Why I Need Your Vector Files

(And What Happens If You Don't Have Them)

Every designer has had this conversation. A client sends through their logo, I open it up, and it's a 400 pixel wide JPEG that's been screenshot off their own Facebook page. It's a bit blurry. There's a white box around it. And they need it on a car by Friday.

If that sounds familiar, don't stress. Most business owners have never been told what file types they should have, let alone why it matters. So here's the plain English version.

What a vector file actually is

There are two ways a computer can store an image.

The first is pixels. Think of a mosaic made of tiny coloured squares. That's your JPEG or PNG. It looks great at the size it was made, but blow it up and those squares get bigger and blockier until your logo looks like it was printed on a wet newspaper.

The second is maths. Instead of storing squares, the file stores instructions: draw a line from here to here, curve it like this, fill it with this colour. That's a vector file. Because it's instructions rather than fixed dots, it can be scaled to any size at all with zero loss of quality.

That's the whole thing – pixels have a limit, vectors don't.

How to tell what you've got

Have a look at your logo file name and check the bit after the dot.

Vector Files (the good stuff)	.AI (Adobe Illustrator)	.EPS	.SVG	.PDF
Raster files (pixel-based)	.JPG	.PNG	.GIF	.WEBP

A PNG with a transparent background is still a PNG. It's very handy, and you'll use it constantly for social media and documents, but it is not a vector file and it won't save you when the signwriter asks.

Where it really matters

For everyday web stuff you'll barely notice the difference. Where it bites is anything physical or anything big.

• Vehicle signage and wraps. Your logo is going on at roughly a metre wide. A file made for a website is nowhere near enough information for that.

• Signage and banners. Same deal. Site hoardings, building signage, event banners, pull up banners at the home show.

• Embroidery. Uniforms, caps, jackets. Embroidery machines need clean defined shapes, and a fuzzy JPEG gives them nothing to work with.

• Screen printing and merch. Printers usually need each colour separated out. That's only possible with vector artwork.

• Motorsport livery. If you've seen a car with slightly soft, slightly wrong looking sponsor logos, that's a raster file that's been stretched to fit. On a car doing 100kph past a photographer, it shows.

• Anything laser cut, routed, engraved or CNC'd. These machines literally follow the vector path. Without one, there's nothing to follow.

What happens when the vector doesn't exist

Two options, and neither is free.

The first is that we print it anyway and it looks average. Soft edges, a faint halo around the letters, colours that don't quite match your other gear. Nobody says anything to your face, but it undercuts the impression you're paying to make.

The second is that someone redraws it from scratch. That means tracing your logo by hand in Illustrator, matching the fonts, rebuilding the shapes, and getting the colours right. It's completely doable and I do it regularly, but it's an extra job with an extra cost that you'd have avoided by having the files in the first place.

There's also a third scenario worth knowing about. Sometimes the printer's software will auto trace a raster file to force it through. The result is technically a vector, but it's full of wobbly edges and stray anchor points. It's the difference between a proper repair and gaffer tape.

But my logo looks fine on my website

It does, and that's the trap. Screens are forgiving. Your monitor is showing your logo at maybe 300 pixels wide and everything looks crisp.

Print is not forgiving. A print job needs several times more detail than a screen, and physical signage more again. The file that looks perfect in your email signature can fall apart the moment it hits a large format printer.

What to ask for from now on

When you get any logo or branding work done, ask for a full file pack. A decent designer will hand this over without being asked, but it's worth saying it out loud:

• The original vector artwork (.ai or .eps)

• An SVG for web use

• PNGs with transparent backgrounds, in a few sizes

• A JPEG version for anywhere that won't accept transparency

• Full colour, single colour, and reversed (white) versions

• Your colour codes in CMYK, RGB and HEX

• Your font names

Then back the whole lot up somewhere that isn't just your laptop. Google Drive, Dropbox, a hard drive, all three ideally. I've had clients lose an entire brand because the designer they used five years ago has moved on and their old computer is long gone.

If you don't have them, it's fixable

Honestly, this is not a crisis. Redrawing a logo into proper vector artwork is a normal part of what I do, and it's often a good moment to tidy up the bits that have always bugged you. Wonky spacing, a colour that never quite worked, a version that's slightly different on your van than on your website.

Send me whatever you've got, even if it is a screenshot from Facebook. I'll tell you honestly whether it needs a full rebuild or just a clean up, and what that looks like cost wise.

Once it's done, it's done. You'll have one folder that works for every printer, signwriter and embroiderer you ever deal with, and you'll never have to send another blurry logo again.
