How to use free document viewer
Choose a supported document from your device. Its bytes are read directly by this browser tab.
The viewer selects the matching local parser: PDF renderer, spreadsheet grid, Office package reader, ebook reader, or safe text decoder.
Move between PDF pages, slides, document sections, or workbook sheets; search extracted text and spreadsheet values locally.
Clear the file when finished. The read-only preview is discarded from the tab and nothing has been uploaded.
What this tool does
- Real PDF page rendering with page navigation and zoom
- Read-only XLSX, XLS, XLSM, ODS, CSV, and TSV grids with sheet tabs
- DOCX, ODT, PPTX, and EPUB text reconstruction without running embedded content
- Safe plain-text viewing for TXT, Markdown, HTML, JSON, and XML
- Search across extracted document text or loaded spreadsheet cells
- Hidden and very-hidden spreadsheet sheets labelled for intentional review
- Macros, scripts, remote resources, forms, and embedded executables never run
How the result is verified
A preview is shown only after the relevant local parser accepts the file structure. PDF pages must render through PDF.js, spreadsheets must expose readable sheets, Office and ebook packages must contain their required document parts, and text is decoded as inert content. Reconstructed layout limitations remain explicitly labelled.
Frequently asked questions
Can I open a Word document without Microsoft Word?
Yes for DOCX files. The viewer extracts readable paragraphs and explicit page sections locally. It does not claim pixel-perfect Word layout, and legacy .doc files must first be saved as DOCX.
Can this open CSV and Excel files?
Yes. CSV, TSV, XLSX, XLS, XLSM, ODS, and common spreadsheet structures open as read-only grids. Workbook sheets are shown as tabs, including labelled hidden and very-hidden sheets.
Does the viewer execute macros or HTML scripts?
No. Spreadsheet macros are detected but never run. HTML and ebook scripts, forms, styles, links, and remote resources are not executed; the viewer displays extracted inert text only.
Is my file uploaded to a server?
No. The file is opened with your browser's File API and processed by code running in your tab. You can confirm this yourself: open your browser's developer tools, watch the Network panel, and process a file — no request carries your file's bytes. See our How it works page for a step-by-step verification guide.
Is there a file size limit?
There is no artificial upload limit because there is no upload. Practical capacity depends on your device's memory and your browser. Very large files may be slow or fail to decode on low-memory devices; if that happens the tool fails safely without altering your original file.
