Logo files are not interchangeable: the right format affects sharpness, transparency, editing, print quality and how consistently your brand appears. This practical guide explains SVG, PNG, JPG, PDF, EPS and other common logo design files, then gives you a simple system for checking your logo assets across websites, print materials and social media.
Overview
A complete logo handover should contain more than one file. Different channels require different technical properties. A website may need a lightweight SVG with a transparent background, while a printer may request a vector PDF or EPS. A social platform may work best with a square PNG, and an editable source file can be useful when your visual identity changes.
The key distinction is between vector and raster artwork. Vector logos are built from mathematical paths, so they can usually be scaled from a small label to a large sign without becoming pixelated. Raster logos are made from pixels. They are practical for screens and photographs, but they have a fixed resolution and may look soft when enlarged.
Before downloading or exporting anything, identify the intended use, background and required size. Keep an organised master folder with the original logo artwork, approved exports, colour variations and a short brand style guide. The brand asset checklist for a new business launch can help you review the wider set of files around your logo.
What to track
SVG: the flexible digital option
SVG, or Scalable Vector Graphics, is a vector format designed for digital use. It can remain sharp at different screen sizes and is often suitable for websites, interfaces, email signatures and some digital design tools. An SVG may also support a transparent background, which makes it useful when the logo needs to sit over a coloured section.
Check that the SVG has been exported cleanly and that any fonts have been converted to outlines or are otherwise handled reliably. Test it on both light and dark backgrounds. Some platforms do not accept SVG uploads, so keep a transparent PNG available as a fallback.
PNG: transparent raster artwork
PNG is a raster format that can preserve transparency. It is a practical choice for social media graphics, presentations, documents, online marketplaces and tools that do not accept vector files. Export separate versions for light and dark backgrounds if your logo includes fine detail or low-contrast colours.
A PNG should be exported at a sufficiently large pixel dimension for its intended use. A small PNG may look acceptable in a browser but become blurred in a printed document or a large social graphic. Keep a high-resolution master PNG and create smaller copies as needed.
JPG: a compact option with a background
JPG files are widely supported and can be relatively small, but they do not support transparent backgrounds. They are therefore best used when the logo sits on a known solid background, such as a white document or a prepared image. Repeatedly opening and saving JPG artwork can introduce compression artefacts around edges, so avoid treating it as your master logo file.
PDF: useful for sharing and print
A PDF can preserve vector artwork, colour information and layout in a file that is easy to share. It is commonly useful for print logo files, stationery proofs, signage artwork and approval documents. However, not every PDF contains editable vector paths: some are simply raster images placed inside a PDF. If a printer or designer requests a vector PDF, confirm that the artwork remains vector-based.
EPS: a legacy-friendly vector format
EPS is an editable vector format that remains part of many professional print workflows. It can be useful when a supplier or design application specifically asks for it. It is less convenient for everyday web use, and it may not preview correctly in ordinary file browsers. Keep it in the master asset folder rather than using it as your default social or website upload.
AI and other source files
AI files are native Adobe Illustrator working files. They may contain separate layers, colour versions, typography and construction details that are not present in a final PNG or JPG. Other design tools may use their own source formats. Keep the original source file if you may need future logo redesign work, packaging adaptations or brand identity design updates.
Build a practical logo file set
A useful handover normally includes:
- Full-colour logo in vector format, such as SVG, PDF or EPS.
- Transparent PNG in a large export size.
- JPG version for simple documents or platforms requiring a solid background.
- Reversed or white logo for dark backgrounds.
- Black or one-colour version for low-cost print and single-colour applications.
- Icon or symbol-only version where the full company logo will not fit.
- Editable source file, where available and appropriate.
- Short notes covering colour values, minimum size, clear space and approved backgrounds.
File names should describe both the logo variation and format. For example, use names such as company-logo-full-colour-transparent.svg or company-logo-reversed-large.png instead of vague names such as final2.png. This small habit prevents the wrong version being used later.
For a wider identity review, see the small business brand identity checklist. It covers the relationship between a logo, typography, colour and other brand assets.
Cadence and checkpoints
Logo assets do not need to be replaced on a fixed schedule, but they should be checked whenever your business adds a channel, changes its name or refreshes its visual identity. A quarterly review is a practical habit for an active small business; a monthly check may make sense during a launch or rebrand.
Monthly check
- Confirm that the logo used on your website is the approved version.
- Check new social profiles, adverts and presentation templates for distorted artwork.
- Remove duplicate files that could cause confusion.
- Open one file from each main format to ensure it is not corrupted.
Quarterly check
- Review every logo variation against your current brand guidelines.
- Test the logo at small sizes and on both light and dark backgrounds.
- Check that print suppliers still have the preferred vector files.
- Review folder permissions and keep a backup of source artwork.
- Record any new channel that needs a dedicated export, such as a marketplace profile or event display.
When creating a new logo or commissioning custom logo design, include these requirements in the logo design brief. The small business logo design brief template can help you specify variations, backgrounds, file formats and intended applications before work begins.
How to interpret changes
A problem with a logo file does not always mean the logo itself needs changing. If it looks blurry on a website, check whether a low-resolution PNG has been enlarged before considering a logo redesign. If it disappears on a coloured background, the issue may be the missing reversed version or insufficient contrast. If a print supplier cannot use the file, provide a vector PDF or EPS rather than sending another compressed JPG.
Look for recurring problems across channels. One incorrect upload may be an isolated process error. Several teams using different colours, proportions or symbols suggest that the brand guidelines need clarification. If staff repeatedly crop the logo to make it fit, create a suitable icon or compact lock-up rather than allowing inconsistent cropping.
When comparing files, check four things: proportion, colour, background and legibility. The logo should not be stretched, recoloured without approval, placed over a competing image or reduced below a size where its details become unclear. Record the preferred solution in your brand style guide so the same question does not return each time an asset is needed.
When to revisit
Revisit this logo file checklist whenever you launch a website, open a new social profile, order printed materials, join a marketplace, change suppliers or update your brand identity. It is also worth reviewing after a logo redesign, business name change, merger or expansion into a new product range.
Use this quick handover check before marking the asset folder complete:
- Identify the channels where the logo will appear.
- Choose vector files for scalable artwork and transparent PNG files for practical digital uploads.
- Provide a JPG only where a solid background and broad compatibility are needed.
- Include print-ready PDF or EPS files when requested by a supplier.
- Add black, white, full-colour and symbol variations where the applications require them.
- Open-test each file and check it on light and dark backgrounds.
- Label files clearly, archive the source artwork and update the brand guidelines.
Keep the checklist with your brand assets and review it monthly during active launches, then quarterly once your visual identity is stable. This simple routine makes logo files easier to find, reduces avoidable production errors and helps your business present a consistent identity wherever customers encounter it.
