All plans come equipped with: Full API Access, Web Interface PRO, WordPress Plugin, Magento Extension and Kraken.io Cloud Storage. Advanced and above include PRO Unlimited — Web Interface usage doesn't count against your quota.

Monthly Image Quota

The quota is the total amount of unprocessed image data you can optimize each month. For example, a 2 GB quota lets you upload and optimize up to 2 GB worth of source images before any overage charges apply. Quota resets at the start of every billing cycle.

On Micro and Basic plans, the quota is shared across both the API and the Web Interface — anything you process through either counts against the same monthly pool.

If you exceed your quota, additional usage is billed at the per-GB overage rate shown on the plan. You can upgrade at any time to get a larger allowance and a lower overage rate.

API Quota

The API quota is the total amount of unprocessed image data you can send to the Kraken.io API each month. It covers programmatic optimization requests from your own applications, WordPress plugin, Magento extension, and any other integrations using your API credentials.

On Advanced plans and above, API usage and Web Interface usage are tracked separately. Images you optimize via the Web Interface do not consume your API quota — Web Interface usage is unlimited on these plans.

Exceeding the API quota is billed at the per-GB overage rate shown on the plan. Quota resets at the start of every billing cycle.

Kraken.io Web Interface

The Web Interface is the online tool at kraken.io where you can optimize, compress, resize, and convert images directly in your browser — no code required. Just drag and drop your files (JPG, PNG, WebP, GIF, SVG, AVIF, HEIC, PDF) and download the optimized results in seconds.

It supports all the optimization modes available via the API — Lossy, Lossless, and Expert — as well as resizing strategies and format conversion. You can also upload ZIP archives containing multiple images and download the full processed archive when it is done.

PRO Unlimited (included on Advanced plans and above) means your Web Interface usage does not count against your API quota — process as many images via the Web Interface as you need without consuming your monthly allowance.

Kraken.io is trusted by individuals, startups and Fortune 500 companies.

If you need to cost-effectively scale your image processing to extremely high volumes, or have any additional or special requirements, we'll be happy to tailor a plan specifically for your business.
