Mobile app image optimization tips

Use these before you upload or share the page.

Use WebP format for Android assets — it delivers 25-35% smaller files than PNG at the same quality, which directly shrinks your APK.

For iOS, stick with PNG for icons and splash screens (Xcode optimizes PNGs further at build time), but use JPEG for photo-heavy in-app content.

Resize images to the exact display resolution your app needs before compressing — a 1080×1920 splash screen at 80% quality is often indistinguishable from the original at half the file size.
