In-depth guide

PDF metadata editor guide

View and edit PDF document metadata fields locally in your browser. This tool is designed for fast local processing and practical day-to-day use.

Quick start

Input tips

Use one value per line for structured inputs. Common separators are handled gracefully.

Privacy

Processing runs in your browser tab for the MVP workflow, with no mandatory upload step.

When to use it vs alternatives

Use this tool when you need a fast, one-off PDF task and want the document to stay in your browser. Desktop editors or command-line tools are better for heavily encrypted files, regulated review workflows, or very large batch jobs that need repeatable automation.

Common pitfalls

Password-protected, digitally signed, or archival PDFs may need a specialist workflow before editing.
Large scans can use a lot of memory, especially on phones or older laptops.
Check the downloaded file before replacing the original, because compression, OCR, or conversion can change visual details.

Yes. Processing runs client-side for this tool's MVP flow.
