Browse document file types and extensions for reading, editing and sharing, including fixed-layout pages, ebooks, office files and specialist documents.
Choose a workflow
Distinguish reading a finished document from editing its source. Decide what the recipient needs to do before choosing an application. The workflow checklist is available while format-specific records await review.
Choose reading or editing
A reviewed viewer and a reviewed editor are different pieces of evidence. Check both sections of an individual guide.
Preserve a source copy
Modify a copy and check the output in the recipient's application before replacing an original.
Do not enable active content
Do not enable scripts or macros merely because a filename looks familiar. Format recognition is not a malware scan.
Common tasks and format choices
Typical workflows
Read fixed-layout pages, preview Markdown, open saved email, edit office documents, or read ebooks. The correct app depends on what the recipient needs to do.
Compatibility checklist
PDF and XPS favor fixed presentation; ODT is intended for editable documents; EPUB adapts to reading software. Verify fonts, layout, and active content in the receiving app.
