An EPS is the encapsulated PostScript file a print shop or an older design tool hands you. A
PNG is the picture every screen can show.
The file is print artwork, not a picture
An EPS describes a page as shapes, colours and curves, with a bounding box that says how
big it is. It was designed to be placed in a page layout or sent to a press, so double
clicking it on a desktop often does nothing at all: a browser, a photo viewer and a chat
window have no way to draw PostScript.
Every screen, form and document takes a PNG
A PNG goes into a slide, a website, a marketplace listing, a support ticket or an email,
and it appears in the preview of every file manager. That is the whole point of this
conversion: the artwork stays where it is on the server while a picture of it travels.
A preview you can actually look at
A folder of old print artwork, a logo a client sent years ago, a stack of test EPS files:
a PNG of each one makes the contents visible at a glance, with no editor to install, no
fonts to hunt down and no dialog complaining about a missing linked image.
What the PNG contains
The EPS already knows how large its artwork is; that rectangle becomes the picture.
Cropped to the EPS bounding box
An EPS has no sheet of paper around it, only a bounding box, and the render here is exactly
that box. The PNG is the size of the drawing — no A4 border and no white margin to trim
afterwards — so a logo that measures 200 × 100 points arrives as 200 × 100 points of
pixels, plus whatever the resolution adds.
The resolution decides the pixel size
Points are 1/72 of an inch, so 72 dpi turns one point into one pixel and a 200 × 100 pt
drawing into 200 × 100 px. At 150 dpi the same drawing is 417 × 208 px, and at 300 dpi it
is 833 × 417 px. Nothing is redrawn between the three: only the number of pixels changes.
The artwork sits on white
The page behind the drawing is white, not transparent, because an EPS describes ink on
paper and has no notion of a see-through background. If the drawing has to be a cut-out
with nothing behind it, take the vector version from
EPS to SVG instead and remove the background there.
One drawing, one file
A drawing EPS is a single page, so the answer is a single PNG named after the file you
uploaded — no archive to unpack. A multi-page PostScript print file is rendered from its
first page, which is nearly always the sheet that carries the artwork.
What 72, 150 and 300 dpi actually mean
Dots per inch decide how many pixels each inch of the drawing gets, and how heavy the PNG is.
72 dpi — posts and previews
One pixel per point: the drawing at the size it was measured in, which is fine for a
preview, a thumbnail, a forum post or a picture shown at its natural size on a web page.
It is the smallest PNG of the three, and small type can be hard to read if the image is
later enlarged.
150 dpi — standard
Twice the detail in each direction and the default here: sharp on any screen, comfortable
at 100%, and still a sensible download. Choose it for a document, a mock-up or a picture
that will be looked at rather than printed.
300 dpi — print
The resolution a print service asks for. Because PNG is lossless, a 300 dpi artwork is
genuinely heavy: use it for the one drawing that is going to paper, and keep the rest at
150 dpi.
Very large artwork is capped
A single page may not pass 40 megapixels. A plotter drawing or a poster-sized EPS requested
at 300 dpi is rendered at a lower resolution instead of exhausting the server, and the
answer carries a warning naming the resolution that was actually used.
Two honest limits of an EPS
PostScript is a program, and a program can depend on things that were never inside the file.
Fonts that were not embedded are substituted
An EPS rarely carries a typeface; it asks for one by name and expects the machine to have
it. When the font is missing, the letters are drawn in the closest match the server has, so
widths, spacing and the look of the text can shift. Converting the text to outlines in the
original application is the fix — every letter then travels as a shape.
A very complex file can hit the time limit
Each conversion has a wall-clock limit, so a file with tens of thousands of paths, a
gradient mesh or an embedded high-resolution bitmap can take longer than the server allows
and is stopped with a message instead of a half-drawn page. Simplifying the artwork, or
asking the source application for a PDF or an SVG export, is the quicker route.
How to convert an EPS to PNG
Three steps, no account and nothing to install.
Add the EPS
Drop the file on the box or click it to browse. One file per run, up to 25 MB. A file named
.eps or .ps is accepted even when the browser sends it without a
useful type, which is what happens with most PostScript downloads.
Pick the resolution
Keep 150 dpi unless you know better: 72 dpi for a preview, 300 dpi for a drawing that will
be printed. The PNG format is already chosen on this page, so there is nothing else to
decide.
Download the PNG
The file arrives with the name of your upload and a .png extension, already cropped to the
artwork, ready to be dropped into a slide, a page or a folder of previews.
Three tips before you convert
Small preparations that save a second attempt.
Check the bounding box in a text editor
An EPS is readable text. The first lines hold a %%BoundingBox entry with four
numbers — left, bottom, right, top — in points. Their difference is the size of the picture
you will get, so a suspicious value explains a PNG with a strange margin long before you
convert anything.
Outline the type in the source file
If you still have the application the file came from, convert the text to outlines before
exporting: Illustrator calls it Create Outlines, Inkscape Object to Path, CorelDRAW and
Affinity Convert to Curves. The PNG then matches the design exactly instead of borrowing a
substitute face.
Work out which direction you need
Going the other way is two clicks away: PNG to EPS traces a
picture back into vector shapes, and SVG to EPS writes a drawing
out as PostScript for a print shop. If the file you were handed is a PDF rather than an
EPS, PDF to PNG is the same conversion for that format.
Frequently asked questions
Is this EPS to PNG converter free?
Yes. There is no account, no payment, no watermark on the picture and no limit on how many files you convert. A short rate limit is the only restriction, so one visitor cannot occupy the server while everybody else waits.
Does the PNG keep the whole EPS or crop it?
It is cropped to the bounding box recorded in the EPS, so the picture is the size of the drawing with no sheet of paper around it. Points become pixels according to the resolution: a 200 × 100 pt logo is 200 × 100 px at 72 dpi, 417 × 208 px at 150 dpi and 833 × 417 px at 300 dpi.
Do I need Illustrator or another editor to convert an EPS?
No. The file is read on the server, so nothing has to be installed on your computer and no editor has to open it. Any EPS or PS file up to 25 MB works, including the old PostScript documents that design tools saved before PDF took over.
What are the limits of the conversion?
One file per run, up to 25 MB, and one page is rendered. Text is drawn with whatever fonts the server has, so an EPS that names a typeface it never embedded shows a substitute — outlining the text first avoids that. A file with an enormous number of paths can also reach the time limit and is stopped with a message instead of a half-drawn image.
What happens to my files?
Files are processed on our server and not stored. The EPS is rendered once and only the finished PNG is sent back to your browser, so the download is the only copy that leaves the conversion and no account is tied to it.
