PDF/A for Archiving and Court Filing
Updated
Short answer: Drop the PDF into PDF to PDF/A to get a PDF/A-2 copy with every font embedded, then check it with a validator if the portal is strict.
Courts, government portals, universities and records departments often ask for PDF/A because an ordinary PDF can depend on things that won't exist in twenty years: fonts on the author's computer, external links, scripts. PDF/A is the ISO standard that rules those out.
Step by step
Step 1: Finish the document first. PDF/A is meant to be final, so make edits, fill forms and sign before converting.
Step 2: If the file has a password, remove it; PDF/A doesn't allow encryption.

Step 5: If the portal checks compliance strictly, run the file through a free validator such as veraPDF before submitting.
Why this works, and what to watch for
PDF/A (ISO 19005) is a restricted form of PDF designed so that a file displays identically in any reader, indefinitely. Every font must be embedded, colours must be defined against a known colour profile, and anything that depends on the outside world or on runtime behaviour, such as JavaScript, external content, encryption, audio and video, is forbidden. The file also carries metadata declaring which part of the standard it follows.
PDF to PDF/A produces PDF/A-2, the version most portals accept, using Ghostscript. Fonts are embedded, colours are converted to RGB with an sRGB output intent, and anything the standard forbids is left out. The pages should look unchanged. Interactive extras are what can disappear: scripted form behaviour, embedded media and links to external content.
The versions cause confusion. PDF/A-1, based on PDF 1.4, is the oldest and strictest and allows no transparency. PDF/A-2 adds transparency, JPEG 2000 and better compression, and is what most systems mean today. PDF/A-3 additionally allows any file to be attached, which is used for e-invoices. If a portal names PDF/A-1b specifically, check its documentation, as a few older systems still require it.
Conversion is not certification. Most portals open the file, look for the PDF/A identifier and accept it; strict archive systems run a full validator. If yours is strict, veraPDF is the reference open-source validator and will tell you exactly which rule a file breaks. Scans with unusual colour spaces and files with damaged fonts are the usual troublemakers, and running Repair PDF first can help with the latter.
Court rules vary. Many e-filing systems simply require text-searchable PDFs under a size limit, so OCR scanned exhibits and compress them if needed, and check the specific court's rules before filing.
