SpeedSize AI‑Image Optimizer

We’re extremely happy with SpeedSize.

For us, image quality is critical - our products rely on sharp, detailed visuals - so we were very cautious about implementing any optimization tool. SpeedSize managed to significantly improve loading speed while keeping our images crisp and visually identical to the originals.

The difference in user experience is noticeable. Pages feel lighter, faster, and more responsive, especially on mobile. It’s one of those improvements that works quietly in the background but has a real impact.

On top of that, the team has been professional, supportive, and great to work with.

Highly recommended for any store that cares about both performance and visual excellence.

Speedsize has dramatically improved the quality and speed of my images and provided great optimization suggestions for my new site build.

We've had a good experience with Speedsize. Out store has a large number of high quality product images and we were experiencing issues with the site speed due to it. Implementing their tool did exactly what they advertised: greatly increased the speed of our website (namely LCP) to good levels, reducing the size of our images and videos without compromising quality at all.

We’d been stuck in Shopify’s “Moderate” speed range for a long time. SpeedSize made an immediate difference. Our LCP improved and we moved into the “Good” category, and the site feels noticeably faster. Their team has also been proactive about auditing our store and recommending other optimizations beyond their product, and those suggestions have been valuable.

SpeedSize have been great. Very smooth implementation and set-up. And very helpful since. The improvement to both resource load duration and Time to First Byte was immediate. Happy to recommend.

Great support—they respond quickly and are a pleasure to work with. They helped speed up our site by optimizing images and videos, and now we don’t have to worry about managing image performance ourselves. SpeedSize takes that completely off our plate.

SpeedSize has been great, a real innovation which has allowed us to leverage high quality content without impacting the speed of our site.

Kevin and the team made the integration process incredibly easy - a definite win for us in 2025!

We have had a great experience working with Speedsize. The insights are so helpful towards making our website more efficient and effective. Highly recommend.

SpeedSize has been really helpful for improving our site’s speed without losing image or video quality. The setup was simple, and their team has been responsive and supportive throughout the process. It’s made a noticeable difference on our Shopify store, and the service has been consistently good.

Great communication, innovative methods, and overall professionals with great support!
