SpeedSize AI‑Image Optimizer

April 29, 2026

We have been using SpeedSize for nearly 2 months, we are very happy with the results, better image quality, improved site speed. The implementation was very smooth, the SpeedSize team did a proof of concept to show what is achievable using the platform. The account management provided is great, they have suggested how we could further optimise the results and improve site speed. They are promptly available whenever we have questions. I would highly recommend to use this service.

We have just started with Speedsize and are seeing the results already. Site speed and quality of the images have increased. We would also mention the team who has helped us with onboarding making it a quick and easy process.

SpeedSize was easy to implement and didn’t interfere with our visual standards. We saw an immediate improvement in load times, particularly on mobile, while keeping textures and colors consistent. The site feels faster and smoother overall, without compromising image quality.

For a luxury brand, high-quality visuals are non-negotiable, but they usually kill load speeds. Speedsize has been a total game-changer for us. We have a huge number of high-res images and videos per product, and this app keeps everything looking premium while keeping the site incredibly light. A huge relief for us was the colour accuracy—unlike other compression services, Speedsize doesn't shift or dull colours, which was a major concern for us. The mobile experience is now flawless, with pages snapping into place instantly. The icing on the cake is that every team member has been incredibly responsive and accommodating to our needs. I couldn’t have asked for a better experience!

Great videos optimization and support. Videos are much more faster than before we implement it.

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.

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 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.

Very easy to use, very quick external implementation and great customer service.

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!

Has helped us with the new website photos / vids look more professional and more modern. Our photos are good, but now they just look much clearer / "crisp". I don't have to go on there and update anything which helps. it just does the job for us and helps save time most definitely.
