VaultPDF
Private PDF tools, right in your browser.
VaultPDF is the first Mesanix product: twelve focused tools for everyday document work, built so source files stay on the user's device.
Work with PDFs without handing them over
Many online PDF services begin by uploading a document to a remote server. VaultPDF takes a different approach. Its core workflows read, modify, render, and export files inside the browser, using the device that already holds the document. There is no account to create and no Mesanix document store to clear afterwards.
Choose the PDF task you need
Each tool has its own focused workspace. The links below open the live tool directly, so users can move from a specific document problem to the relevant workflow without searching through unrelated features.
- Merge PDFCombine several PDFs into one document in the order you choose.
- Split PDFDivide one PDF into smaller documents at selected points.
- Compress PDFReduce image-heavy PDF files while keeping the result readable.
- Rotate PDFCorrect the orientation of individual pages or an entire document.
- Remove PagesDelete pages you no longer need and export the remaining document.
- Rearrange PagesMove pages into a new order and export the reordered PDF.
- Extract PagesCreate a new PDF from only the pages you select.
- PDF to JPGRender selected PDF pages as JPG or PNG images.
- JPG to PDFArrange JPG and PNG images and turn them into a PDF.
- Add Page NumbersPlace configurable page numbers on all or part of a document.
- Add WatermarkApply a text watermark with custom placement and opacity.
- Sign PDFDraw, type, or import a signature and place it on PDF pages.
Which page workflow should you use?
Extract or remove
Extract Pages creates a new document from the pages you select. Remove Pages exports the original document without the pages you mark for deletion.
Rearrange or rotate
Rearrange Pages changes page sequence. Rotate PDFchanges page orientation without changing the sequence.
Convert or prepare
Conversion tools move between PDFs and images. Preparation tools handle compression, numbering, watermarks, and signatures before a document is saved or shared.
How local processing works
- The browser reads the file selected from the user's device. The source document is not submitted to a Mesanix upload endpoint.
- PDF parsing, page rendering, document changes, and export run in browser memory using the application code already loaded on the device.
- The completed PDF, image, or ZIP is handed to the browser's normal download, save, open, or share flow.
- Closing or reloading the workspace clears the active in-memory document state; VaultPDF does not provide a server-side document history.
Practical limits of browser-based PDF work
Device resources matter
Processing uses the current device's CPU and memory. Large, scanned, or image-heavy PDFs can take longer and may exceed the resources available to an older phone or a memory-constrained browser tab.
Some files cannot be processed
Corrupt, empty, unsupported, or password-protected inputs can be rejected. VaultPDF is designed to explain the problem rather than silently produce an incomplete document.
Downloads vary by browser
Desktop browsers usually download generated files directly. Mobile browsers, especially iPhone Safari, may open the result or use the device's Files or share interface instead.
Compression has trade-offs
Compression results depend on the source PDF. Image-heavy files offer the clearest opportunity for reduction, while already optimized or mostly vector documents may shrink very little.
Privacy model
- Core VaultPDF workflows do not send selected source documents to Mesanix or third-party services.
- No account or profile is required to process a document.
- Mesanix does not store a server-side copy of source files or generated outputs.
- The browser still requests the site resources needed to run the application, but the selected document is not included in those requests.
Designed for dependable browser use
VaultPDF checks inputs before processing, reports unsupported files clearly, and keeps each workflow focused on one document task. The product is reviewed on current desktop and mobile browsers, including direct tool links, generated downloads, and common browser-specific save behavior. Device and browser differences can still affect very large files, which is why the practical limits above are stated plainly.
