Quality Preview

Preview GetWebP compression settings before writing generated WebP or AVIF files to your WordPress uploads folder.

Quality Preview

The free WordPress plugin does not automatically optimize new uploads. It is built for manual, reviewable optimization: choose settings, preview a sample, then run the batch you want to write.

No GetWebP account, license key, credits, or external service connection is required to preview, scan, or optimize.

When to Use Preview#

Use preview before a large Media Library run, after changing presets, or before enabling AVIF output. It gives you a quick visual check before generated files are saved to uploads.

Open the Preview#

  1. Go to GetWebP in WordPress admin.
  2. Open Settings.
  3. Choose Balanced, Aggressive, or Ultra.
  4. Set an optional max width for very large images.
  5. Click Preview quality.

What Preview Does#

GetWebP samples up to five eligible unoptimized JPEG, PNG, or BMP Media Library images and processes them in the administrator's browser. No generated files are saved during preview.

The preview helps you compare:

  • visual quality
  • estimated file-size reduction
  • resize impact when max width is enabled
  • WebP and optional AVIF output choices

Preview Does Not Write Files#

Preview samples up to five eligible images in one bounded pass and does not write generated files or mutate attachment metadata. It is available without an account and is not controlled by a usage quota or external service status.

New Uploads#

New uploads are not optimized automatically in the free plugin. To optimize newly uploaded images, open GetWebP, scan the Media Library, and run a manual batch or single-image action.
