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.
