Free WordPress image format conversion

Convert JPG and PNG to WebP or AVIF in WordPress.

Rupanta Media Converter is a free WebP and AVIF converter for WordPress. Whether you need a WordPress JPG-to-WebP plugin, an AVIF image converter, automatic image conversion on upload or a bulk Media Library converter, it helps create modern-format copies of supported JPEG and PNG images directly on your server.

Convert JPG and JPEG to WebP in WordPress

Generate .webp versions of WordPress JPEG uploads and their supported image sizes while keeping the original JPG files available as a safe fallback.

Convert PNG to AVIF or WebP

Create modern AVIF or WebP copies of PNG images, including supported transparent images, without replacing or deleting the original PNG.

Bulk convert an existing WordPress Media Library

Run background batch conversion for previously uploaded images. Monitor converted, pending and failed attachments through progress indicators and per-file logs.

Automatically convert new WordPress image uploads

Enable WebP, AVIF or both so new JPEG and PNG files added to WordPress Media Library are processed using the server’s supported image encoder.

Deliver modern image formats with Elementor and Divi

Serve generated WebP and AVIF files for compatible WordPress attachment images and supported Elementor or Divi output while retaining an original-image fallback.

Use a free image converter without an external API

Keep image processing on your WordPress hosting server through GD or Imagick. There is no remote conversion service, subscription or plugin-imposed image quota.

  1. 1. Install and activate Rupanta Media Converter on WordPress.org.

Common questions

Clear answers before installation.

Are the original images replaced?

No. The plugin keeps the original JPEG and PNG files and creates separate WebP or AVIF versions alongside them.

Will conversion continue after I leave the page?

Yes. Existing media is processed in persistent background batches through WordPress cron, so the converter screen does not need to remain open.

Can I disable WebP or AVIF separately?

Yes. Each format can be enabled or disabled independently for both generation and frontend delivery.

What happens when one image fails?

The queue continues with later images. Failed attachments and their recorded reasons remain visible when an administrator returns.

Does the plugin use an external conversion service?

No. Conversion happens on your WordPress server through the available GD or Imagick encoder.

How do I convert JPG or PNG images to WebP in WordPress?

Install the free Rupanta Media Converter plugin from WordPress.org, open Media > Rupanta Media Converter, enable WebP and review your server encoder support. New JPG and PNG uploads can convert automatically, and the batch converter processes existing WordPress Media Library images.

Can I bulk convert my existing WordPress Media Library images to AVIF?

Yes. Enable AVIF and run the background batch converter to create AVIF versions of existing JPEG and PNG media attachments. Your WordPress hosting server needs GD or Imagick with AVIF encoding support.

Does the plugin automatically convert new WordPress image uploads?

Yes. With a supported image encoder and the selected format enabled, new JPEG and PNG uploads are converted automatically to WebP, AVIF or both. Existing uploads can be handled separately using batch conversion.

Is this a completely free WordPress WebP and AVIF converter with no quota?

Yes. The WordPress.org plugin includes its conversion features without a premium plan, license key, subscription, plugin-imposed conversion limit or cloud API. Processing capacity still depends on your own hosting resources.

Can Rupanta serve WebP or AVIF images in Elementor and Divi?

The plugin supports standard WordPress attachment markup and compatible Elementor and Divi-rendered image content. Enable frontend picture output, then check your pages to confirm that a particular theme or widget uses compatible image markup.

What if WordPress hosting supports WebP but not AVIF?

You can enable WebP conversion alone. The plugin detects the WebP and AVIF encoding capabilities of the available GD or Imagick library, so AVIF is optional.

Does converting images to WebP or AVIF improve WordPress page speed?

Modern formats can reduce image transfer sizes and support image optimisation, but actual results depend on the source image, quality settings, browser, hosting and page setup. Rupanta focuses on image format conversion and compatible delivery; it is not a full CDN or general-purpose image resizing service.
