What you can open
Stuff prioritizes viewing. Agents and your usual desktop apps can do heavier editing; originals remain available to download.
| Family | Current view | Editing or limits |
|---|---|---|
| Markdown, plain text, code | Formatted Markdown or readable source | Small text can be edited; code is never executed |
| JSON, CSV, TSV | JSON tree or tables | Bounded previews; original download preserves all data |
| Pages and zoom | No PDF editing or OCR | |
| Images | Browser image view | Browser codec support varies; no HEIC conversion |
| DOCX, PPTX | Converted pages/slides | Static preview; fonts can differ, no Office editing or animations |
| XLSX | Sheet tabs and cells | Cached values and formula text; no recalculation, chart or pivot rendering |
| Audio and video | Native playback or a converted preview where supported | Processing can take time; source stays unchanged |
| GLB, embedded glTF, STL, OBJ | Orbit, pan, zoom, wireframe; supported animation | Self-contained assets; external texture dependencies are not fetched |
| HTML slides | Slide navigation, notes and presentation view | Uploaded scripts do not run |
| HTML | Sandboxed static view | No uploaded scripts or network access |
| ZIP | Archive listing | No extraction in the browser |
| Other types | File information and download | Native Blender/design files, ebooks and additional document formats need future viewers |
The current per-file limit is 25 MiB. Text previews are limited to 2 MiB and text editing to 1 MiB. Spreadsheet and archive previews deliberately show bounded subsets; a partial preview does not mean the original was truncated.
Uploaded files are checked before serving. A processing or unsupported-format message is not a promise that conversion will succeed. You can return to a file after processing finishes.
Markdown supports internal file links and images stored in Stuff. Those images still go through file permissions. Arbitrary remote images are not embedded by the Markdown viewer.
