Clean Up Downloaded Image Filenames — Bulk Image Downloader Pro

URL-derived filenames arrive with baggage: CDN prefixes, double underscores, query-string fragments, and vendor tags you never wanted in a folder. Clean up downloaded image filenames at save time by stacking find-and-replace rules after the Filename Constructor builds each name.

Bulk Image Downloader Pro applies cleanup on every file in a task before Chrome writes it to disk.

Step 1: build the base name first

Start in the Filename Constructor with the pattern you want—URL tokens, domain segments, Sequence numbers, timestamps, or Custom Filenames from File. Cleanup is the polishing pass, not the naming plan. Constructor decides structure; cleanup removes junk the source URL dragged in.

Step 2: enable Filename Cleanup on the task

Turn on Filename Cleanup inside the constructor panel for the task. Click Add rule for each transformation you need. Each rule has:

  • Contains — text to find in the filename (matched case-insensitively)
  • Replace with — replacement text (leave empty to remove the match)

Rules run in order, top to bottom, on every filename in the batch.

Step 3: stack rules for messy sources

One rule rarely fixes a noisy CDN export. A typical stack:

  1. remove a repeated prefix such as cdn-prod_
  2. replace __ with a single hyphen
  3. drop a trailing tag such as __main

Example: cdn-prod_SKU1234__main.jpg becomes SKU1234.jpg across hundreds of files with zero post-download renaming.

Step 4: pair cleanup with export and CSV workflows

Cleanup settings serialize into Export Tasks CSV (schema v4 Filename Cleanup Rules column) so recurring jobs keep the same rules. They also run after custom filename lists from CSV when both features are enabled on a task.

Step 5: what cleanup does not do

  • rename files already sitting in your Downloads folder from past jobs
  • change image pixels, dimensions, or format—use resize or convert settings for that (mutually exclusive per task)
  • fix broken URLs or redirect chains—validate lists with the 404 and redirect checkers first

Cleanup only tidies the filename string the constructor (or custom list) produced.

For token-based naming patterns, see filename constructor tokens and sequence. Install Bulk Image Downloader Pro and set cleanup once per task instead of bulk-renaming after every download.
