Best Applications
PNG is best suited to applications that benefit from lossless raster image storage, transparency, sharp pixel-defined edges, or preservation of the encoded image information without lossy compression.
Transparent Raster Artwork
PNG is particularly well suited to raster artwork that requires a transparent background or partially transparent areas.
Common examples include:
- isolated artwork
- logos exported as raster images
- decorative graphics
- overlays
- product graphics
- digital illustrations
- production artwork without a visible rectangular background
PNG supports alpha transparency, allowing pixels to represent varying levels of opacity rather than being limited to fully visible or fully transparent states.
This makes PNG useful when artwork needs to appear over different:
- background colors
- product colors
- website backgrounds
- mockups
- materials or substrates
Graphics With Sharp Edges
PNG is well suited to raster graphics containing clearly defined edges, including:
- text
- line art
- icons
- diagrams
- interface elements
- simple illustrations
- graphics containing flat areas of color
Lossless compression avoids the block artifacts, ringing, and edge degradation that can occur when similar graphics are encoded using lossy compression.
Screenshots
PNG is commonly well suited to screenshots, particularly when the captured content contains:
- text
- menus
- interface elements
- diagrams
- icons
- sharp boundaries
- flat areas of color
These characteristics often compress effectively with PNG while retaining exact pixel information.
Raster Artwork Requiring Lossless Storage
PNG is appropriate when raster image information needs to be stored without intentional degradation caused by lossy compression.
Examples include:
- master raster exports
- production derivatives
- archival working exports
- intermediate image assets
- artwork exchanged between compatible applications
A PNG export should not necessarily replace the original editable source file. Native design files may contain layers, text, paths, effects, or other editable information that PNG does not preserve.
Production Artwork Requiring Transparency
PNG is particularly useful in compatible production workflows where the visible artwork must be separated from the background.
Examples may include:
- DTF artwork
- DTG artwork
- sublimation artwork
- UV-printing artwork
- print-and-cut artwork
- other compatible digital-printing workflows
Suitability depends on the production software and workflow requirements rather than on the .png extension alone.
Best-Use Decision Guide
| Requirement | PNG Suitability |
|---|---|
| Transparent raster background | Excellent |
| Partially transparent pixels | Excellent |
| Sharp raster graphics | Excellent |
| Screenshots/interface graphics | Excellent |
| Text within raster artwork | Strong |
| Line art stored as raster | Strong |
| Lossless raster storage | Excellent |
| Raster production artwork | Strong when workflow supports PNG |
| Large photographic image where small file size is critical | Often not optimal |
| Artwork requiring unlimited geometric scaling | Not appropriate as the source format |
| Editable vector paths | Not appropriate |
| Editable layered artwork | Not appropriate as a flattened export |
| CMYK-oriented prepress exchange | Generally not the preferred format |
| Machine instructions/toolpaths | Not appropriate |
