Omni Viewer Docs
Omni Viewer is a browser-based file viewer designed for quick inspection of many file types. This page explains when the viewer is useful, what kinds of files fit the workflow well, and what limitations users should keep in mind.
How to quickly merge two PDFs in the browser
When you receive multiple PDFs that need to be checked together, a browser-based workflow can save time. Omni Viewer supports a quick merge-oriented flow for reviewing and combining two PDF files without installing a separate desktop tool.
This is especially useful for reports, scanned attachments, and split presentation exports. For final submission, it is still a good idea to review the merged result once more, especially when the source documents contain unusual restrictions or complex layouts.
How to inspect HWP and HWPX files without native software
Korean office formats can be difficult to open when a dedicated application is not available. Omni Viewer is intended to make first-pass inspection of HWP and HWPX documents easier directly in the browser.
It is well suited for reading document content, checking paragraphs and tables, and understanding the overall structure. However, it should be treated as a practical inspection tool rather than a guarantee of pixel-perfect rendering in every advanced document case.
How to preview CSV and Excel files safely on the web
Data files are often easier to validate when you can inspect them as tables before opening them in a heavier desktop workflow. Omni Viewer provides quick table-oriented views for CSV, TSV, XLSX, and XLS files with search, sorting, and sheet switching.
This makes it useful for validation and first-pass review rather than full spreadsheet authoring. In practice, it works best when you want to verify columns, inspect values, and confirm that a received file looks structurally correct.
What to know when opening Word and PowerPoint files in the browser
Browser-based document previews are useful when you need to review content quickly without launching office software. Omni Viewer focuses on readable text, document structure, tables, and slide-by-slide content review for these formats.
Some advanced layout details, fonts, spacing, or animation behavior may differ from the original environment. That means the viewer is strong for review and inspection, while final visual verification may still belong in the source authoring tool.
When quick review matters for images, PSD, and audio files
Design assets and media files often need fast inspection before deeper editing begins. Omni Viewer supports workflows such as image zooming, PSD layer inspection, and audio waveform-based listening directly on the web.
That makes it practical for early review, triage, and quick feedback. It is less about replacing specialist production software and more about removing friction from the first step of file inspection.
Notes about file handling and share links
Standard viewing flows are designed to prioritize in-browser handling whenever possible. Files may only be uploaded in limited cases when a share link needs to be created and delivered.
This distinction matters for users who want the convenience of web-based inspection while still understanding when a file stays local and when sharing introduces an upload step. For sensitive documents, that difference should be considered before using a share workflow.
