Rename PDF from Content Online Free — Auto Renamer

The template builder lets you combine multiple fields into a filename pattern. For example, {date} - {regex} creates filenames like '2024-01-15 - INV-12345'. Click field chips to insert them at the cursor.

Zones let you draw rectangles on the PDF page to extract text from specific areas. This is ideal for invoices where the vendor name is always in the top-right and the invoice number is in a header. Use {zone1}, {zone2} in your template.

Any JavaScript regex. Use capture groups for precise extraction: INV-(\d+) extracts just the number. Without groups, the full match is used. Common patterns: \d{4,} (4+ digit numbers), [A-Z]{2}-\d+ (codes like AB-123).

Only if the PDF has a text layer. The tool detects files with no text and shows a warning with a link to the OCR tool. Run OCR first, then rename.

Duplicates are highlighted in red with a 'DUP' badge. Use {n} in your template to add auto-incrementing counters (001, 002…) and prevent duplicates.

Yes. Click any auto-generated name to edit it. Manually edited names won't be overwritten when you change the template. Click 'reset' to revert to the template.

The tool extracts Title, Author, and Creation Date from the PDF info dictionary. Use {title}, {author}, and {created} in your template. Not all PDFs have metadata.

No. Everything runs 100% in your browser. Files are never uploaded. Batch download creates a ZIP archive locally.

There is no file count limit. You can upload and rename hundreds of PDFs in a single batch. All files are processed in your browser and downloaded as a ZIP archive. Unlike Sejda which caps at 5 files per task, WhiskFile has no restrictions.

The tool automatically detects 4 common date formats: YYYY-MM-DD, DD/MM/YYYY, 'Month Day, Year' (e.g., January 15, 2024), and 'Day Month Year' (e.g., 15 January 2024). The first date found in the text is used for the {date} field.

By default the tool extracts text from page 1 only for speed. Toggle 'All pages' in advanced settings to search across all pages (up to 3000 characters). This is useful when the information you need appears on page 2 or later.

Use the zone selector to draw rectangles around the vendor name and invoice number on your PDF. Then set your template to '{zone1} - {zone2}' or 'INV-{regex}' with a regex pattern like '\d{4,}' to extract the invoice number automatically.
