PNG Image

Raster & Vector Images

PNG is a lossless image format that supports transparency. It is ideal for graphics, logos, screenshots, and any image where preserving exact pixel data is important.

Vorteilsvergleich

PNG Vorteile

Lossless compression — every save preserves the original pixels perfectly.
Full 8-bit alpha channel for smooth transparency.
Excellent for text, UI screenshots, logos, and line art.
Royalty-free and an ISO standard (ISO/IEC 15948).
Supports 16-bit color depth for high-fidelity work.

TGA Vorteile

Extremely simple — trivially easy to read and write.
Lossless with optional RLE compression.
Supports 8, 16, 24, and 32-bit color with alpha channel.
Universal in legacy game development and 3D rendering pipelines.

Einschränkungen

PNG Einschränkungen

Much larger than JPEG for photographs (no perceptual compression).
No native animation in most software (APNG support is inconsistent).
No CMYK support — web and screen only, not print.
Metadata capabilities are less rich than JPEG's EXIF.

TGA Einschränkungen

No metadata, no color profile, no gamma correction.
Aging — PNG and EXR cover its use cases with better compression.
Bottom-up pixel order trips up newcomer parsers.
Not a web format — browsers don't display TGA natively.
