A PRACTICAL EXAMPLE
Know what a useful result looks like.
Export a collection with readable, predictable names.
Check before using the result
- Review the full name list before export.
- Check order with the move controls.
When the result needs work
Only ZIP entry names change. Your original device files are not renamed. Unsupported punctuation in the prefix is normalized for portable filenames.

Examples illustrate specific inputs and settings. Actual output size and appearance depend on your file and browser. Practice images are synthetic; they do not contain personal data.
GOOD TO KNOW
A few useful answers.
Does this change image quality or metadata?
No. Only the names inside the downloaded ZIP change. Original file bytes, image quality and any embedded metadata are preserved. Nothing is renamed on your device.
Can I control the order?
Yes. Move files up or down before downloading. Set a prefix, choose a starting number and one to six padding digits. Names use safe letters, numbers, hyphens and underscores, with extensions based on the actual file format.
Are my files uploaded?
No. Image files and results stay in your browser. This workspace does not send filenames or editing results to our server, and you do not need an account.
How many files can I use?
Choose up to 50 JPG, PNG or WebP files, no larger than 50 MB each and 100 MB combined. These tools preserve the original file bytes, rather than re-encoding the images.
