5. Rename All PDFs in One Click
Once the names look good, click Rename All to apply them instantly.
Using Custom Instructions for Consistent PDF Naming
If you want even more control over how your PDFs are named, you can create your own pattern using Custom Instructions. This feature lets you define a naming format that AI Renamer will follow for every file in the batch.
For example, if you want your files to follow a structure like:
client - file title - date
you can write a simple instruction such as:
“Name each file using this format: {client}-{title}-{date in YYYY-MM-DD format}.”
AI Renamer will generate names that match your pattern based on what it detects inside each PDF.
Before and After Example
Before:
scan_001.pdf
Document (14).pdf
Custom Instruction Used:
“Use this format: {client}-{title}-{date in YYYY-MM-DD format}.”
After:
ABC_Corp-Invoice-2025-01-12.pdf
IRS-TaxForm-W9-2024-03-10.pdf
You can capture a screenshot of your Custom Instructions box and the before/after rename preview to show how it works.
