Title: ArshadStudio Bulk Image Converter to WebP Author: Arshad Shah Published: June 14, 2026 Last modified: June 14, 2026 --- Search plugins ![](https://s.w.org/plugins/geopattern-icon/arshadstudio-bulk-image-converter-webp. svg) # ArshadStudio Bulk Image Converter to WebP By [Arshad Shah](https://profiles.wordpress.org/arshadwpdev/) [Download](https://downloads.wordpress.org/plugin/arshadstudio-bulk-image-converter-webp.1.0.0.zip) * [Details](https://wordpress.org/plugins/arshadstudio-bulk-image-converter-webp/#description) * [Reviews](https://wordpress.org/plugins/arshadstudio-bulk-image-converter-webp/#reviews) * [Installation](https://wordpress.org/plugins/arshadstudio-bulk-image-converter-webp/#installation) * [Development](https://wordpress.org/plugins/arshadstudio-bulk-image-converter-webp/#developers) [Support](https://wordpress.org/support/plugin/arshadstudio-bulk-image-converter-webp/) ## Description ArshadStudio Bulk Image Converter to WebP adds a dashboard screen that walks you through three steps: 1. **Choose a conversion type** — JPG to WebP or PNG to WebP. 2. **Preview the matching images** — the plugin lists every image in your Media Library that matches the selected format, with a thumbnail, filename, and file size. 3. **Convert** — optionally tick “Delete the original after conversion,” then start. A live progress bar shows status, and each thumbnail is marked with the percentage saved or a failure flag. The plugin performs genuine pixel-level re-encoding using the Imagick extension ( preferred) or the GD extension — it never simply renames a file extension. Every output file is verified against the WebP binary signature before it is accepted, so you can trust that the result is a real WebP image. Conversion runs one image per request over AJAX, which avoids PHP execution-time limits on large libraries. When “delete originals” is enabled, the Media Library attachment is repointed to the new WebP file and its metadata is regenerated, keeping the library consistent. ## Screenshots [⌊Step 1 — choose the conversion type and quality.⌉⌊Step 1 — choose the conversion type and quality.⌉[ Step 1 — choose the conversion type and quality.

Upload the `arshadstudio-bulk-image-converter-webp` folder to the `/wp-content/ plugins/` directory, or install the plugin through the WordPress Plugins screen directly. 2. Activate the plugin through the “Plugins” screen in WordPress. 3. Open the “WebP Converter” menu item in your dashboard. ## FAQ ### Does this actually re-encode images, or just rename them? It performs real conversion. The source pixels are decoded and re-encoded with the WebP codec, then the output is validated against the RIFF/WEBP binary signature. Files that are not genuine WebP images are reported as failed. ### Will my original images be deleted? Only if you explicitly check the “Delete the original” option and confirm the warning. By default, originals are kept and a new `.webp` file is created alongside them. ### What does my server need? PHP 7.2 or newer, plus either the Imagick extension (with WebP support) or the GD extension with the `imagewebp()` function. The plugin detects this automatically and shows a notice if neither is available. ### Why are converted images not being served to visitors automatically? This plugin focuses on conversion. Serving WebP to supported browsers while keeping a fallback is handled separately, for example via server rewrite rules. A future version may add an optional serving layer. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “ArshadStudio Bulk Image Converter to WebP” is open source software.
