The printer asks for a vector file and you do not know what that means. The sign company says your logo is too low resolution. A directory rejects your upload because the file is too large. Social media crops it awkwardly. Someone asks for a version "without the white background".
Each of these feels like a separate annoyance. They are the same one. You have the wrong format for the job in front of you. You were given a single logo file, and a single file cannot do all of those jobs.
The root cause
A logo is not a picture. It is a design that needs to appear in a dozen different places, each with its own technical demands. A business card and a billboard, a dark website header and a white letterhead, an embroidered polo shirt and a favicon in a browser tab.
Those places need different files. Not resized copies of one file, different files, exported for different purposes.
When a logo is handed over as one JPG, or one PNG at one size, every future use becomes a conversion problem. You are not doing anything wrong by struggling with it. You were handed one tool for twenty jobs.
The five problems you are probably hitting
1. The printer wants vector
Printers ask for AI, EPS, PDF or SVG because those files store your logo as shapes rather than pixels. A shape can be printed at any size, from a pen to a vehicle wrap, with perfectly crisp edges. A pixel image has a fixed resolution, and enlarging it produces soft, blocky edges.
If you cannot supply vector, the printer either redraws your logo by hand, which costs money and rarely matches, or prints something slightly blurry.
2. The white box
Your logo appears with a white rectangle behind it on anything that is not a white background. That means the file is a JPG, which has no way to store transparency. The fix is a PNG or SVG exported from the original, not a conversion of the JPG. We cover the detail in transparent backgrounds explained.
3. It looks wrong on dark backgrounds
A logo in dark navy is invisible on a dark website header or a black T-shirt. This is why a proper handover includes a reversed version, usually white or very light, built specifically for dark backgrounds rather than just inverted.
4. It is unreadable when small
A logo with fine detail, a tagline and thin strokes looks excellent at the top of a letterhead and turns to mush as a 32 pixel app icon. The answer is a simplified mark, sometimes just the symbol or the initial, made for small sizes.
5. The file will not upload
Upload forms reject files for being too large, the wrong dimensions, or a format they do not accept. This is usually solved with an appropriately sized copy rather than the master file, which is often several thousand pixels wide.
If you find yourself opening a design tool or a converter every time someone asks for your logo, that is the symptom. The cause is an incomplete handover, and it is worth fixing once rather than working around forever.
What a complete logo handover contains
Here is what should have been delivered, and why each piece exists.
Vector source files
AI or EPS as the master, plus SVG for web use and PDF for sending to printers. These scale infinitely and are the files everything else is exported from. If you only keep one thing, keep these.
Raster exports
PNG with transparency at several sizes, typically something around 2000px for general use, 1000px for documents and web, and a few small sizes for icons and favicons. JPG versions on a white background for the places that will not accept PNG.
Color variations
Full color, the primary version
Reversed, for dark backgrounds
Single color, for one color printing, stamps, embroidery and engraving
Black and white, for faxes, low quality print and photocopying
Layout variations
A horizontal version for website headers and letterheads, a stacked or square version for social profiles and app icons, and a simplified mark for very small sizes.
A brand guide
Even a single page is enough, covering the exact color values in HEX, RGB and CMYK, the fonts, the minimum size, and how much clear space to leave around the mark. This is what stops the logo drifting as different people use it.
What to do if you do not have these
Ask the original designer
Start here. They almost certainly still have the source files, and many will send them on request. Ask specifically for "the vector source files, AI or EPS", not "the original files", which is vague enough to get you another PNG.
Be aware that in some arrangements the designer retains ownership of the source files and only licenses the exports. Check what you actually bought. This is one reason to confirm full ownership before commissioning work.
Convert what you have, as a stopgap
If you need a usable file today, converting buys you time. Our WebP to PNG and AVIF to JPG converters run in your browser and handle the common web formats. The full set of tools is free with no account.
Be clear about what this does and does not solve. Converting changes the container, not the contents. A 500px logo converted to PNG is still 500px, and still too small for print.
Have it rebuilt as vector
If the source files are genuinely gone, the logo can be redrawn as vector from a good quality image. Done properly this is a manual redraw rather than an automatic trace, and the result is a true vector file that scales to anything.
This is also the natural moment to ask whether the logo is still right. If it is being rebuilt anyway, it is worth considering whether it is doing its job.
How to avoid this next time
Before commissioning any logo work, confirm these points in writing.
You receive the vector source files, not only exports
You own the design outright, with no ongoing license
The delivery includes color variations and layout variations
The delivery includes transparent PNGs at multiple sizes
Color values are documented for both screen and print
Those five points are the difference between owning a logo and renting a picture of one. Our logo design service includes all of them as standard, because the alternative is exactly the situation this article describes.
What format should I send my logo to a printer?
Vector, which usually means AI, EPS or PDF. Printers need vector because it can be scaled to any size without losing sharpness, from a business card to a vehicle wrap. If you can only supply a PNG or JPG, the printer will either redraw the logo manually, which costs extra, or print something slightly soft.
Why does my designer only give me a PNG?
Sometimes it is an oversight, and asking directly resolves it. Sometimes the arrangement only licensed the exports rather than transferring the source files, which is worth checking against what you agreed. Either way, ask specifically for the vector source files in AI or EPS format.
Can I convert a PNG logo to vector?
It can be redrawn as vector, which is different from converting. Automatic tracing tools produce a vector file quickly, though the curves are usually rough and the result does not match the original precisely. A manual redraw by a designer gives a clean, accurate vector file. Either way the original source files are always the better option if they exist.
How many logo files should I actually have?
A typical complete set is somewhere between fifteen and thirty files, covering vector sources, transparent PNGs at several sizes, JPGs, and color and layout variations. It sounds excessive until the first time someone asks for a white version for a dark background and you already have it.
What size should my logo file be?
For raster files, at least 2000px on the longest edge as a master, with smaller exports made from it. For print, work from the vector file instead, since vector has no fixed size at all. Never enlarge a small raster file to meet a size requirement, because the result is visibly soft.
