PDF/A-2b keeps how the pages look by storing them as images of up to 144 dpi, 4 megapixels per page at most. Text is no longer searchable; forms, attachments, links and signatures don't carry over. If you're submitting it somewhere, check their requirements too.
You can pick several PDFs. Each gets its own result, and you can also download them all as one ZIP.

PDF/A is the version of PDF meant for long-term archiving: everything needed to display the file is stored inside it. This tool creates a PDF/A-2b copy from images of the pages, with an embedded sRGB colour profile. The look is kept, but text isn't searchable and forms, links and attachments are dropped. Check which version the recipient expects.

How it works
Pages are stored as images of up to 144 dpi. That's enough to read on screen and print on A4. Even so, zoom in on small tables full of figures before you submit anything.
Choose the PDF and press “Save PDF/A”.
Worked example
An online application asks for attachments in PDF/A, and you have a five-page scan. Make a PDF/A-2b copy, then reread the instructions: do they say “PDF/A-2b”, or just “PDF/A”? If they ask for PDF/A-1a or searchable text, this file won't be accepted.
Questions people ask
What does the “b” in PDF/A-2b mean?
Level b guarantees the document looks the same everywhere. Level a also requires a tagged text structure, which an image-based copy doesn't have.
Can I search the text in the PDF/A copy?
No, the pages are images. Keep the original with its text separately.
Can I add a password to a PDF/A file?
PDF/A doesn't allow encryption. If you protect the file afterwards, it's no longer a valid archive format.
