Add sequential numbers to a group of files
The Numbering panel creates an ordered sequence for selected files, optionally with leading zeros.
Numbering guides
Create ordered names with padding, sorting and controlled sequences.
Quick answer: Numbering depends on the file list order. Choose a start, increment and padding, then inspect the first and last generated names.
Task-by-task guides
Add leading zeros to filenames
Use numeric padding so alphabetical sorting matches intended numeric order.
Start filename numbering at a custom value
The Numbering panel can start at 100 or another value instead of one.
Number files in increments rather than one
Numbering can use a custom increment to leave gaps for future insertions.
Rename images in chronological sort order
Sort the file list by the relevant timestamp before assigning sequential numbers for archives.
Replace outdated numbering in filenames
Remove the old prefix or suffix first, then generate a new number range from the intended sort order.
Rename photos as 001, 002, 003
Apply a fixed base name with three-digit numbering to obtain consistent photo names.
Keep original names and append a sequence
Retain descriptive stems and append a numeric suffix to make duplicates distinguishable.
