Free PDF/A validator from Solid PDF Tools
The process is fairly straightforward — you set some simple parameters to allow password protected PDF files to be opened, and whether you wish you compress the results file. You’re then run through the process of sending the files you wish to validate to their server — and a few minutes later, the results are sent back to you via email.
They describe the process as follows:
Validating PDF/A is as easy as sending an e-mail.
This simple-to-use free online service is a quick solution for validating PDF files for PDF/A-1b (ISO 19005-1) compliance.
I completed the process myself with a test PDF file — and it produced fairly detail results. My only complaint was that the process fired up my default client-based email program to send my PDF to their server. Since I use a corporate version of Gmail, this meant that Microsoft Outlook was opened in error. I had to close down Outlook, and cut and paste the email body across to Corporate Gmail. Of course, one always has to be greatful for a free service, however, I found the conversion process included just a little too much advertising.
Definitely worth taking a look though…
