Part 6 of 7 · Settings & reference
Settings
Six controls sit between the list and the Convert button. Only the output folder is remembered between sessions; the rest fall back to their defaults each time you start the app.
| Control | What it does | Default |
|---|---|---|
| Output Folder | Destination for the batch. … picks a new one; Open Output Folder opens the current one in Explorer. | Pictures · remembered |
| Format | Extension applied to every output file in the run. | .jpeg |
| Open folder after convert | Opens the output folder in Explorer when a run finishes. | On |
| Save EXIF info | Keeps EXIF / XMP / IPTC metadata in the converted file. The colour profile is always kept. | On |
| Quality | JPEG / JPG output quality, 1–100. Greyed out for every other format. | 90 |
| Reset | Puts the quality back to 90. Visible but greyed out while you are already at 90. | — |
Show EXIF sits next to Save EXIF info because it is about the same subject, but it is not a setting: it opens a read-only window (see EXIF info).
Why quality is disabled for most formats. PNG and TIFF are lossless — a “quality” number would silently change the compression level, not the picture. BMP, GIF, SVG and XPM have no quality parameter at all. Rather than let the slider pretend, it is greyed out.
Supported formats
In: .heic and .heif. Nothing else is accepted, and there is no “convert to HEIC” direction — HEIC is input only.
| Output | Compression | Quality slider | Good for |
|---|---|---|---|
| .jpeg | Lossy | Yes | The default. Photos for sharing, email, any Windows or Android app. |
| .jpg | Lossy | Yes | Same encoder as JPEG; the extension some upload forms insist on. |
| .png | Lossless | No | Screenshots, text, flat colour, transparency-friendly workflows. |
| .bmp | None | No | Maximum compatibility for odd legacy tools. Very large files. |
| .tiff | Lossless | No | Archiving and print pipelines that expect TIFF. |
| .gif | Lossy palette | No | The 256-colour case: where a GIF is explicitly required. |
| .svg | Wrapper | No | Placing the photo in vector layouts; the pixels are embedded, not re-drawn. |
| .xpm | Text | No | X11 / legacy Unix assets. |
The output file always keeps the source base name and gets the chosen extension, written into the output folder. See Where the files go for the collision rule.
Shortcut reference
