Prepare PDF/A Structure
Convert a PDF toward PDF/A-1b, the ISO standard for long-term archiving, processed in your browser.
Drag a PDF here, or choose a file
Adds the archival structure PDF/A-1b requires.
You can also paste a file directly (Ctrl+V or ⌘V).
This tool runs entirely in your browser. Your file is not uploaded to a server at any point.
What PDF/A Actually Requires
PDF/A is an ISO standard built for one goal: a file that still opens correctly decades from now, independent of whatever software or fonts happen to be installed at the time. That means a self-contained color profile instead of relying on a viewer's default, metadata that identifies the file as PDF/A, and - critically - every font embedded directly in the file rather than referenced by name.
Adds the Structure, Can't Fix Every File Completely
Filevolo adds the color profile and metadata PDF/A requires. What it can't always fix automatically is a font that was never embedded in the first place - there's no way to reconstruct a font file that was never included, only to flag it. If your PDF used standard fonts (Helvetica, Times, Arial) without embedding them, you'll get an honest warning after conversion rather than a file that quietly falls short. Use Check PDF/A afterward for preliminary checks, then use a full validator for the required profile.
