TIO – The Image Optimizer – Smart Image Compression & Optimization, Built for the Web

Description

Make your website faster than ever with TIO’s smart optimization.

Upload your images like you’ve always done before, and we’ll handle the rest. The Image Optimizer compresses your image and converts it to a modern file format. The result is the lightest image possible, without losing the quality.

Why choose our plugin?

The Image Optimizer uses smart optimization parameters tuned specifically for website images. It’s designed to be a simple companion that gives you the perfect image every time. We decide on the perfect balance of size and quality for your uploaded image. TIO automatically converts your new uploads to the best format (including modern formats like WebP and AVIF), applies lossless conversion or uses lossy compression settings that don’t affect the quality.

It’s perfect for small marketing teams who don’t have the time and know-how to optimise images manually and busy agencies who can’t afford the time to do it manually at scale.

We developed TIO to solve our own frustration with image optimizers. As a result, we were able to achieve results up to 35% file size reduction compared to other compressors. Going the extra mile helps ticking off the Google PageSpeed insights image checks, especially those for next-gen image formats.

How it works?

You upload your images as you normally do — one by one or in bulk, either way is fine. You can do it via the WordPress media library and by uploading directly into your pages.

We categorise what’s in the image to apply the right optimization settings. We use suitable compression and file format conversion, as well as remove unnecessary metadata.

As an example, screenshot compression makes sure to not sacrifice text sharpness, while plain illustrations with low colour depth use more aggressive compression since it won’t affect the quality nearly as much.

We optimise the source file, so WordPress thumbnails come pre-optimised as well.

Supported file formats

The only excluded file format is GIF. We support all other file formats that WordPress allows, including HEIC.

Try it for free

TIO allows you to generate one license key with 50 free image credits per website. That’s enough to test a few core pages and measure the impact.

1. Get a free license key at theimageoptimizer.com/key
2. Paste the key in Settings > TIO Image Optimizer
3. Upload images as usual — they are compressed automatically

Credit restoration for peace of mind

Uploaded an image by mistake or we didn’t optimise it to your liking? You can reclaim the credit straight from the WordPress Media Library, subject to our Terms.

And if we notice that your image was already optimal, we won’t charge a credit in the first place — nothing to reclaim there!

External Service Disclosure

This plugin relies on The Image Optimizer API, a third-party service hosted at api.theimageoptimizer.com, to compress images. When you upload an image with auto-compress enabled, the plugin sends the image file and your site URL to this API. The API returns a compressed version of the image, which replaces the original in your media library.

No data is collected or stored beyond what is needed to process the compression request and manage your credit balance.
