SVG vs EPS: Differences, When to Use Each, How to Convert

SVG vs EPS is not a question of quality — both are vector formats and both scale cleanly. It is a question of who has to read the file. SVG is markup that every browser draws. EPS is a PostScript program that only a PostScript interpreter can run: a printer’s RIP, Ghostscript, Illustrator. Use SVG for anything on a screen and as your master file, PDF for most print, and EPS only when a printer, a stock agency or an older piece of software asks for it by name.

SVG vs EPS: the short answer

If you only need the verdict, it is this. The rest of the post explains each line, including the parts the usual comparisons leave out — what is physically inside an EPS, why transparency goes wrong in it, and what you lose when you convert.

• Websites, apps, UI: SVG. Browsers render it natively; none renders EPS.
• Commercial print: PDF, unless the printer’s file spec says EPS. Then EPS, with text outlined.
• Cricut and other cutters: SVG. Cricut Design Space does not list EPS as an upload type at all.
• Stock agencies: whatever the agency names. Shutterstock still requires EPS; Adobe Stock also takes SVG.
• Your master copy: SVG, or your editor’s native file. Never EPS — Adobe’s own Illustrator documentation now steers people away from it.

What an EPS file actually is

EPS stands for Encapsulated PostScript. Adobe’s EPSF 3.0 specification (Technical Note 5002) defines it as a PostScript program describing a single page, written under a few extra rules so another program can place it inside its own page. The UK National Archives’ format registry, PRONOM, dates that version to 1 May 1992. Two header lines are mandatory: %!PS-Adobe-3.0 EPSF-3.0, which says what the file is, and %%BoundingBox, four numbers giving the rectangle the drawing occupies.

• It is a program, not a picture. PostScript is a full programming language. An EPS paints its image by running — which is why it needs an interpreter, and why it can be a security problem.
• It can hold pixels. PostScript paints paths, text and bitmap images alike, and Adobe’s Illustrator help says plainly that EPS files can contain both vector and bitmap graphics. The .eps extension promises nothing about scalability.
• It usually carries a preview. Layout programs mostly cannot run PostScript, so the file can include a low-resolution bitmap to show on screen: a Mac PICT resource, a TIFF or Windows Metafile behind a binary header that starts with the bytes C5 D0 D3 C6, or a hex bitmap in comments (EPSI). With no preview, the spec has the host program draw a stand-in, such as a grey box. That preview is what you see; the PostScript is what prints.
• It speaks print colour. PostScript works in RGB, CMYK and spot colours, which is the main reason prepress adopted it.

<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 100 100">

       the top-left corner and y grows downwards. -->
  <circle cx="50" cy="50" r="40" fill="#f97316"/>
</svg>

The differences are small on the page and large in practice:

• Units and origin. EPS measures in points from the bottom-left with y pointing up, so the file has a physical size: this one is 80 pt square, about 28 mm. The SVG measures in user units from the top-left with y pointing down, and has no physical size until a browser or converter gives it one.
• The box. The spec wants %%BoundingBox to be the smallest rectangle around the marks, so the 10-unit margin the SVG’s viewBox keeps around the circle is gone. Converters do the same, as the conversion section shows.
• Colour. The EPS names ink percentages. The SVG names an RGB hex value, and there is no CMYK alternative a browser will honour: MDN’s page for device-cmyk() records that no browser supports it.
• Who can display it. Drag the SVG into a browser tab and it draws. The EPS needs Ghostscript, Illustrator or a printer.

SVG vs EPS, feature by feature

Why EPS is still asked for

EPS survived because nearly every layout program, prepress system and PostScript printer accepted it — Adobe’s Illustrator help still says virtually all page-layout and graphics applications import it. Three groups still lean on it.

• Print shops with older specs. File requirements written when PostScript was the printer’s native language still say EPS. Many have moved on — Vistaprint’s upload help, for example, names PDF and AI among its common file types and does not mention EPS or SVG.
• Stock agencies. Shutterstock requires vectors saved as EPS 8 or EPS 10 and treats any other vector format as unsuitable. Adobe Stock accepts AI, EPS or SVG. If you buy or sell stock vectors, expect EPS to stay in the mix.
• Older software tiers. In Silhouette Studio, the Designer Edition opens SVG and PDF, while EPS import needs the Business Edition.

Where EPS causes trouble

• No browser shows it. EPS is absent from MDN’s guide to web image formats, and putting one in an <img> gets you a broken image.
• Desktop support is shrinking. Microsoft turned off EPS insertion in Office with the 11 April 2017 security update, citing malicious attacks, and in Microsoft 365 and Office 2019 or later there is no way back; it suggests SVG or EMF instead. Apple says macOS no longer includes built-in support for viewing .eps files; Preview handled them up to macOS 12.
• Transparency does not exist. PostScript has no notion of partial opacity. Areas you never painted stay see-through, so a logo with no background still sits cleanly on a coloured page, but a drop shadow, a 50% overlay or a soft glow must be flattened. The Inkscape manual says transparent objects are rasterised on PostScript export; Illustrator flattens them with a transparency flattener preset.
• The preview can lie. What a layout app shows is the embedded bitmap, not the artwork. Shutterstock’s requirements spell out that the on-site preview must match the EPS contents — a rule that only needs writing because the two can differ.
• Fake vectors. An EPS that is a single photo wrapped in PostScript is still a valid EPS. Check before you trust one:

# 1. Plain PostScript, or a binary wrapper carrying a preview?
file logo.eps
#   PostScript document text conforming DSC level 3.0, type EPS
#   DOS EPS Binary File Postscript starts at byte 30 ... TIFF starts at byte ...

# 2. What size does it claim? Points, measured from the bottom-left.
grep -a -m1 '%%BoundingBox' logo.eps

# 3. Is it really vector? Convert it to plain SVG and count the
#    embedded bitmaps. Inkscape reads EPS through Ghostscript,
#    so install Ghostscript first.
inkscape --export-plain-svg --export-filename=check.svg logo.eps
grep -c '<image' check.svg

Anything above zero on the last line means a bitmap is inside. One small image may be a texture; one image the size of the whole artwork means the file was never vector.

Is EPS outdated?

As a working format, yes. The note heading the EPS section of Adobe’s Illustrator help says the format, “commonly used in the past, isn’t suitable for modern workflows.” Its specification is still EPSF 3.0 from 1992, while PDF took over its job and added what it lacked: real transparency and multiple pages in one file. Inkscape’s manual notes that PDF export keeps an SVG’s transparency where EPS export cannot.

As a delivery format, it is alive wherever someone’s pipeline asks for it. Treat it like a fax number: keep the ability to send one, do not store anything in it.

A related question comes up a lot: is SVG the same as AI or EPS? No. AI is Illustrator’s own format — modern AI files are PDF-based, and Silhouette’s support notes distinguish those from the older EPS-style AI files. EPS is PostScript. SVG is an open W3C text format. All three can hold vectors; only SVG is meant to be read by a browser.

Which to send: print, Cricut, stock, web

Every claim about a company’s accepted formats below comes from that company’s own page, linked. When a printer or platform is not listed, ask for its file spec rather than guessing — the spec beats any blog post, this one included.

SVG vs EPS for logos

For a logo the answer is both, for different people. SVG goes to whoever builds the website or app; PDF goes to the printer, with EPS kept for the vendor whose spec still names it; PNG goes anywhere that only takes raster. Outline the wordmark in every print file so a missing font cannot change the lettering. The full handover kit — favicon sizes, colour variants, how to spot a fake vector logo — is in the logo file formats guide.

How to convert SVG to EPS or PDF

Plainly: SVG Maker AI exports .svg, a PNG capped at 1024 px, a base64 data URI and a React component. It does not export EPS, PDF or AI, and nothing in it does CMYK. One thing works in your favour — the server removes any <image> element from generated files, so there is no hidden bitmap to carry into an EPS. Converting is a job for Inkscape, which is free and has a command line. These are the 1.x flags, checked against the manual on inkscape.org:

# SVG to EPS. Text becomes outlines, and anything Inkscape has
# to rasterise (filter effects) is rendered at 300 dpi, not 96.
inkscape --export-filename=logo.eps --export-text-to-path --export-dpi=300 logo.svg

# SVG to PDF. Same options; transparency survives as transparency.
inkscape --export-filename=logo.pdf --export-text-to-path --export-dpi=300 logo.svg

# A whole folder, both formats, each named after its source file.
inkscape --export-type=eps,pdf --export-text-to-path --export-dpi=300 *.svg

# These are Inkscape 1.x flags. 0.92 and older used -E / --export-eps.
# Check what you have with: inkscape --version

Before converting, decide the physical size. A file straight from the generator has a viewBox and no width or height, and one exported from the editor is sized in pixels, so either way the converter is guessing at the size on paper. Give it real units:

<!-- A viewBox alone has no physical size. Give the root
     element one before converting; nothing inside changes. -->
<svg xmlns="http://www.w3.org/2000/svg"
     viewBox="0 0 1024 1024"
     width="50mm" height="50mm">
  <!-- your paths, unchanged -->
</svg>

What can change on the way, and what to do about it:

• Transparency. In EPS, transparent objects are rasterised. If the artwork uses opacity or soft shadows, send PDF, or flatten them into solid shapes first.
• Filters. Blurs and other filter effects are rasterised at --export-dpi, 96 by default — hence 300 above. --export-ignore-filters drops them and keeps everything vector.
• Fonts. Inkscape embeds a subset of the fonts used, but outlining is safer for logos. Our SVG editor cannot convert text to outlines, so let --export-text-to-path do it at export. When to outline text covers the trade-off.
• Colour. Values stay RGB. The Inkscape FAQ says it does not colour-manage export, so CMYK conversion happens at the printer’s RIP or in a layout tool such as Scribus.
• Margins. EPS export uses the drawing’s bounding box, and the manual says page-area export is not supported for EPS, so viewBox padding is trimmed.

Going the other way: EPS to SVG

The third command in the check above is also the conversion: Inkscape reads the EPS through Ghostscript and writes plain SVG. If the EPS held a bitmap, the SVG will hold the same bitmap in an <image> — conversion never invents vectors that were not there.

Where to go next

To make the SVG in the first place, start from a prompt with text to SVG, or from the AI logo generator if it is a mark or wordmark. Heading to a cutter? The Cricut SVG guide covers what Design Space wants. Need to tidy the markup before handover? Use the SVG editor.

On the blog, SVG vs PNG covers the raster side of the same decision, what an SVG file is starts from first principles, and optimising SVG shrinks the file once it is final.
