Update and sanitize your document information online using PDFMount's metadata editor. The processing engine parses the underlying PDF file structure, targeting the document information dictionary and metadata streams to update key attributes like title, author, subject, and keywords. Unlike tools that modify the layout pages, our utility writes directly to the file header metadata, ensuring that visual elements, vector assets, and original fonts remain untouched. The entire process runs on secure, isolated server nodes, keeping your private papers confidential. You can clean tracking metadata and personalize your files in seconds from any modern browser without installing software. Let our utility clean document properties today. Let it update your data now.
Guest users can upload and edit PDF metadata up to a maximum file size limit of 25MB per file. Free registered accounts are granted uploads of up to 50MB per file, while Pro subscribers can upload files up to 500MB. Our system has no page count limitations and processes files of all sizes in under ten seconds. The editing engine processes tasks quickly.
No, our editor only targets the document information dictionary and metadata stream headers inside the file. The actual visual pages, text coordinates, vector graphics, and embedded fonts remain completely untouched. This ensures layout fidelity across all devices without any changes. Your document remains fully searchable, readable, and zoomable.
PDF files often contain hidden tracking data such as original author names, creation software types, local username details, and directory paths. Cleaning this metadata prevents the accidental exposure of private directories or internal business software details before public distribution. This is crucial for maintaining corporate security and protecting individual privacy. The editor allows you to sanitize these properties in seconds.
No, PDFMount maintains a strict policy against injecting watermarks or promotional logos onto client files. The output PDF remains clean and matches your original formatting exactly. Only the metadata properties you configured will be updated in the file header. The document remains fully ready for professional presentations, academic submissions, or business contracts.
We implement advanced encryption protocols using TLS 1.3 to safeguard all data transfers. The metadata editing process is executed on isolated sandbox containers to prevent access by unauthorized third parties. All files are purged from our secure, volatile cache exactly 60 minutes after processing finishes. We do not keep logs or backup files of your sensitive records.
Our metadata editor operates by modifying the Document Information Dictionary and the Extensible Metadata Platform (XMP) streams in the PDF file structure. By targeting the metadata dictionary directly, the engine changes document fields without re-saving page content objects, preserving layout fidelity and preventing font subset corruption. Embedded graphics and text arrays are not compressed or rasterized, ensuring that original file DPI and image scaling remain intact. This technical approach guarantees that the document continues to conform to PDF specifications.
Data privacy is a core component of the PDFMount architecture. Every metadata modification task is processed inside an isolated virtual sandbox container that has no persistent storage access. We enforce a strict zero retention policy, meaning we do not inspect, copy, or log your files. All source PDFs and updated outputs are permanently purged from our volatile server caches exactly 60 minutes after processing. This automatic deletion routine ensures complete confidentiality for your corporate papers and private files.
This metadata editor supports a wide range of professional, administrative, and academic needs. Businesses use the tool to sanitize corporate reports, removing local directory paths and username metadata before external distribution. Legal professionals can clear author details from trial briefs to ensure compliance with court filing rules. Academic researchers can update keyword lists and author fields before submitting papers to online journals. PDFMount provides a free, fast, browser-native utility that replaces expensive desktop software.
