The free PDF to PDF/A converter prepares a document for long-term archiving. PDF/A is a version of the PDF format designed so a file stays readable far into the future, with fonts embedded and everything the document needs contained inside it. Upload your PDF, choose the PDF/A level, and download the converted file. It is free, adds no watermark, and needs no account.
An honest note on what this does. The tool converts your file toward the PDF/A standard using a well-established conversion process, embedding fonts and making the content self-contained. It does not run a formal compliance validation, so it prepares a file for archiving rather than issuing a certificate that guarantees it passes every PDF/A conformance check. For most archiving needs this conversion is exactly what is wanted; if you require certified, validated compliance for a regulated system, verify the output with a dedicated PDF/A validator.
How to Convert PDF to PDF/A
- Upload your PDF. Select the file or drag it onto the upload area.
- Choose the level. Pick the PDF/A level you need, such as 1b, 2b, or 3b.
- Convert and download. Save the archive-ready PDF/A file.
Preparing Documents for the Long Term
An ordinary PDF can become hard to open years later if it relies on fonts or resources that are no longer available. PDF/A solves this by embedding everything the document needs, so it looks and reads the same decades from now. This makes it the standard for archives, legal and government records, and any document that must be preserved reliably. The converter embeds fonts and self-contains the file to prepare it for that kind of long-term keeping, and lets you choose the PDF/A level that matches your requirement.
Is My File Safe?
Your files are handled securely. Uploaded PDFs are deleted from our servers immediately after processing, whether it succeeds or fails. The result is stored under a random, unguessable name and stays available to download for up to two hours, then it is automatically and permanently deleted. All uploads and downloads use a secure HTTPS connection.
When to Convert to PDF/A
- Archiving records. Prepare documents for long-term storage that stays readable.
- Meeting a standard. Convert files toward PDF/A where an archive or system expects it.
- Preserving important files. Keep contracts or records in a stable, self-contained format.
- Future-proofing. Embed fonts and resources so a file does not break over time.
