PNG to EPS Converter

PNG to EPS Converter

EPS — Encapsulated PostScript — is the file a print shop, a page-layout app or an older RIP asks for when it will not accept a bare image. This converter produces one by embedding your PNG's pixels inside a PostScript program with a bounding box the layout software can position. It is a container change, not a redraw: nothing here traces your artwork into curves, and the output scales exactly as well or as badly as the PNG did. That trade-off, and the two things it does to your image on the way through, are laid out below.

What This Converter Actually Does

The PNG is decoded, its first frame is selected, and ImageMagick writes it into an EPS at a density of 72 dots per inch so that one pixel becomes exactly one PostScript point. That makes the declared bounding box identical to the pixel dimensions — a 1920 × 1080 PNG comes out with a bounding box of 1920 by 1080 points — which is what lets InDesign, QuarkXPress or a RIP place the graphic at a predictable size. Existing metadata is stripped on the way through.

Two consequences follow from that, and neither is obvious from the file extension:

• The result is still a bitmap. Enlarging the placed EPS past the PNG's native pixel count softens it exactly as enlarging the PNG would. "Convert to EPS" and "make my logo scalable" are different operations; only the second involves tracing.
• The pixel data is written uncompressed. The file the converter emits declares PostScript LanguageLevel 1 and %%DocumentData: Clean7Bit, which means the picture is stored as plain ASCII hexadecimal — six characters per pixel for a true-colour image, with no compression filter available at that language level. EPS files from this converter are therefore very large.

The EPS This Converter Writes

Because the encoding is fixed, the file size is essentially a function of pixel count rather than of image content. In our testing three very different 1920 × 1080 sources — a photograph, a logo on a transparent background, and a plain graphic with alpha — each produced an EPS of about 12.6 MB, all within a few bytes of 12,606,815, while the source PNGs ranged from 19 KB to 1.5 MB. Dropping the resolution to 50% produced a 960 × 540 bounding box and a 3,155,974-byte file: a quarter of the area, a quarter of the bytes.

PNG vs EPS

How to Convert PNG to EPS

1. Upload Your PNG File: Drag your PNG onto the page or click "+ Add Files". Several files can be queued and each becomes its own .eps; .apng is accepted, and only its first frame is used.
2. Leave "Keep original" or Set a Percentage: The "Image resolution" group is the only control on this page. "Keep original" is preselected and embeds the image at its native pixel size; switch to "Resolution Percentage" and use the "By Percentage" slider to shrink it before it is embedded.
3. Decide the Percentage With the File Size in Mind: Because the pixel data is uncompressed, halving the percentage cuts the output to roughly a quarter. This is the only lever that meaningfully changes the size of the EPS — there is no quality slider, no compression choice and no DPI setting here.
4. Convert and Download: Click "Convert" and save the .eps. No sign-up, no watermark; files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours.

If You Actually Need a Scalable Vector

Wrapping a PNG in EPS will not make a logo print crisp at billboard size. That needs vectorization: detecting the shapes in the bitmap and refitting them as Bézier curves, so there are no pixels left to enlarge. On this site that job is PNG to SVG, which traces the image rather than embedding it, and works best on flat, high-contrast artwork — logos, icons, line drawings — not photographs. If the requirement is simply "give me a print-ready file" rather than "give me an EPS specifically", PNG to PDF is the modern hand-off: it compresses the image properly and every print workflow accepts it.

Frequently Asked Questions

Does converting PNG to EPS turn my image into a vector?

No, and no format converter can. The pixels of your PNG are embedded inside a PostScript wrapper; the shapes in the picture are never analysed or redrawn as paths. Blow the placed EPS up beyond its native resolution and it pixelates exactly like the PNG. Genuine vector output requires a tracing step — that is PNG to SVG here, or Image Trace in Illustrator and Trace Bitmap in Inkscape elsewhere.

Why is my EPS 12 MB when the PNG was only 200 KB?

Because the EPS stores the picture as uncompressed ASCII hexadecimal. The file declares PostScript LanguageLevel 1, which has no compression filter available, so every pixel is written as six hex characters of RGB. That makes the size a function of pixel count rather than image content: in our testing a 1920 × 1080 frame landed at about 12.6 MB whether it held a photograph or a logo on a transparent background. The one exception is an opaque image that fits inside a 256-entry palette, which takes a colour-mapped path instead — a 58-colour 1920 × 1080 graphic came out at 4,207,886 bytes rather than 12.6 MB. Any alpha channel rules that path out. To shrink the file, reduce the resolution percentage: the size scales with the area, so 50% resolution gives roughly 25% of the bytes.

What happens to my PNG's transparent background?

It becomes white, and semi-transparent pixels stop being semi-transparent. EPS has no alpha channel — Adobe's own position is that EPS is supported as a legacy format for "non-color managed, opaque graphical data". In our testing, pixels with an alpha of zero were written as pure white, while pixels at 75%, 25% and even 4% opacity were written at full opacity with their colour unchanged. The practical effect: a soft drop shadow or an anti-aliased edge comes out as a hard, fully saturated fringe. If transparency matters, flatten the PNG onto your intended background colour before converting, and keep the original.

Why would a print shop insist on EPS if it is just my PNG inside?

Because their pipeline is built on PostScript and their placement tools index on the bounding box, not on the image data. An EPS gives them a file their layout software will import and position deterministically, with a declared size in points. Whether the graphic inside is vector geometry or an embedded bitmap is a separate question — and one worth asking them, because if what they actually need is scalable line art, a wrapped PNG will not satisfy it no matter what the extension says.

Which programs will open the EPS I get back?

Adobe Illustrator and Photoshop, CorelDRAW, Affinity Designer, Inkscape, GIMP, Scribus and any Ghostscript-based viewer all read EPS. Microsoft Office is the notable exception: EPS insertion was turned off across Word, Excel and PowerPoint in the 11 April 2017 security update because EPS files can carry executable PostScript, and it has stayed off in every Windows Office release since — Office for Mac 2011 and 2016 were unaffected. Web browsers do not render EPS at all.

Is EPS still a current format, or should I be sending something else?

It is a legacy format that no longer evolves. Adobe has said it will keep supporting EPS for importing opaque legacy graphics but does not recommend storing new work in it, and PDF has taken over almost every job EPS used to do — better colour management, real transparency, and actual compression. Send EPS when a vendor's intake form demands .eps and nothing else; otherwise PNG to PDF is the better hand-off.

Can I control the DPI or the physical print size of the EPS?

Not from this page. The converter pins the density at 72 DPI so that one pixel maps to one PostScript point, which makes the bounding box match the pixel dimensions exactly. Your layout application is where physical size is decided — place the EPS and scale it there, or resize the image before conversion with the "Resolution Percentage" control if you want fewer pixels in the file to begin with.

Can I get my image back out of the EPS afterwards?

Yes. The original pixels are sitting inside the file, so EPS to PNG recovers the raster — minus anything you gave up on the way in, namely the alpha channel and any resolution reduction you applied. If your source was a JPG rather than a PNG, JPG to EPS wraps it the same way.

What happens to my files after the conversion?

They are uploaded over an encrypted connection, converted on our servers, and both the upload and the resulting EPS are deleted automatically after a few hours. No sign-up, no watermark, and nothing is shared or made public.
