Internal viewer: text and hex

The internal viewer shows any file as text or as hex. Text files with a UTF-8 or UTF-16 byte-order mark open decoded, and F8 cycles through code pages for older files. F4 or Ctrl+H switches to hex, which always shows the raw bytes.

• Find text forward and backward (F7, then F3 for the next match), with regular expressions or as hex byte sequences.
• Select with the mouse or keyboard and copy to the clipboard or to a new file.
• Wrap long lines, go to an offset, view full screen.
• Step to the previous or next file of the panel, or of the Find results, without closing the viewer.

PictView: images

PictView opens pictures with Windows Imaging Component: JPEG, PNG, GIF (animated too), BMP, TIFF with all its pages, ICO, JPEG XR, DDS, and every format whose codec is installed on your PC, such as HEIF, AVIF, WebP and camera RAW. It also makes the thumbnails in Sally's panels.

• Zoom, fit to the window or its width, full screen, and Space for the next picture of the panel.
• Rotate, flip, crop to a selection and save in another format; print with a page preview.
• Image properties, EXIF data in words, a histogram, and a color picker with RGB values.
• Copy to the clipboard, set as wallpaper, capture the screen, and update the thumbnail stored in JPEG files.
• From 1.0.37, toolbar, menu and status icons scale with Sally's display sizing, including the histogram toolbar.

Web Viewer: HTML, Markdown, SVG

The Web Viewer uses Microsoft Edge WebView2 to render HTML, XML, SVG and images. Markdown files render with GitHub-style formatting and their images, so a README.md looks the way it does on GitHub.

Viewers and editors are chosen by file mask under Options › Configuration › Viewers and Editors, so you can also send a type to any external program.
