Files stay in this browser. Maximum 20 files, 20 MB per file, 100 MB total, and 16 million decoded pixels per image.
Instructions
- Choose files.
- Set a filename prefix and starting number.
- Review the old and new names, then download the ZIP.
Understanding your result
A prefix such as workshop-photo and a starting number of 1 gives the selected copies a consistent numbered series. Review each old/new pair before downloading the ZIP. The names describe the selected order; they do not sort photos by their content or capture date.
What to do if you have a problem
If the order is wrong, review the selected files before creating your copies. Change Filename prefix or Starting number and click Preview filenames again. Extract the downloaded ZIP into a folder where you can compare the new copies with your originals before using them elsewhere.
What to know before using the result
The ZIP contains copies. This page cannot rename files in your original folders.
Files and text are held in this page while you work. Downloads are saved through your browser. Reloading or closing the tab clears the working page; a downloaded copy remains in your device's download location.
Summary
