It supports WordPress Core media upload workflows, including the Media Library and Block Editor. Choose between two normalization modes: **Idun normalization**, the default option for consistent lowercase ASCII filenames, and **WordPress standard**, which preserves filenames according to WordPress settings. **Simple. Lightweight. Effective.** * Review and edit filenames individually, or use `{original-name}` in a filename pattern to rename files automatically without individual confirmation. * Build filenames with `{upload-name}`, `{original-name}`, `{post-name}`, `{custom- string}`, `{date}` (YYYYMMDD), `{year}`, `{month}`, `{day}`, and `{sep}` (the selected hyphen or underscore separator). * Choose Idun normalization for lowercase ASCII filenames or WordPress standard normalization to leave final filename sanitization to WordPress. * Enable renaming for all accepted file types or selected file groups. * Review a live pattern example and reset the editable filename when needed. * Upload several files while retaining individual filename preparation. Clear, descriptive filenames can also support SEO by helping search engines understand the content of uploaded files, particularly images. Idun Simple Upload Renamer makes it easier to apply consistent naming conventions, while leaving the choice of filenames and naming patterns to the user. WordPress continues to determine permitted file types, process uploads, sanitize filenames, resolve filename collisions, and store attachments. For block-editor uploads, Idun uses the WordPress REST upload workflow. It does not rename existing media, change existing URLs, or replace WordPress upload handlers. Uploaders that do not use the supported WordPress Core interfaces are not intercepted. ## Screenshots [⌊Configure filename patterns and review a live example in Settings.⌉⌊Configure filename patterns and review a live example in Settings.⌉[ Configure filename patterns and review a live example in Settings.

Simply include `{original-name}` in your filename pattern, optionally combining it with other placeholders such as `{sep}`, `{date}`, or `{custom-string}`. For example, `{date}{sep}{original-name}` automatically applies your naming pattern without requiring individual confirmation. ### What is the difference between Idun normalization and WordPress standard? **Idun normalization** produces consistent lowercase ASCII filenames, using the selected separator and converting supported accented characters. **WordPress standard** follows WordPress filename sanitization rules, preserving filenames according to WordPress settings. You can switch between the two modes at any time in the plugin settings. ### Does the plugin support filenames in Chinese, Hindi, Arabic, Cyrillic, and other non-Latin scripts? Yes. The plugin offers two normalization modes: * **Idun normalization (default):** Produces consistent lowercase ASCII filenames. * **WordPress standard:** Preserves filenames according to WordPress settings, including Chinese, Hindi, Arabic, Cyrillic, and other non-Latin scripts where supported. Simply select your preferred mode in the plugin settings. ### Does the plugin rename existing files? No. The naming rules are applied before supported new uploads, not to media already saved in the library. ### Does Idun override WordPress file security or filename uniqueness? No. WordPress remains responsible for upload permissions, file-type validation, filename sanitization, and uniqueness. ### Does it work in the block editor? Yes. Supported block-editor media uploads are handled through the WordPress Core REST media endpoint. ### Does it work with third-party upload plugins? The plugin features a lightweight compatibility check that identifies registered callbacks on selected hooks and highlights potential interactions with other plugins. The plugin is designed to work alongside other components without altering their hooks or execution order, allowing them to continue processing files through the normal WordPress upload flow. ### What happens when I cancel? The selected file is not uploaded by Idun’s pending operation. Other files in a batch can continue according to their own choices. ### Can I return to the original suggested name? Yes. Use Reset in the filename dialog. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “Idun Simple Upload Renamer” is open source software.
