About Bitmap Image
Uncompressed raster format by Microsoft.
About Portable Document Format
Predictable layout on every device, strong print fidelity, universal viewers, and support for signatures and forms. Editing is harder than editing a word processor document; reflow, accessibility, and text extraction depend on how the PDF was produced.
Format referenceWhy convert BMP to PDF?
- The output can be optimized for a different balance of file size, transparency, and visual fidelity.
- PDF may be the better handoff format for a design tool or publishing workflow.
- The converted copy can be tested in the destination app before the source archive is changed.
- Converting BMP to PDF can make a photo or graphic work in software that does not accept the source format.
Will quality change?
The result is a new document, not a byte-for-byte copy. Keep the source for reference and print checks. Check a sample before processing a large batch.
