Managing large photo collections just got a lot easier.

Rename Multiple Photos in Seconds​

With the new Batch Rename feature in v0.7.7 or later, you can now rename multiple photos at once using flexible, powerful patterns — with a live preview before anything is changed. No more manual renaming, no more mistakes, and no more guesswork.

Why Batch Rename?​

If you’ve ever returned from a trip, photoshoot, or event with dozens (or hundreds) of photos named something like:

DSC03746.JPG
DSC03747.JPG
DSC03748.JPG

you know how quickly things become unmanageable.

Batch Rename lets you bring structure and consistency to your files in one simple action.

How It Works​

1. Select Your Photos​

Choose one or more photos in the archive.

2. Open “Rename Photos”​

Open the More menu and select Rename by date and time. (The option only appears when files are selected.)

3. Define a Rename Pattern​

Enter a pattern using placeholders for dates, filenames, and sequence numbers.

For example:

{yyyy}{MM}{dd}_{HH}{mm}{ss}_{filenamebase}.{ext}

4. Preview Before Applying​

Click Preview to see exactly how your files will be renamed.

  • First and last items are shown
  • Errors are highlighted per file
  • No changes are made yet

5. Rename with Confidence​

If everything looks good, click Rename to apply the changes instantly.

Powerful Pattern Support​

Batch Rename supports a rich set of placeholders so you can create meaningful filenames.

Date & Time​

  • {yyyy} – year
  • {MM} – month
  • {dd} – day
  • {HH}, {mm}, {ss} – time

Filename​

  • {filenamebase} – original filename
  • {ext} – file extension

Sequence Numbers​

  • {seqn} – incremental number
  • {seqn:N} – padded sequence (e.g. {seqn:3} → 001)

Preview & Error Handling​

One of the most important parts of Batch Rename is safety.

  • Every rename is validated during preview
  • File-specific errors are shown clearly
  • Renaming is blocked until all errors are resolved

This ensures you always know exactly what will happen before committing changes.

Recent Patterns, Automatically Saved​

Your most recently used rename patterns are automatically saved locally and available in a dropdown the next time you open the modal.

  • Up to 10 recent patterns
  • Stored in your browser
  • No manual saving required

Perfect for recurring workflows.

Designed for Every Device​

Batch Rename is built with usability in mind:

  • Fully responsive (desktop & mobile)
  • Dark mode support
  • Keyboard accessible
  • Available in English, Dutch, and German

Try It Out​

Select a few photos, open the menu, and give Batch Rename a try. It’s a small feature that saves a surprising amount of time — especially if you care about clean, meaningful filenames.
