FAQ
Frequently asked questions about the free GetWebP WordPress plugin, local browser-side optimization, credits, delivery, and compatibility.
Frequently Asked Questions
Will the plugin modify or delete my original images?#
No. GetWebP writes generated WebP and optional AVIF files next to the original upload. Original JPEG and PNG files stay in place.
Uninstalling the plugin leaves original uploads untouched.
Does it work with WooCommerce product images?#
Yes for product images stored as standard WordPress Media Library attachments. They can be scanned and optimized manually, and generated WebP files use the same standard WordPress delivery paths.
Does GetWebP require an account?#
Yes. The current WordPress admin UI requires a free GetWebP account connection before scanning, previewing quality, or saving optimized files. The free plugin does not require a license key.
The account connection is used for site authorization, credits, and job status. It does not upload image files to GetWebP.
Will it work on shared hosting like SiteGround or Bluehost?#
Usually, yes. Encoding runs in the administrator's browser, so the site does not need ImageMagick, GD, Imagick, or another server-side image library.
The site still needs PHP 7.4+, writable uploads, same-site admin requests, and a current desktop browser for the admin screen.
Can I download the free plugin before the WordPress.org listing is approved?#
Not as a public download. GetWebP for WordPress is under WordPress.org review, and the public installation source will be the WordPress.org plugin directory once the listing is approved.
Private ZIP builds are used only for internal testing. Avoid third-party mirrors.
What happens when free credits run out?#
The free account includes 100 monthly optimization credits and up to 20 images per browser batch.
When credits are exhausted:
- new optimization runs cannot start until reset or upgrade
- generated files already saved stay in place
- standard WebP delivery continues for generated WebP files
- original uploads are not changed or deleted
Quality preview does not consume credits because it writes no files, but the preview action is available only when the site is connected and service status allows optimization to continue.
Does GetWebP support WordPress Multisite?#
Yes. The free plugin is network-compatible. Settings, history, stats, service connection state, and credit status are shown per site. Credit availability follows the connected GetWebP account and plan terms.
If I uninstall the plugin, will my site break?#
No. Originals stay in place, so WordPress can continue serving original JPEG and PNG files.
Plugin options and GetWebP attachment metadata are removed on uninstall. Generated files may remain in uploads unless you delete optimized copies before uninstalling.
Can I undo a batch or delete generated copies?#
Yes. Use run history to undo a stored optimization run, or use GetWebP -> Settings -> Maintenance -> Delete optimized copies to remove all tracked generated files.
Original uploads remain in place. See Undo & Cleanup.
Is it compatible with caching plugins like WP Rocket or W3 Total Cache?#
The free plugin uses standard WordPress delivery paths and does not write server rewrite rules. After a large optimization run, clear your page cache and CDN cache so cached HTML and asset references refresh.
Can I use it with a CDN or WP Offload Media?#
GetWebP detects common offload setups and keeps free delivery conservative. Generated files are written to local uploads first. CDN or object-storage delivery depends on your offload plugin's sync behavior.
How fast is conversion?#
Speed depends on the administrator's browser, source image dimensions, enabled formats, and machine resources. Keep the GetWebP tab open while a batch runs. For very large images, run smaller batches.
Does GetWebP send images to an external optimization service?#
No. Optimization runs in the administrator's browser and generated files are saved back through same-site WordPress admin requests. The plugin does not send original image files, decoded pixels, or generated WebP/AVIF files to GetWebP.
Service calls may send bounded metadata for account connection, credits, and job authorization, such as site token state, local attachment identifiers, source MIME type, dimensions, byte size, requested outputs, preset, and job status. See Service Account & Credits.
