ryan is designing an app that needs to quickly send low quality photos between users. most smartphones take much higher quality photos than ryan needs for his app. which answer best describes the type of compression ryan should choose and why?
Ryan should choose lossy compression because it dramatically reduces file sizes for faster transmission, which is ideal since his app only needs low- quality photos from high-res smartphone originals.
Why Lossy Fits Best
Lossy compression discards non-essential data—like subtle color gradients humans barely notice—shrinking files by 80-90% without ruining usability for quick previews.
Formats like JPEG or WebP excel here, powering apps from Instagram to WhatsApp for speedy sharing over spotty networks.
In contrast, lossless keeps every pixel perfect but barely cuts size (often <50%), slowing Ryan's app unnecessarily.
Compression Breakdown
Type| How It Works| File Size Reduction| Best For Ryan's App?| Example Formats
3
---|---|---|---|---
Lossy| Removes "unimportant" data permanently| High (e.g., 10MB → 1MB)|
Yes – Speed + low quality OK| JPEG, WebP, AVIF
Lossless| Reversible; no data lost| Low-moderate| No – Too bulky for
quick sends| PNG, GIF
Real-World App Angle
Imagine Ryan's users snapping 12MP pics (huge files) but only needing thumbnail previews—lossy hits 100KB instantly, dodging data costs and lag.
Quiz sources confirm: "Lossy compression since it typically results in smaller data sizes."
TL;DR: Go lossy for speed; it's the pro move for low-quality, high-speed photo apps.
