OnlineDocumentViewer.com now covers PDF, the Microsoft Office families (DOCX, XLSX, PPTX), the common image formats (PNG, JPG) and AutoCAD drawings. Here is what each part takes.
Free PDF viewer
Upload a PDF up to 25 MB at the PDF viewer. Page forward and back, jump to a page number, zoom, fit to the window, print. Text PDFs can be searched; scanned ones cannot, because each page is an image and there is no OCR here. Nothing to download, nothing to install.
Microsoft documents
Word takes nine extensions up to 15 MB. Excel takes eight up to 20 MB, showing every sheet, merged cells, number formats and embedded charts, with formula cells displaying their results. PowerPoint takes nine up to 20 MB. Macro-enabled files render; nothing inside them executes.
Images
Common formats — JPG, PNG, GIF, BMP, WebP, AVIF — up to 25 MB, and the vector and raw viewer adds TIFF, SVG, ICO, DNG, CDR, CMX, TGA, EPS, EMF, WMF and JP2 at the same ceiling. PSD has its own page, also 25 MB.
Free CAD viewer
DWG, DXF and DGN open at the CAD viewer, up to 10 MB, with layers you can switch off one at a time and full-precision zoom. No AutoCAD licence, and nothing to install for the people who only need to look at the drawing.
A fixed catalogue, not universal support
Online Document Viewer opens 70+ extensions: PDF, the Microsoft Office families, AutoCAD drawings (DWG, DXF, DGN), email, PSD and the image formats. It is a fixed list — if an extension is not on it, the upload box refuses the file and says so.
Anywhere, with nothing kept
Rendering happens on the server, so any device with a browser will do. The file is deleted after viewing, there is no account, and there is no sharing link: each person opens the copy they already have.
