Squeeze

Description

This plugin uses Squoosh.app compression scripts, allowing you to compress images directly from your WordPress media library or during the image upload process. All the compressions are handled directly inside your browser. That means there’s no third party service for compression images. Thus, you can be sure with the privacy of your images.
Important notice: this is NOT the official Squoosh.app plugin. It only uses squoosh.app compression scripts.

Features

  • Image Compression: Automatically compresses images in your WordPress media library using Squoosh.app advanced compression algorithms.
  • Upload Optimization: Compresses images on-the-fly during the upload process, ensuring optimized images are added to your media library.
  • Bulk Compression: Allows you to compress multiple images at once.
  • Selective Compression: Choose which images to compress based on your preferences and requirements.
  • Custom Compression Settings: Adjust compression parameters such as quality, resizing, and format options to suit your specific needs.
  • Restore Option: Provides a restore option to use backup file to restore compressed image to the original image.
  • Custom Path Compression: Select a folder on your site and compress all the images within that folder.

FAQ

What does the speed of image compression depend on?

Because the compression process happens directly into your browser – it depends on your device’s performance.

Image compression process seems to be stuck. The browser doesn’t respond.

It may happen if you are trying to compress a PNG image with a high resolution. In that case, you should wait a while, until the image finishes its compression or a “Request timed out.” error message occurs.

How to fix a “Request timed out” error

Go to the plugin’s setting page (Media -> Squeeze Settings).
At the “Basic Settings” tab increase the value of the field “Compression timeout (in seconds)”. By default it equals 60 seconds, try to make it bigger. If the error still persists, that means the script cannot process your image.

How does the plugin work?

The plugin uses Squoosh.app’s compression algorithms and provides you with the ability to compress images in your WordPress media library or during the image upload process.

How are the images processed? Are they sent to an external server?

This plugin uses Squoosh.app compression scripts. The images compressed directly in your browser – means no external server used. Squoosh does all the work locally. So you should not worry about privacy.

Why should I use image compression on my website?

Image compression helps improve your website’s performance by reducing the file size of images without significantly impacting their quality. Smaller image files load faster, resulting in faster page load times and a better user experience. Additionally, compressed images consume less bandwidth, which can be beneficial for websites with limited hosting resources or mobile users with limited data plans.

Which image formats does the Squeeze plugin work with?

Currently, the Squeeze plugin supports JPG, PNG, WEBP and AVIF image formats.

Can I compress multiple images at once?

Yes, the plugin provides a bulk compression feature. This saves time and effort compared to compressing images individually.

Can I compress images NOT from the Media Library, but from a custom folder?

Yes, you can compress images from any folder within your WordPress installation.

Can I customize the compression settings?

Yes, the plugin allows you to customize various compression settings according to your preferences. It supports the same options as Squoosh.app provides.

How can I test compression settings before uploading my images to the media library?

You can test different options directly on Squoosh.app. For JPG images select MozJPEG encoder, for PNG images choose OxiPNG.

I’ve been waiting for a plugin that can leverage Squoosh compression for years! I’m impressed!If I had one feature request it would be auto resizing to a specific set of dimensions like in Squoosh 🙂
