PNG to EPS Converter

EPS (Encapsulated PostScript) is still requested by print shops, sign makers, stock agencies and older layout software. A PNG can become an EPS in two very different ways, and this converter offers both: a raster EPS that wraps the exact pixels in PostScript, and a vector EPS whose shapes are traced from the image, so they scale cleanly and keep transparency. Everything runs in your browser; the image is not uploaded.

How to use this tool

1. Choose one or more PNG images.
2. Pick Raster for photos and screenshots, or Vector for logos, icons and line art.
3. Set the print resolution (it fixes the physical size) and, for vectors, the number of colours and detail.
4. Download the .eps files and place them in Illustrator, InDesign, CorelDRAW or your print workflow.

Formula

size in points = pixels × 72 ÷ DPI; %%BoundingBox = 0 0 ⌈width pt⌉ ⌈height pt⌉. Raster: a PostScript image dictionary (8 bits per channel, DeviceRGB) reading Flate-compressed (level 3) or plain (level 2) data through an ASCII85 filter. Vector: one even-odd filled path per colour, built from moveto, lineto, curveto and closepath.

The raster data follows the program as ASCII85 text ending in "~>", and the filter is flushed afterwards so the file reads cleanly. Vector tracing uses the same method as the PNG to SVG converter: colour reduction by median cut and k-means, marching-squares outlines, Ramer–Douglas–Peucker simplification and smooth Bézier curves.

Example

A 1200 × 600 px logo at 300 DPI becomes an EPS of 288 × 144 pt (1200 × 72 ÷ 300 = 288), which prints 4 × 2 inches. As a raster EPS it shows exactly the PNG pixels on a white background; as a vector EPS with 4 colours it holds four filled paths that stay sharp at any size, with the empty areas left transparent.
