How image compression works
Lossy formats (JPG, WebP) discard detail the eye barely notices; the quality slider controls how much. WebP (by Google) supports lossy and lossless compression plus transparency and is typically 25–35% smaller than JPG at similar quality. All modern browsers support it.
Private by design
Your images are processed with your browser’s built-in canvas engine and never uploaded to a server — safe for personal photos, ID scans and client work. It also means there are no file limits or queues: speed depends only on your device.

| 80% | ≈ 40–50% | None for most photos |
| 70% | ≈ 30–40% | Slight on close zoom |
| 50% | ≈ 20–25% | Noticeable in gradients |
