Compress images for App Store submission
Xcode lets you drag in any screenshot, but oversized store assets slow your upload and take up your developer dashboard allowance. Skwish compresses your App Store screenshots and icons locally in the browser so the build stays lean and the listing loads fast.

App Store asset optimization tips
Use these before you upload or share the page.
Apple's screenshots need 6.5-inch, 5.5-inch, 6.1-inch, and iPad sizes — resize each to the exact pixel size before compressing to avoid rejection.
Prefer JPEG at 80% quality for photo-like screenshots; keep PNG for screenshots with small text or sharp UI so it stays crisp.
Aim to keep individual screenshots well under 1MB — store previews that load fast convert better.
