Wrong Logos: How to Tell When a Logo File Isn't the One You Need
A practical guide to spotting a wrong logo file: incorrect versions, raster images disguised as vectors, mismatched colours or fonts, and artwork you aren't permitted to alter.
Contents
The short answer
A logo is usually "wrong" in one of two ways. It may be the wrong artwork: an outdated version, a lookalike, a redrawn copy, or a variant meant for a different background or use. Or it may be the right design delivered in the wrong form: a flattened raster image presented as a vector, a file with fonts that won't render, or a colour set-up that doesn't match the job. Both problems are fixed by checking what the file actually contains, not what it is called, and by confirming the artwork against an authoritative source such as the brand owner or the designer who made it.
No specific logo, brand or file was provided for this article, so it can't say whether any particular logo is correct. What follows explains what to check and why each check matters.
Wrong artwork: the design itself doesn't match
- Outdated versions: brands revise their marks, and old files keep circulating in shared folders, image searches and supplier archives.
- Unofficial redraws: someone has traced or rebuilt the logo by hand, often with slightly different curves, spacing, proportions or typefaces.
- Wrong variant: a horizontal lockup used where a stacked one is needed, a full-colour version placed on a dark background meant for a reversed version, or an icon used where the full wordmark is required.
- Wrong entity: a similarly named company, a sub-brand or a former parent brand.
These errors can't be confirmed from the file alone. The dependable check is a comparison with artwork or guidelines issued by the brand owner. If neither is available, treat the file as unverified rather than assuming it is current.
Wrong form: the right design in the wrong kind of file
This is where the difference between vector artwork, embedded raster images and raster previews matters most.
- Vector artwork is made of paths and shapes. It scales cleanly and you can edit individual elements.
- An embedded raster image is a pixel image placed inside a vector-capable file. It can look like a vector container, but it blurs or pixelates when enlarged and you can't edit it as paths.
- A raster preview is a pixel thumbnail or preview image stored alongside, or instead of, the real artwork. Some viewers show the preview, so a file can look fine until it is opened in an editor.
A file extension doesn't settle the question. Formats such as SVG, EPS, PDF and AI can hold true vector paths, but they can also hold nothing more than a pasted-in photo of a logo. A file renamed from a pixel format to a vector extension isn't a vector at all. You have to look inside the file to confirm it contains editable paths.
How to check a logo file
- Open it in a vector editor rather than an image viewer or browser preview.
- Switch to an outline or wireframe view. Real vector shapes appear as path outlines. An embedded image appears as a single rectangle or shows nothing useful.
- Select elements and look at what the editor reports: paths, groups, text objects or placed images.
- Zoom in well beyond normal size. Edges that stay crisp suggest vector paths. Visible pixels suggest raster content.
- Check the text. Live text needs the original font installed and may be substituted on another machine. Text converted to outlines keeps its appearance but can no longer be retyped.
- Check the colour set-up against the intended output, for example spot or process colours for print and screen colours for digital use, using brand guidelines where they exist.
| Symptom | Likely cause | What to do |
| Blurry or jagged edges when enlarged | Embedded or flattened raster image | Request true vector artwork from the source |
| Outline view shows only a box | Placed image rather than paths | Treat as raster regardless of extension |
| Typeface changes when opened | Live text with a missing font | Get the font legitimately or ask for an outlined version |
| Colours differ from brand material | Wrong colour mode or unofficial file | Check against brand guidelines or the issuing designer |
| Shapes or spacing differ from official use | Redrawn or outdated version | Replace with owner-supplied artwork |
Correcting a wrong file without creating new problems
The safest fix is to get the correct artwork from whoever controls it: the brand owner, their agency or the original designer. Auto-tracing a raster logo into paths can produce a usable approximation, but the result is a new interpretation, not the original artwork. It often differs in curves and letterforms, so it shouldn't be passed off as official.
Permission is a separate question
Being able to download a logo doesn't mean you may change it, or even use it for every purpose. Three things are distinct: access to the file, rights in the artwork, and rights in the trademark it represents. Fonts inside the logo can carry their own licence terms as well. Many brand owners publish usage rules that limit recolouring, stretching, cropping or combining the mark with other elements. Even when a file is technically wrong, "fixing" someone else's logo yourself may break those terms. Where permission isn't clear, ask the rights holder before you edit or publish.
What this article can't confirm
No sample files, brand guidelines or test results were supplied, so nothing here is a verdict on any specific logo. The checks above describe general ways that vector editors and file formats behave. Whether a particular file is the correct, current and permitted version can only be confirmed by inspecting that file and checking with its owner.
