Getting started.

01. Install or extract.

The Windows installer is the easiest way to get started. Download it from the download section, open the file, review the publisher in Windows, and choose Install. Launch the app from Start. Use Windows 10 version 2004 (build 19041) or later, or Windows 11, on an x64 PC. Everything needed to run the app is included.

Prefer a portable copy? Extract the entire ZIP into a normal writable folder. Keep Tools, its subfolders, and the supplied files beside PhotoTimeFixer.exe. Do not run inside the ZIP or move only the executable. The complete download includes the tools used to compare photos on your computer.

Explorer integration is available only in the portable edition. Use its Explorer integration screen or Install.cmd to install a per-user right-click command. On Windows 11 it appears under Show more options. The website MSIX and Store editions do not register an Explorer menu; use Open folder, Add images, or drag-and-drop instead.

Website releases are updated by downloading a newer version; this MSIX download does not provide automatic updates. Close any running copy before updating. Switching between portable and packaged editions may isolate preferences, history, and your saved OpenRouter connection. Do not assume those transfer automatically. Retain the original history and photo backup folders, and reconnect AI in the edition you use if needed.

02. Open your photos.

Use Open folder to replace the workspace, Add images to add files, or drag photos and folders into the app. Folder imports include subfolders. Removing a row or clearing the workspace never deletes a photo.

Start with a small set of copies while learning. Some file types allow fewer saved details to be changed, and not every RAW file has a usable preview. Separate XMP sidecars and videos are not included.

03. Fix camera times.

Open Sync Camera Times. Name your photographers and cameras, then choose the folder or detected camera for each one. Check these assignments: camera information cannot tell the app who took a photo. The same photo cannot be assigned to overlapping camera groups.

Choose the camera whose time you want to keep. It stays fixed. Move each other camera’s times earlier or later by the number of hours, minutes, and seconds needed. Optional AI suggestions help you get started; check the chosen photos and adjust the time yourself.

Select only the corrections you want. Preview the changes, compare old and new times, then apply. The app moves each camera’s times by one fixed amount. It does not automatically work out time zones or follow a clock that gradually gains or loses time.

If you choose optional AI assistance

Connect your own OpenRouter account from AI connection. You need internet access, a usable key, and provider credits. Upload consent is off until you enable it for an analysis. Selected upright JPEG previews have a maximum edge of 768 pixels and are stripped of metadata before being sent to Liquid through OpenRouter. Read the privacy notice before using photographs of people or private events.

04. Check photo details.

Open Photo Details to see the date taken, camera, lens, and other information saved with a photo. You can filter the list by camera, lens, filename, or other details. Select the photos you want to change. Changing filters clears your selection so hidden photos are not included accidentally.

Choose Edit selected photos. Depending on the file, you can change a date, add a caption or copyright, adjust a number, or remove a detail. Use the combined date-and-time fields to keep existing fractions of a second and time-zone offsets. Advanced note: separate EXIF and XMP copies of a detail are not automatically kept in sync.

Build exact preview tests your changes on full temporary copies first. Compare the result and read any notes before applying. Some details are read-only, and what you can change depends on the file.

05. Rename your photos.

Enter a name, choose how to number the files, and check the starting number. Sort by time taken, filename, camera, or another available detail. You can also group photos by camera.

Review proposed filenames before choosing Rename images. Invalid names, duplicates, and occupied destinations are blocked. Files stay in their existing folders. Undo last rename checks hashes and applies to the latest completed rename batch only.

Keep your originals and backups.

Change previews use hidden .ExifExpert/staging photo folders. Applying retains full originals in .ExifExpert/backups. Allow approximately one extra full copy of selected photos; repeated batches retain more versions. There is no automatic backup cleanup.

History & restore lets you check a restore before returning a saved group of photos to its original details. Restore newer edits to the same files first. Moving or renaming photos after editing can prevent restoration until they are back in the original folders with their original names. Keep hidden photo-folder backups and local history while you need them.

Preferences, journals, analysis reports, caches, and the encrypted optional AI key use %LOCALAPPDATA%\ExifExpert. Let an Apply operation finish. If interrupted, use Recover interrupted edit. Uninstalling the app does not automatically remove photo backups.
