EPS vs PNG
A detailed comparison of Encapsulated PostScript and PNG Image — file size, quality, compatibility, and which format to choose for your workflow.
When choosing between EPS and PNG for your images, the right pick depends on whether you need transparency, smaller file sizes, or maximum quality. This guide compares both formats side by side.
Encapsulated PostScript
Raster & Vector ImagesEPS is a PostScript-based vector image format historically used in print and publishing. While largely superseded by PDF and SVG, it remains common in legacy print workflows and stock illustration libraries.
About EPS filesPNG Image
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.
About PNG filesStrengths Comparison
EPS Strengths
- Vector-based — infinite resolution with no rasterization artifacts.
- Preserves exact CMYK colors, spot inks, and print-ready metadata.
- Universally accepted by professional prepress and sign-making workflows.
- Self-contained — fonts and images can be embedded inside the file.
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.
Limitations
EPS Limitations
- Legacy format — Illustrator 2020+ deprecated EPS import for security reasons.
- No built-in support for transparency — a longstanding pain point for designers.
- Web browsers do not render EPS; previews are often a low-res TIFF thumbnail.
- PostScript parsing is slow and memory-hungry compared to modern vector formats.
- Newer work is better handed off as PDF or SVG.
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.

Use SVG for web and digital graphics since it is natively supported by browsers and is XML-editable. Use EPS for professional print workflows and legacy design pipelines where PostScript compatibility is required.
