Logo file formats explained: vector vs. raster

Vector vs. raster: the distinction that explains everything

Every graphic file is one of two things. Once you know which, most of the confusion disappears.

Raster files are grids of colored squares. A photo from your phone might be 4,000 pixels wide — that is the whole story, all the detail the file will ever have. Blow it up to a four-foot sign and the software has to invent pixels that were never there, smearing the ones it has. That is why enlarged images go soft and blocky. JPG, PNG, TIFF, and most Photoshop files are raster.

Vector files are not pictures at all. They are instructions: a curve starts here, bends this way, ends there, fill it with this color. There are no pixels to run out of, so the artwork redraws itself clean at any size — business card or billboard, same file, same crisp edges. AI, EPS, SVG, and many PDFs are vector.

Here is a ten-second test. Open your logo and zoom in hard, past the point of reason. If the edges stay razor sharp, it is vector. If they crumble into little squares, it is raster. File size proves nothing, by the way — a 12 MB JPG is still raster, and a 40 KB SVG still scales forever.

The vector formats: AI, EPS, SVG, and PDF

Four extensions cover nearly every vector logo you will encounter, and they are not interchangeable.

• AI — the native master

  Adobe Illustrator’s working file — where your logo was built, with every path, layer, and editable text intact. It is the file a designer opens to make real changes. Treat the AI as the original negative: you may never open it, but you should own a copy.

• EPS — the universal exchange format

  Encapsulated PostScript is old technology, and Adobe has been quietly phasing it out for years. It refuses to die because sign shops, embroiderers, and promotional-products vendors still ask for it, and almost any professional software can open one. When a vendor’s spec sheet says “vector EPS only,” send the EPS and move on.

• PDF — vector-capable and openable by everyone

  The useful middle ground. A PDF exported from vector artwork stays fully vector and scalable, but unlike AI or EPS it opens on any computer, so you can see what you are sending. The single most practical format to keep on hand.

• SVG — vector for the web

  Scalable Vector Graphics is the browser’s vector format. It stays sharp on any screen at any zoom, and the file is usually tiny. Your web developer wants this one.

The catch with PDF: the extension guarantees nothing. A PDF is a container, and a blurry JPG dropped into one is still a blurry JPG — now wearing a costume. Same with SVG, which can also wrap a raster image.

The raster formats: PNG, JPG, and TIFF

Raster files are not the enemy — just tools with a narrower job.

• PNG — raster with transparency

  PNG supports a transparent background, which is why it is the workhorse for logos on the web, in slide decks, and in email signatures — drop it on any background color and no white box appears. It is resolution-bound like any raster file, so a PNG sized for a website header will not survive being stretched across a banner.

• JPG — raster, no transparency

  JPG was built for photographs and is excellent at them. It cannot do transparency — that checkerboard becomes solid white — and it uses lossy compression, throwing away data to shrink the file. Every time you save a JPG again, it degrades a little more. Fine for photos. A poor home for a logo.

• TIFF — the heavyweight raster

  The lossless raster format, still requested by some print workflows for photographic art. It can be saved uncompressed or with lossless compression, so it does not throw away data the way a JPG does. The files get large, and it is still pixels — so it is not a substitute for vector.

The honest rule: raster is for photographs and for placing an already-correct logo at a known size. Vector is for the logo itself. If you are unsure whether a raster logo is big enough for a job, our image resolution checker tells you the effective DPI at your finished size, and the pixels-to-inches calculator converts the other direction.

What to send a printer, a sign shop, and an embroiderer

Different vendors need different things, and the reasons matter.

A printer wants vector, or a high-resolution raster at 300 PPI at final size. For a logo on a business card, a genuinely large PNG can hold up. But vector removes the guesswork, and the same file works for the card, the brochure, and the trade show booth. Our print-ready files guide covers the rest — bleed, safe area, color mode.

Anything that gets cut needs vector, and there is no workaround. A sign shop can print a banner or poster from a high-resolution raster file. Cut work is different, and this is the part people find surprising, so here is why. Cut vinyl lettering is produced by a blade that follows a path. The machine needs to know where the line is — mathematically, exactly. A raster file has no lines, only a field of pixels that happen to look like a line to your eye. The cutter cannot follow a suggestion. This is why vehicle graphics, cut lettering, and die-cut stickers come back with a request for vector art no matter how nice your PNG looks.

An embroiderer needs vector too, but it is only step one. Embroidery requires a digitized file — a stitch map telling the machine thread direction, density, and sequence. That digitizing is done from clean vector art. Fine detail and thin lines often have to be simplified, because thread cannot hold detail the way ink can.

“I only have a JPG of my logo” — the honest answer

This is the most common call we get about logo files, so let us be straight: there is no button that converts a JPG into real vector art.

Auto-trace tools exist. Illustrator has one, and web services promise instant vectorization. On a simple, high-resolution, black-and-white shape they can produce a usable starting point. On a typical logo — a JPG pulled off a website, compressed, with soft edges and color fringing — auto-trace faithfully reproduces the flaws. You get a vector file with hundreds of wobbly anchor points tracing every compression artifact. It passes the extension check and fails the eye test, especially blown up to sign size.

The real fix is redrawing. A designer opens your JPG as a reference layer and rebuilds the logo from scratch — true geometry, correct paths, live type set in the actual font (or drawn to match, if the font is lost to history). The result is a genuine master that scales cleanly forever.

It is a one-time job — we quote it before any work starts — and you never pay for it again. The alternative is paying for it in a hundred small ways: the sign that got rejected, the shirt that came back fuzzy, the trade show banner nobody wants to look at closely. If you are staring at a JPG right now, send it to us and we will tell you honestly whether it can be traced or needs a redraw.

Why the logo in a Word doc keeps failing you

Every design studio has a version of this story. A client needs their logo, cannot find the file, and eventually says: “It is in our letterhead — I will send you the Word doc.”

Here is what happened to that logo along the way. It went into Word as an image, which Word then compressed to keep the document small, and it has likely been copied, pasted, and resized across several documents since. What comes out the other end is a low-resolution raster image with none of its original quality, and pulling it out of the document does not recover anything — the data was thrown away years ago. Same story for a logo screenshotted from a website or saved from a Facebook post — both were compressed and downsized for their medium. A PDF is the one worth checking before you give up: if the flyer was built from vector artwork, the logo inside it may still be live vector, and a designer can pull it out intact. Open it, zoom in hard, and run the same test.

Canva creates a related trap: a logo built there lives inside Canva, and its exports are raster by default. Our Canva print guide covers how to export properly and where the limits are.

The pattern underneath all of this: a file only ever loses quality. Nothing you do downstream adds detail back. Which is exactly why the master file matters.

Own your masters: what to ask for at handoff

If you pay someone to design your logo, you should walk away with the source files. Not a PNG. Not a link to a portal. The actual editable originals.

Some designers hand them over without being asked. Some hold them and charge for every future export. Others simply never got asked and still have everything in a folder — one email away. Sort this out in writing before the project starts, not three years later when you need a banner and your designer has moved on. Ask for this package at handoff:

• The editable master

  The AI file (or equivalent source) with layers and live text intact. This is the file everything else derives from.

• Vector exports

  EPS and PDF for vendors, SVG for the web. These cover almost every request you will get.

• Raster exports at real sizes

  PNGs with transparent backgrounds at a few useful widths for slides, email signatures, and social profiles.

• Every color variation

  Full color, one-color black, one-color white (for dark backgrounds), and a grayscale version. You will need all four eventually.

• Your color values, written down

  The exact CMYK, RGB, HEX, and Pantone values. Our brand color guide explains why each one exists and how they relate.

• Font names

  Which typefaces the logo and brand use, and where they came from.

When we handle graphic design work, the files are yours. That should be the baseline anywhere.

Build the folder now, thank yourself later

Make a folder called Logo Files. Put every version in it. Back it up somewhere that survives a dead laptop and a departing employee — cloud storage, not one person’s desktop.

Then do the boring part that saves you every time: name the files so a stranger understands them. yourcompany-logo-fullcolor.eps beats logo_FINAL_v3_USE-THIS-ONE.eps by a mile. You know which file that second one is today. You will not in eighteen months, and neither will whoever replaces you.

When a vendor asks for artwork, you open one folder and send one file. That is the entire payoff. The businesses that have this sorted move fast on every print job; the ones that do not lose a day to archaeology every time.

If a term here sent you sideways, our print glossary defines the vocabulary in plain English. And if you have opened your logo folder, found nothing but a JPG, and are not sure what you are looking at — send us the file. We will tell you what you have and what it will take to fix it. No charge for the answer.

Frequently asked questions

• What is the difference between vector and raster?

  Raster files are grids of pixels with a fixed amount of detail, so enlarging them makes them blurry. Vector files are built from mathematical paths instead of pixels, so they scale to any size with perfectly sharp edges. JPG, PNG, and TIFF are raster. AI, EPS, SVG, and most properly exported PDFs are vector. A logo should always start as vector.

• What is an EPS file?

  EPS stands for Encapsulated PostScript. It is an older vector format that nearly any professional design or production software can open, which is why it became the standard way to hand vector artwork between a designer and a vendor. Adobe has been phasing it out, but sign shops, embroiderers, and promotional-products companies still request it constantly, so it remains worth keeping.

• What file do I need for my logo?

  Own the vector master (usually an AI file) plus vector exports as EPS, PDF, and SVG. Add transparent PNGs at a few sizes for web and slides. Send vector to any printer, sign shop, or embroiderer. Use PNG on websites and in documents. That set covers essentially every request a vendor will make of you.

• Can I convert a JPG to a vector file?

  Not automatically, with honest results. Auto-trace tools produce a technically vector file that faithfully copies the JPG’s blur and compression artifacts, giving you wobbly paths and lumpy curves that fall apart at large sizes. Simple high-resolution shapes sometimes trace acceptably. Most logos need to be redrawn from scratch by a designer, which is a one-time cost that fixes the problem permanently.

• Why does a sign shop need a vector file?

  For printed signage like a banner or poster, a sign shop can work from a high-resolution raster file. Cut work is the real constraint. Cut vinyl lettering and decals are produced by a blade that physically follows a path, so the machine needs to know exactly where every line sits mathematically. A raster file has no paths, only pixels that look like lines to your eye. No amount of resolution fixes that.
