Raster & Vector ImagesPNG 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.
Over PNG-bestandenVergelijking van sterke punten
EXR Sterke punten
- Genuine high-dynamic-range storage (32-bit float per channel).
- Multi-channel layers native — store an entire render pass in one file.
- Industry standard across every major VFX and animation studio.
- Deep samples enable modern compositing workflows.
- Open-source reference implementation with mature tooling.
PNG Sterke punten
- 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.
Beperkingen
EXR Beperkingen
- Enormous file sizes.
- Not a web format — browsers don't display EXR.
- Decoding is CPU-intensive.
- Consumer apps rarely need HDR at this precision.
PNG Beperkingen
- 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.
