a “Signed document” heading.
What happens when a P7M file fills several BMP pages?
Each page is rendered at 144 dpi and saved as its own BMP image, named page-1, page-2 and so on, and they download together as one ZIP. A single page downloads as one BMP file.
What kind of BMP does the P7M converter create?
A standard Windows bitmap with every pixel stored uncompressed, so the image is an exact copy of the rendered result.
Is my .p7m file kept private?
Your file is uploaded over an encrypted connection, converted on our servers and deleted automatically within 24 hours. We never read, share or keep your files, and no account is needed.
