A standard 12 MP photo saved as JPEG at 80% quality compresses from 34 MB uncompressed to about 3.4 MB, a 10:1 reduction with no visible quality loss.

A professional shoot of 500 RAW images from a 24 MP camera at 48-bit depth requires about 47 GB of storage.

A 4K screenshot saved as WebP at 80% quality is about 1.8 MB, roughly 25% smaller than the equivalent JPEG.
Uncompressed file size equals width times height times bytes per pixel. For a 24-bit image (standard RGB), each pixel uses 3 bytes. So a 4000×3000 image = 12 million pixels × 3 bytes = 36 MB uncompressed. Compression reduces this dramatically: JPEG at 80% quality compresses about 10:1, producing a 3.6 MB file.
| Resolution | Megapixels | Uncompressed (24-bit) | JPEG 80% |
|---|---|---|---|
| 1920×1080 | 2.1 MP | 6.2 MB | 0.6 MB |
| 4000×3000 | 12 MP | 36 MB | 3.6 MB |
| 6000×4000 | 24 MP | 72 MB | 7.2 MB |
AVIF produces the smallest files, roughly 50% smaller than JPEG at equivalent visual quality. WebP is second, about 25–35% smaller than JPEG. For photos, use AVIF or WebP for web delivery and JPEG for maximum compatibility. PNG is best for screenshots and graphics with sharp edges.
| Format | Type | 12 MP Photo | Best For |
|---|---|---|---|
| AVIF | Lossy/Lossless | ~1.7 MB | Web delivery |
| WebP | Lossy/Lossless | ~2.8 MB | Web, good compat |
| JPEG | Lossy | ~3.6 MB | Universal sharing |
| PNG | Lossless | ~14.4 MB | Screenshots, alpha |
JPEG quality 80% provides the best balance of file size and visual quality for most photos. At 80%, the file is roughly 10x smaller than uncompressed with virtually no visible artifacts. Quality 95–100% looks identical but produces files 3–4x larger. Below 60%, compression artifacts become noticeable.
RAW files are typically 1.5x the sensor's megapixel count in megabytes. A 24 MP camera produces ~36 MB RAW files. A 45 MP camera produces ~67–85 MB RAW files. RAW files contain unprocessed sensor data at 12–14 bit depth with minimal compression, making them 5–10x larger than JPEG but essential for professional editing.
Storage needs vary by format and resolution. For a 24 MP camera: 1,000 JPEG photos at 80% quality need about 7.2 GB. The same 1,000 photos in RAW need about 72 GB. In WebP, you would need roughly 5.4 GB. Always plan for 20–30% extra storage as a buffer.
