JPG vs WBMP
Ein detaillierter Vergleich von JPEG Image und Wireless Bitmap — Dateigröße, Qualität, Kompatibilität und welches je nach Workflow zu wählen ist.
JPEG Image
Raster & Vector ImagesJPEG is the most widely used lossy image format on the web. It achieves small file sizes through adjustable compression, making it ideal for photographs and complex images where some quality loss is acceptable.
Über JPG-DateienWireless Bitmap
Raster & Vector ImagesWBMP (Wireless Bitmap) is a monochrome image format designed for early WAP-enabled mobile devices. It stores 1-bit black-and-white images with minimal overhead, optimized for the bandwidth constraints of early mobile networks.
Über WBMP-DateienVorteilsvergleich
JPG Vorteile
- Excellent compression ratio for photographs (10:1 or better without visible quality loss).
- Universal support — every camera, phone, OS, and browser reads JPEG natively.
- Adjustable quality setting balances file size against visual fidelity.
- Embeds EXIF metadata (camera model, GPS, exposure) automatically.
- Progressive rendering for graceful loading over slow networks.
WBMP Vorteile
- Tiny file size.
- Pre-smartphone mobile standard.
- Trivial to encode.
Einschränkungen
JPG Einschränkungen
- Lossy — every save degrades the image further (generation loss).
- No transparency channel (use PNG or WebP for that).
- Visible compression artifacts on text, sharp edges, and flat colors.
- Limited to 8 bits per channel — poor for HDR or print work.
- Baseline JPEG tops out at 65,535 × 65,535 pixels.
WBMP Einschränkungen
- Monochrome only.
- WAP era is dead.
- Zero modern use.
