Kraken.io Image Optimizer

Overview

Kraken.io is an image optimization and compression service that reduces the file size of JPG, PNG, WebP, GIF, SVG, AVIF, HEIC and PDF images without sacrificing visual quality. It processes images on its own servers, freeing users from using local computing resources.

Designers, developers, WordPress and Magento users, and enthusiasts use Kraken.io to accelerate websites, save bandwidth, and reduce storage costs. Unlike manual compression tools or basic plugins, Kraken.io offers a web interface, a full API, and official CMS plugins under one account.

Key Benefits

• Reduces image file sizes dramatically while preserving visual quality that stands up to close inspection.
• Offloads all processing to Kraken.io's servers so users do not consume their own computing resources.
• Supports 8 image formats: JPG, PNG, WebP, GIF, SVG, AVIF, HEIC, and PDF.
• Includes resizing features to generate optimized image sets for multiple target devices including mobile and tablets.
• Trusted by companies including Microsoft, with Anton Molleda reporting easier integration and reduced bandwidth usage.

How It Works

You upload your images through the Kraken.io Web Interface, via the REST API, or through the official WordPress or Magento plugins. Kraken.io's servers process each image through its optimization pipeline, compressing JPG, PNG, WebP, GIF, SVG, AVIF, HEIC and PDF files without degrading visual quality. You download the optimized results or store them directly in Kraken.io Cloud Storage.

Use Cases

• Web designers — compress final page layouts and assets before publishing to reduce page weight.
• Software developers — integrate the Kraken.io API into applications to automate image optimization and resizing in build pipelines.
• WordPress site owners — use the official plugin to compress images directly from the WordPress admin dashboard.
• Magento store operators — install the Magento extension to optimize product images and speed up the online store.
• Mobile and tablet content teams — generate optimized image sets for multiple target devices using Kraken.io's resizing features.
