Does iPhone have a built-in image compressor?
iOS does not include a dedicated image size compressor. The Photos app and Files app cannot reduce image file sizes. When sharing via Mail, iOS offers "Actual Size", "Large", "Medium", and "Small" options — but these give limited control over the output quality. CompressFiles gives you three precise compression levels and saves the file directly to your device.
Which compression level for iPhone photos?
- Low — Near-original quality. Best for professional photos or images you'll print.
- Medium — Recommended for most use cases: email, messaging, sharing. A typical iPhone photo (5–8 MB) compresses to under 500 KB.
- High — Maximum reduction. Best when you have a strict file size limit.
