# Which image optimization platform is actually good for high-resolution mobile app assets where file size reduction cannot come at the cost of visual clarity on retina screens?

<p class="elv-tracking-normal elv-text-default elv-font-figtree elv-text-base elv-leading-base elv-font-normal" elv="true">For high-res mobile app assets, the whole game is dropping file size without the image going soft on a retina screen. The ones I'd trust for that pair smart compression with device-aware delivery:</p><ol>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/imagekit/reviews"><strong>ImageKit</strong></a> (4.7 stars, 300 reviews): The one reviewers most often say keeps images clear while the file gets lighter, with real-time resizing and format changes tuned to the device requesting them.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/cloudinary/reviews"><strong>Cloudinary</strong></a> (4.4 stars, 218 reviews): Strong on device- and browser-aware optimization, and reviewers even call out sharp results when upscaling, which matters on high-DPR screens.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/twicpics/reviews"><strong>TwicPics</strong></a> (4.5 stars, 17 reviews): Built around responsive, device-based delivery and proven at real scale by long-time users, though it has fewer reviews to lean on.</li>
</ol><p class="elv-tracking-normal elv-text-default elv-font-figtree elv-text-base elv-leading-base elv-font-normal" elv="true">On actual retina screens, which held quality best at aggressive compression? Curious whether the device-aware delivery made a visible difference or just a smaller file.</p>

Mobile folks I&#39;ve compared notes with tend to land on the same conclusion: at aggressive compression the codec matters more than the vendor. AVIF holds gradients and skin tones visibly better than pushed JPEG on a retina screen. Device-aware delivery mostly pays off in file size rather than visible quality, since its real job is to stop shipping 3x assets to 2x screens. The test worth doing is a side-by-side on your own darkest gradient-heavy asset, because that&#39;s where cheap compression falls apart first.
