# 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>

&lt;p&gt;&lt;span style=&quot;color: rgb(0, 0, 0);&quot;&gt;Even with the smaller review count, TwicPics being proven at real scale by long-time users is worth weighing. A smaller sample of people who&#39;ve actually stuck with it through scale tells me something a bigger pile of early-impression reviews doesn&#39;t.&lt;/span&gt;&lt;/p&gt;

### Comment 2

&lt;p&gt;ImageKit would be the one I’d test first for aggressive compression without visible softness. Device-aware delivery matters most when it serves the right dimensions and format for high-DPR screens, rather than just shrinking the same asset more aggressively.&lt;/p&gt;

### Comment 3

&lt;p&gt;The codec point is useful because vendor comparisons can hide how much the source format affects the result. I’d also test screenshots and UI assets separately from photography since text, gradients, and fine edges expose compression differently. Has anyone compared ImageKit and Cloudinary at the same AVIF quality settings rather than their respective defaults?&lt;/p&gt;

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.
