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.

TGA Image

Raster & Vector Images

TGA (Targa) is a raster graphics format used in game development and video editing.

About TGA files

Strengths Comparison

PNG Strengths

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 Strengths

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.

Limitations

PNG Limitations

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 Limitations

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.
