No. All PDF parsing, format validation, archiving standard restructuring, and document packaging export logic runs entirely offline in your local browser.
Up to 200MB per file. 1. PDF/A-1 (Legacy, best compatibility): For older archive systems, no embedded attachments, text and images only. 2. PDF/A-2 (Recommended): Best balance of compatibility and stability, supports high-res vector graphics and layers. 3. PDF/A-3 (Supports attachments): For archiving PDFs with embedded Excel, Word, or original source files.
The conversion performs archiving standardization: all fonts are embedded, image color spaces are standardized, dynamic scripts/multimedia/expired links are removed, editing is locked, and a long-term archive-compatible structure is generated.
No. Your local original PDF is never modified. All archiving operations are processed in browser memory only. A new PDF/A-compliant file is exported.
No export limits. The output PDF/A contains no additional watermarks. No registration required. Free for personal and commercial use.
PDF/A is a read-only archive standard. The converted file locks editing, annotation, and modification, supporting only viewing and printing. To modify, keep the original PDF for editing and re-archive.
How It Works
This PDF to PDF/A tool is built on the OpenDataLoader open-source local PDF parsing engine. All file processing is performed offline in your browser.
1. 1. Local PDF Complete Parsing: Reads all page layers, text, images, fonts, multimedia, scripts, and attachment data from the uploaded PDF into browser local memory.
2. 2. PDF/A Standards Validation & Cleaning: Performs standardized cleaning based on the selected archiving standard (PDF/A-1 / PDF/A-2 / PDF/A-3):
- Fully embeds all fonts inside the PDF to prevent missing characters.
- Standardizes image color profiles for long-term archival color preservation.
- Controls embedded attachments per standard: PDF/A-1 prohibits, PDF/A-2 limited support, PDF/A-3 full support.
3. 3. Archive Structure Reconstruction: Rewrites the underlying PDF data stream per ISO PDF/A standards, adding archive identifiers, read-only permission locks, and long-term compatible page trees and index structures.
4. 4. Archive PDF Local Export: After standardization, packages the PDF/A archive file locally in the browser. One-click download without modifying the original PDF.
