Image Optimizer: Compress JPG & PNG, Convert to WebP | Compressify

Images often account for a large part of a page’s total weight. Compressify is a straightforward WordPress image optimizer that reduces image file sizes and helps pages load faster without sending your media to an external compression service.

Compressify can automatically optimize new images as you upload them or bulk compress JPG, PNG, and WebP files already in your WordPress Media Library. Enable WebP conversion when you want to replace supported images with a modern, lightweight format.

All optimization takes place locally on your own server through the WordPress image editor. There is no API key to connect, no external account to create, and no monthly compression quota imposed by Compressify.

Optimize Images Without Changing Your Workflow

Turn on Automatic Compression and continue adding images through the familiar WordPress Media Library. Compressify processes supported uploads and the image sizes WordPress generates, helping you keep full-size images and thumbnails optimized from the start.

Prefer to stay in control? Leave automatic compression off and run the bulk image optimizer whenever it suits you.

Bulk Compress Your Existing Media Library

Already have an image-heavy website? You do not need to download, edit, and upload every file again. Bulk Compression finds supported images in your existing Media Library and processes them in manageable background batches.

A live progress indicator shows how much of the library has been processed. You can leave the dashboard while background processing continues and return later to review the results.

Convert JPG and PNG Images to WebP

WebP can provide smaller files than traditional JPG and PNG images while maintaining useful visual quality. Enable the WebP option and Compressify will convert supported Media Library images, update WordPress attachment metadata, process generated image sizes, and update matching media URLs stored in WordPress content and post metadata.

WebP conversion depends on WebP support in the image library configured on your server, such as Imagick or GD.

Choose the Right Compression Level

Every website has different priorities. Product photography may need more visual detail, while blog illustrations and decorative images can often tolerate stronger compression. Compressify provides two simple presets:

• Standard balances image quality with file-size reduction.
• High Compression aims for smaller files with more aggressive optimization.

If you switch to a stronger optimization option, previously processed images can be marked for re-compression so the new setting can be applied.

See Your Image Optimization Results

The Compressify dashboard gives you a clear overview of your Media Library, including:

• Total supported images.
• Number of optimized images.
• Original image size tracked during optimization.
• Total storage saved.
• Overall optimization progress.
• Images that were skipped because they were already efficient or could not be reduced.

Local Image Optimization, With No External API

Your images remain on your WordPress hosting environment during compression. Compressify uses the image-editing capabilities already available to WordPress, so there are no external uploads, API credentials, usage credits, or third-party compression queues.

Because processing happens on your server, compression speed and WebP availability depend on your hosting resources and its configured WordPress image editor.

Why Optimize Images?

Smaller image files can reduce page weight and transfer time. This is especially valuable for image-heavy blogs, portfolios, landing pages, and WooCommerce stores. Faster image delivery can create a smoother browsing experience for visitors on both desktop and mobile connections.

Compressify focuses on the essentials: compress images, convert supported files to WebP, and make it easy to optimize both new uploads and an existing Media Library.
