Vector File: What It Is, Which Format, How to Get One

A vector file is a file that describes your logo with shapes (outlines, curves, flat areas of color) rather than tiny colored squares, so it stays sharp whether it’s shrunk or blown up. The usual formats are SVG, vector PDF, EPS and AI.

It’s the file your printer wants when they turn down your JPG, and you can make one for free from the logo you already have.

What is a vector file?

A vector file is a document that holds drawing instructions instead of a grid of pixels: “a curve from here to there, an area filled with blue”. Whatever program opens it recalculates those shapes at the size it needs, so one file works for a lapel pin and a billboard alike.

JPG, PNG and WebP files work the other way: they record the color of every little square, and they go blurry as soon as you enlarge them. How the two families differ, and the zoom test that tells them apart, is covered in what a vector image is. People say “vector image” for the picture itself and “vector file” for the thing you actually send: its format, its extension, and whether the shop can open it.

Why does your printer keep asking for a vector file?

Your printer asks for a vector file because their machines work from outlines, and because they almost always need to resize your logo. The same artwork ends up tiny on a pen and huge on a banner, and only a file made of shapes survives both without losing its edges.

Some techniques can’t even start without one. An embroiderer builds the stitch plan from the shapes (more on that in our guide to custom embroidered patches), vinyl cutters and laser engravers follow a path along the edges, and screen printers split each color onto its own screen. So a rejected file isn’t fussiness: the shop knows a JPG would come out badly.

What does it mean when someone asks for “a vector”?

When a printer, sign maker or embroiderer asks for “a vector”, they want a file where your logo is made of editable shapes, whatever name they give it. Depending on the shop, you may hear:

• “vector art”, “vectorized file” or “line art”: the same thing, worded differently;
• “outlined text” or “text converted to curves”: the letters have been turned into shapes, so the font no longer needs to be installed;
• “the source file” or “the native file”: the designer’s working file, often an .ai.

One request is easy to mix up with it: “high-res” or “300 dpi” means a large pixel image, not a vector. If you’re not sure which one they mean, ask the shop directly: “Do you want an SVG, a vector PDF, or a 300 dpi image?”

What are the main vector file formats?

The vector file formats you’ll run into are SVG, PDF, EPS, AI, DXF and CDR: they all hold shapes, but each one has its own home turf.

Extension	What it is	Who asks for it
.svg	Open format that displays in any web browser	Websites, cutting machines (Cricut, Silhouette), most printers
.pdf	The universal document, vector only if it was exported from a drawing program	Printers, flyers, posters
.eps	An older format for swapping artwork between programs	Screen printers, embroiderers, long-established shops
.ai	Adobe Illustrator’s working file	Designers picking up your logo
.dxf	The format of technical drawings and cutting machines	Laser engraving, signs, cut lettering
.cdr	CorelDRAW’s working file	Some sign and promotional product shops

The SVG deserves its own warning: some free converters wrap a pixel image in an .svg file without redrawing anything. The image to SVG conversion guide explains how to spot that fake. The PDF needs the same care, since it’s an envelope that can hold real shapes or a plain photo.

Which vector file should you send your printer?

The safest vector file to send is a vector PDF or an SVG, which most shops accept without any back and forth. An EPS only makes sense if the shop insists on it, and an AI file only if a designer needs to rework the logo. When in doubt, send the SVG and offer the PDF.

How can you tell if your file is a vector?

To tell if a file is a vector, check its extension first, then confirm by zooming in.

1. Never a vector: .jpg, .jpeg, .png, .gif, .webp, .bmp, .heic. However large, even with a transparent background, these are pixels.
2. A vector in the vast majority of cases: .svg, .eps, .ai, .dxf, .cdr.
3. Impossible to tell without opening it: .pdf.

Then zoom all the way in on the edge of a letter. A smooth edge means the shapes are there; a staircase of tiny squares means a pixel image was dropped inside the file. If all you have is a PNG, our guide to turning a PNG into a vector covers its specific traps, such as transparency and leftover backgrounds.

How do you open a vector file?

How you open a vector file depends on its format: a web browser is enough for an SVG and any PDF reader handles a PDF, while EPS, AI, DXF and CDR files need a drawing program.

Inkscape is free on Windows, Mac and Linux, reads most of these formats, and lets you change a color or fix a shape; Adobe Illustrator, sold by subscription, is what designers use. Our vectorization software comparison sorts the options by what they’re actually good at. Before you edit anything, keep an untouched copy of the original.

How do you get a vector file of your logo?

To get a vector file of your logo, first ask whoever made it, a designer or an agency, for the original: an .ai, .eps or PDF may still be sitting in an old email. If it’s truly gone, you have three options left: convert the image you have automatically, pay a designer to redraw it, or start the logo over. What to check in the result before it goes to the printer is in our guide to vectorizing a logo.

Automatic conversion, called vectorizing, handles most simple logos well: it rebuilds the shapes from the pixels. For the step-by-step method, see how to vectorize an image without software.

Get your logo as four files, one for each job

On Depixelise, you drop in your logo in whatever form it exists today (PNG, JPG, WebP or even SVG, 10 MB at most). Roughly ten seconds on, the vector version appears full size, ready to zoom. Four files reach you by email, each with its own job: the SVG for your printer, embroiderer or engraver; a 2000 px PNG with a transparent background for your website, social media and documents; a one-color version for engraving, rubber stamps or single-thread embroidery; and a reversed, light version for dark shirts and dark signs. Nothing to pay (it’s 100% free), no account, no watermark.

Two honest caveats: a very small starting image gets enlarged and its shapes rebuilt, and a two-color logo can lose a detail once it’s flattened to a single ink. Zoom in on the result and compare it with your original before you send it.

FAQ

Why would a printer reject a vector file?

A printer rejects a vector file when it’s only a vector on the surface: a pixel image tucked inside a PDF or an SVG. Other common reasons are text that was never converted to outlines, details too fine to embroider, or colors that need to be specified. Ask for the exact reason; it can almost always be fixed.

Can a vector file contain a photo?

Yes, a vector file can contain a photo, but the photo stays made of pixels: it will blur when enlarged, even while the shapes around it stay crisp. That’s where most “fake vector” PDFs come from.

Can you turn a vector file into a JPG or PNG?

Yes, Inkscape or Illustrator can save a PNG or JPG copy of a vector file at whatever dimensions you set. Keep the vector as your master and export one copy per use. Going the other way, from a JPG to a vector, takes real vectorizing.

Do you need paid software to make a vector file?

No, you don’t need paid software to make a vector file: Inkscape is free, and browser-based editors let you draw simple shapes online, as shown in our roundup of online vector drawing tools. To convert a logo that already exists, an online converter is enough.

Who can redraw a logo when automatic conversion falls short?

A graphic designer can redraw your logo by hand when automatic conversion distorts an important detail, such as a fine gradient or an unusual typeface. Pricing is by quote and depends on how complex the logo is.
