How to pdf vs pdf/a explained

  1. 1. Read which PDF/A part the recipient asked for.
  2. 2. Convert and validate with a tool that reports failures.
  3. 3. Do not rename an ordinary PDF and call it archival.

An ordinary PDF is a flexible container. It may rely on fonts that are not embedded, on transparency, on JavaScript, or on encryption. PDF/A is a profile for long-term storage: the file should carry what it needs to look the same later, and it should avoid features that depend on a particular viewer’s extras. There are several PDF/A parts and conformance levels. A file is not PDF/A because someone renamed it or because a website added a badge.

Validation is a real check against those rules. This app does not run that check, so it will not write a PDF/A claim. If a records office requires a level, use a validator and a converter you can run locally, and keep their report. The work this guide points to stays in the browser. No upload is required to follow it.

PDF vs PDF/A explained stays on this device. The download is the copy you keep, and Weesize does not store a second one. Close the tab when you are finished and the bytes are gone.
