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.

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!

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 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.
