Frequently asked questions
Will renaming files break my website?
No. The plugin updates all references site-wide and creates 301 redirects from old URLs to new ones.
Can I revert to an old file name?
Yes. Each file maintains a short rename history so you can revert quickly.
Does it work with thumbnails?
Yes. All image sizes are renamed and redirected together with the main file.
Do redirects impact SEO?
301 redirects preserve SEO value and help search engines understand the change.
My Batch AI Rename stopped partway through a large batch (50-100+ files) – what happened?
On very large batches, an individual AI request can occasionally take longer than your hosting’s PHP max_execution_time (often 30s on shared hosting) or the AI provider’s own response time under load, causing that single step to time out. When this happens the affected file(s) are marked as failed instead of the whole batch silently freezing, and you can click Retry failed to resume just those files without restarting the entire batch. If you run large batches regularly, consider asking your host to raise max_execution_time to 60-120 seconds, and keep the browser tab active/in the foreground…
Changelog
First stable release of File Media Renamer for SEO. Includes safe renaming, automatic reference updates, redirects, and bulk features.
1.0.0
- Initial public release
1.0.1
- Fix redirect generation
1.2
- Add Claude (Anthropic) and Gemini (Google) as AI Rename providers, alongside OpenAI
- Fix a bug where thumbnail sizes sharing an identical physical file (common with page builders that register many crop/breakpoint sizes) could be left pointing at the old filename after a rename, breaking
srcset - Fix a bug where a batch or multi-thumbnail rename could silently skip updating the title, slug (post_name) and alt text for some files, because a background scheduling check ignored the specific file being processed
- Title, slug and alt text are now updated immediately when a file is renamed, instead of depending on WordPress cron
- Add a “Retry failed” button to Batch AI Rename so files that failed (rate limits, provider errors, timeouts) can be retried without restarting the whole batch
- Add clearer, provider-specific error messages for AI rename failures (e.g. when a model runs out of output tokens on internal reasoning, or is rate-limited)
- Increase the AI response token budget to avoid failures on models that use “thinking”/reasoning tokens (Gemini 2.5+/3.x, Claude Sonnet)
- Add a client-side timeout to Batch/AI rename requests so a hung request now fails gracefully instead of freezing the whole batch indefinitely
- Fix plugin JS/CSS assets not updating in the browser after a plugin update (automatic cache-busting)
- General sanitization and code cleanliness pass
- Add support for OpenAI’s reasoning models (o1/o3, GPT-5.x, GPT-5.6 Sol/Terra/Luna, GPT-6 Astra and future versions under these families) by sending a low
reasoningeffort automatically – keeps filename generation fast and cheap instead of using the model’s default (often “medium”) reasoning depth - Classic, non-reasoning OpenAI models (e.g. gpt-4o, gpt-4.1-mini) are unaffected – the request payload is unchanged for them
- Update the default OpenAI model for new installs to
gpt-5.6-luna; existing saved model settings are not changed - Add a clear, logged error message if a selected OpenAI model rejects the reasoning effort parameter, instead of a generic failure
