Saving Captures
Save the current capture (with annotations rendered in) to a file on disk.
Quick Workflow
- Take or load a capture so the canvas is populated.
- Click Save on the toolbar, or press
Ctrl+S. - Choose a folder and filename in the dialog.
- Pick a format from the Save as type list.
- Click Save.
The command is only enabled while HasCapture == true. With an empty canvas the toolbar button is greyed out.
Default Folder and Filename
The file dialog opens at Save.SaveFolder. If that setting is empty, it falls back to %USERPROFILE%\Pictures\Tex\ and creates the folder on first save.
Filenames are pre-filled from Save.FileNamePattern. The default template is tex_{timestamp} which resolves to e.g. tex_20260418_153042.
Setting — clear Save.SaveFolder to always return to Pictures\Tex, or point it at a shared project drive to keep captures in one place.
Supported Formats
| Format | Setting(s) | Notes |
|---|---|---|
| PNG | Save.PngCompressionLevel (0-9, default 6) | Lossless. Preserves transparency. |
| JPEG | Save.JpegQuality (0-100, default 90) | Lossy. No transparency. |
| BMP | none | Uncompressed. Largest files. |
| WebP | Save.WebPQuality (1-100, default 85), Save.WebPLossless (default false) | Smallest files at acceptable quality. |
PNG compression level trades speed for file size — 0 is fast and large, 9 is slow and small. Image quality is identical either way (PNG is lossless).
Metadata and Resizing
| Setting | Default | Effect |
|---|---|---|
Save.StripMetadata | false | Removes EXIF and similar tags before writing. |
Save.ResizeOnSave | false | Downscale oversized captures on save. |
Save.MaxWidth | 1920 | Cap width in pixels when resizing. |
Save.MaxHeight | 1080 | Cap height in pixels when resizing. |
Save.MaintainAspectRatio | true | Scale proportionally inside the max box. |
Resizing only shrinks — captures smaller than the max box are written at their native resolution.
Tip — for sharing to chat apps (Slack, Teams, WhatsApp), WebP at quality 85 produces tiny files that still look clean. For print or documentation that will be zoomed in, save as PNG to avoid compression artefacts.
