A few things to know
- Viewing and editing are different. A working preview does not mean that format has a built-in editor. You or an AI agent can download an original, edit it with an appropriate tool, and save a new version.
- Originals stay intact. Converted Office and media previews are viewing copies; the original file remains available to download.
- Some previews take time. Files must finish their checks, and some formats require conversion. Codec support and preview limits can affect individual files.
- Office previews have limits. Fonts may differ. PowerPoint previews are static, and Excel previews do not recalculate formulas or reproduce every chart or pivot table.
- HTML is sandboxed. Uploaded scripts do not run. Source-code samples are displayed, not executed.
- 3D models should be self-contained. External texture and model dependencies are not fetched.
- This is a public gallery. Use your own space for personal files and experiments.
