Why convert P7M to ICO?
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.
ICO output is a 256 × 256 pixel Windows icon: the image is scaled to fit with its proportions kept, and the surrounding space is transparent.
Frequently Asked Questions
How do I convert P7M to ICO?
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 a 256 × 256 ICO icon, ready to download.
What appears in the ICO when a P7M file wraps a signed PDF?
The PDF inside the signature envelope is extracted and its own pages are rendered, so the ICO shows the original document.
How does a P7M holding a signed email or XML invoice look as ICO?
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.
Which part of the P7M becomes the ICO icon?
The first page of the rendered content is used for the icon, fitted inside the 256 × 256 square with its proportions kept.
What size is the ICO made from a P7M file?
The icon is 256 × 256 pixels, the largest standard Windows icon size. The image is fitted inside the square with its proportions kept and a transparent surround, stored as a PNG-compressed icon.
