Fonts and resources are embedded so the file never depends on the viewer’s system.
No watermark
The archived PDF is clean, with nothing stamped onto it.

Phone, tablet, or computer — it runs in the browser you already have.
What does converting to PDF/A do?
PDF/A is a special, standardised version of PDF designed so a document will still open and look exactly the same many years from now. It does this by making the file self-contained: fonts are embedded, external dependencies are removed, and features that could break over time are avoided. A normal PDF might rely on a font installed on your computer today; a PDF/A carries everything it needs inside it. Because this tool runs entirely in your browser, the conversion happens on your own device and the file is never uploaded.
When should you convert to PDF/A?
Convert to PDF/A when a document needs to be preserved or submitted to a system that requires the archival standard. Courts, government portals, libraries, and universities often mandate PDF/A for filings, records, and theses precisely because it guarantees the file will remain readable in the long term. Businesses use it to archive contracts and compliance records. If you are storing something important for years, or an official system asks specifically for PDF/A, this is the format to produce.
How to get the best results
Finish all your edits before converting, since PDF/A is meant to be a final, archival copy rather than a working draft. Make sure the document already contains the fonts and content you want, because the conversion embeds what is there. If the file is a scan, consider running OCR first so the archived version is searchable as well as preserved. Keep both your original PDF and the PDF/A: the archival copy is for long-term storage, while the original stays your editable source.
Limitations to be aware of
PDF/A deliberately restricts features that threaten long-term readability, so some interactive elements — certain scripts, external links, or transparency effects — may be simplified or removed to meet the standard. That is by design: the goal is durability, not interactivity. There are also different PDF/A conformance levels for different needs; most archiving cases are well served by a standard level. If a system requires one specific level, check which before submitting, and always keep your editable original.
Common mistakes and how to avoid them
The most common mistake is treating a PDF/A as an editable working file; it is an archival copy, so keep your original PDF for future changes. Another is converting a scan without OCR, leaving an archived image with no searchable text — run OCR first if searchability matters. People also sometimes forget that a specific portal may require a particular PDF/A level; confirm the requirement before submitting. Finally, verify the important content looks right after conversion.
Using it on mobile and desktop
On a computer, convert a finished contract or thesis to PDF/A before filing it in a long-term archive or submitting it to an official system. On a phone, produce a PDF/A of an important document on the spot; everything runs locally, so nothing is uploaded. Because there is no app to install, the same link works on every device, and the archival file opens the same everywhere.
Why convert here instead of another site?
The documents most often archived as PDF/A — legal filings, records, official submissions — are exactly the ones that should not be uploaded to a stranger’s server, yet most online converters do just that. This tool never uploads your file; the conversion happens inside your browser, so a sensitive record stays on your device. There are no watermarks, no account, and no limit on how many files you convert. For archival documents, keeping the process local is the sound choice.
