MPViewer 1.3 makes folder-first photo review faster, clearer and safer—from the first rating pass to verified import and export.

The highlightsMove through the work,
Move through the work,
not around it.
The biggest changes in 1.3 reduce friction in review, make active state easier to understand and protect multi-file operations.
Choose your RAW preview.
Prefer the camera’s embedded JPEG for a fast, familiar preview—including its in-camera or Lightroom-style look—or switch back to MPViewer’s primary RAW decode. Your choice is remembered.
See what is active.
Active filters are summarized in the sidebar and status bar, with one-click Clear All. Rating filters now say “and above,” removing ambiguity from every filtered pass.

where you expect.
Adjustments, Effects and Annotations have separate tabs. The pencil button opens Annotations directly, and the new one-time Getting Started screen explains the essential folder-first workflow without getting in your way later.
Fullscreen can keep the filename and position visible—such as 124 / 890 IMG_2345.CR2—so long review sessions never lose their context.

the stakes are real.
Rename as one transaction.
If staging or destination rename fails, MPViewer rolls the operation back instead of leaving hidden temporary files. MPViewer edit sidecars and conventional metadata XMP sidecars move with the photograph.
No partial backup surprises.
When an optional backup copy fails, MPViewer rolls back that file’s primary copy. Verification can use SHA-256 for stronger confidence when moving photographs off a card or drive.
Know—and restore—your handlers.
Settings reports the current default handlers for supported formats and can restore the handlers remembered before MPViewer was selected.
Under the hoodFaster when you move.
Faster when you move.
Lighter when you zoom.
High-quality RAW rendering no longer blocks navigation to the next photograph, and nearby-image preloading keeps rapid browsing responsive. Fullscreen zoom now uses a viewport-sized Core Animation surface, avoiding the extreme memory spikes that could occur at very high zoom.
Finder “Open With” bursts are queued safely, Geotag Map loading is bounded and cancellable, video failures show an actionable message, and keyboard events stay out of sheets, dialogs and text fields.
