Editing
Edit… (E) opens the editor over the image: crop, turn and flip, then save the result as a new file. The original is untouched unless you choose it yourself in the save dialog.
Crop
Drag the crop box’s corners and edges, or drag inside it to move it. Below the image, Crop holds the box to a shape, or lets it go free:
Free · Original (the photo’s own shape) · Square · 5:4 · 4:3 · 3:2 · 16:9
A cycles through them. The arrow keys move the box; with Ctrl (⌘) they move its right or bottom edge instead, to resize it.
Turn and flip
| Key | Does |
|---|---|
| R | Rotate right |
| Shift+R | Rotate left |
| H | Flip horizontally |
| V | Flip vertically |
Each has a button too. The editor starts from the photo as you see it, already upright.
Undo
Every step can be undone and redone, Reset included:
| Key | Does |
|---|---|
| Ctrl+Z | Undo |
| Ctrl+Shift+Z or Ctrl+Y | Redo |
| Backspace | Reset to the photo as it was |
A drag is one step, recorded when you let go, and a run of arrow presses is one step too.
Save
Save… (Enter or Ctrl+S) asks where. It suggests the name with “(edited)” added, beside the original, in a format Mirada can write:
- JPEG, PNG, TIFF or BMP. A photo in HEIC, AVIF, JPEG XL or WebP is offered as JPEG or PNG.
- The file is written beside its target first and then moved over it, so a failed save never leaves half a file.
Esc or Cancel closes the editor without saving.
While the editor is open, nothing changes the image under it: stepping, trashing and renaming are turned away until it closes.
What a saved edit keeps
- The EXIF, into a JPEG or PNG: the camera, lens, exposure, date and location, from a JPEG, HEIC, AVIF, WebP, PNG or JPEG XL. It is patched rather than rebuilt: the orientation is set to upright and the size to the edit’s, the old embedded thumbnail is left out, and everything else, maker notes included, survives byte for byte.
- The colour profile, into a JPEG or PNG, so a wide-gamut photo (an iPhone’s Display P3, a camera’s Adobe RGB) does not save duller than it was in apps that manage colour. It is kept only while it still describes the pixels.
A BMP gets neither, as the format has nowhere to put them.
The editor works on a preview, so every step shows at once; the save applies the same edit to the full image.
