Step 01

Open

Find the settings page

Renma stores every setting locally in Chrome. To reach the panel, go to chrome://extensions, click Details on Renma, then Extension options.

Shortcut: right-click the toolbar icon and pick Options.

Or right-click the Renma toolbar icon → Options.

Step 02

Behavior

Flip the master switches

Three switches govern the whole extension. The master toggle pauses renaming globally — useful when you're doing a bulk download and want the original names.

Only images restricts Renma to actual image MIME types. Notifications shows a small desktop toast so you can spot what got renamed to what.

  1. 1Master on/off — pause Renma without uninstalling.
  2. 2Only images — skip PDFs, ZIPs and other file types.
  3. 3Notifications — desktop toast on every rename.
Step 03

Template

Design the filename

The template controls every renamed file. Click any token chip to insert it at your cursor — common combos:

  • · {prefix}_{timestamp}.{ext}
  • · {prefix}-{date}-{counter}.{ext}
  • · {prefix}_{dimensions}.{ext}

  2. 2Live preview — what a real Unsplash download would look like.
Step 04

Rules

Teach it your domains

Renma ships with sensible defaults (OpenAI → AI_Generated, etc.). Add your own to route specific sites into named prefixes and folders.

Example: dribbble.com → Dribbble → refs/ui.

Domain rules

  1. 1Domain — match on any part of the URL host.
  2. 2Prefix — becomes {prefix} in the template.
  3. 3Folder — optional subfolder inside Downloads/.
Step 05

Scope

Pick where Renma runs

Use Whitelist when you only want Renma on a handful of sources. Use Blacklist to keep your bank's downloads untouched. All sites is the default and works for most people.

Site scope

  1. 1Mode: run everywhere, only listed sites, or exclude listed sites.
  2. 2Site list — one domain per chip.
Step 06

Insights

Duplicates & stats

Tag keeps duplicate downloads but marks them in the popup so you can spot repeats. Skip refuses to re-download the same URL entirely.

The stats panel is fully local — nothing leaves your machine. Hit Reset to zero it any time.

Portable

Backup & restore

Moving to a new laptop? Export once, import on the other side. Templates, rules, scope, duplicate mode and toggles all travel together.
