Open common files with purpose-built viewers

What you can do here

Inspect ZIP, 7Z, RAR, PPTX, EPUB, SVG, HEIC, fonts, binary files, metadata, JSONL, YAML, SQL, logs, large text, CSV, TSV, Excel, DOCX, PDF, JSON, XML, Markdown, HTML, text and code with a viewer designed for the format.

How to choose the right tool

Viewers are intended for safe inspection rather than full native editing. Large-file tools use bounded windows where appropriate, archive extraction blocks unsafe paths, and complex layout should still be checked in the original desktop application when exact fidelity matters.

Check the finished result

Use the browser preview for inspection and triage, but verify exact layout, macros, embedded objects, signatures or print behavior in the format’s native application when required.
