Free Online File Viewer —
PDF, HEIC, Excel, CSV, Word, JSON & SQLite
The most-searched “viewer online” queries in 2026 are PDF viewer, HEIC viewer (iPhone photos on Windows), Excel / CSV viewer, DOCX viewer, JSON viewer and SQLite viewer. This hub also opens PPTX, ZIP, EPUB, XML, YAML, GPX, VCF, EML and Jupyter notebooks — without the upload that GroupDocs, Aspose and Smallpdf require.
100% client-side. Sort spreadsheet columns, run SQLite SELECT, expand JSON trees, peek ZIP contents, save HEIC as JPG. No login, no watermark, no 3-files-per-day cap.
Why this viewer beats popular online tools
Auto-detects the format
One drop zone for PDF, HEIC, XLSX, CSV, DOCX, JSON, ZIP, SQLite. We pick the engine.
No upload vs GroupDocs
GroupDocs (3/day, 20 MB), Aspose and Smallpdf (2/day) send the file to a server. This one never does.
HEIC on Windows
iPhone photos open here. Export JPG or PNG without installing codecs.
Sort, filter, column stats
Click a header to sort. CSV delimiter auto-detect. Sum / avg / min / max on numeric columns.
JSON tree, raw, table
Validate, pretty-print, minify. Arrays of objects become a spreadsheet. Copy paths.
SQLite + ZIP peek
Browse .db / .sqlite tables and run SELECT. Open a file inside a ZIP without extracting the archive.
How to View PDF, HEIC, Excel or Word Online Free
- Drop the file — or paste with Ctrl+V — nothing is uploaded. Try a sample if you just want to see the UI.
- We detect PDF, HEIC, XLSX, CSV, DOCX, JSON, ZIP, SQLite…
- Search, sort or run SQL — filter rows, jump PDF pages, expand JSON, query a database.
- Export or print — HEIC→JPG, CSV→JSON, DOCX→HTML, copy table, print the page.
Pro tip: Windows still hates HEIC. Drop the iPhone photo here and download JPG. European CSVs using ; are auto-detected. Paste JSON from the clipboard with Ctrl+V.

Google Docs viewer, GroupDocs, Aspose and Smallpdf upload. Dedicated HEIC sites often convert on a server. ViewAnyFile is private but thin on spreadsheet stats. This hub keeps every format on-device and adds sort, SQL and export.
