Most businesses need a small set of logo files: a master vector file, an SVG for the web, transparent PNGs for everyday use and a PDF for print. Vector files describe shapes and scale to any size, while raster files are fixed grids of pixels. If you hold the vector master, you can create the rest. If you only have a PNG, you are limited.
Vector versus raster
Vector graphics are drawn with shapes and paths, so they can be enlarged without losing sharpness. Raster graphics are made of pixels and degrade when enlarged beyond their original size.
MDN describes SVG as scalable and resolution independent, so images “can be rendered at any size without loss of quality,” and notes it is a text-based, XML-based web standard that can be created and edited with a text editor or drawing software (MDN, SVG).
The formats and what each is for
MDN’s image types guide supports the following summary for web use (MDN, Image file type guide):
| Format | Type | Transparency | Best used for |
|---|---|---|---|
| SVG | Vector | Yes | Logos and icons on websites, scalable use |
| PNG | Raster, lossless | Yes (full alpha) | Fallback logo, slides, documents, social profile images |
| JPEG | Raster, lossy | No | Photographs, not logos |
| WebP | Raster, lossy or lossless | Yes | Smaller web images, with a fallback |
| Document format that can hold vector and raster | Varies | Print and sharing with printers and designers |
The guide’s recommendation for logos is to use SVG whenever possible, and PNG (or WebP with a PNG fallback) when only raster versions exist. JPEG blurs sharp edges and text and cannot be transparent, so it suits logos poorly.
Note that the MDN guide covers web formats. PDF, and source formats such as AI or EPS from design software, are widely used in print workflows, so confirm with your printer which they prefer.
A practical delivery package
Ask your designer for, or create, the following:
- Master vector file in the design software’s native format, plus a clean PDF or SVG export
- Primary logo and variations: full colour, one-colour, reversed (for dark backgrounds), icon or monogram, horizontal and stacked versions where they exist
- SVG files of each variation for the website
- PNG files with transparent backgrounds in several sizes
- Print-ready PDF versions
- A short usage guide: clear space, minimum size, colours, misuse examples
Name files consistently, for example brand-logo-horizontal-fullcolour.svg, so no one has to guess. This is part of keeping a brand coherent; see building a consistent visual identity across digital channels.
Choosing the right file for the job
- Website header: SVG, with a PNG fallback only if needed
- Email signature: PNG, since support for SVG in email clients is uneven (test in the clients that matter to you)
- Social profile images: PNG at the platform’s required dimensions, which you should confirm in the platform’s help pages
- Slide decks and Word documents: PNG with transparency, or SVG where the software supports it
- Printers and signage: PDF or vector file, with colours specified to the printer’s requirements
- Embroidery and merchandise: vector file, plus a simplified version if details are too fine
Common mistakes
- Receiving only a JPEG, which has no transparency and looks soft when scaled
- Enlarging a small PNG for print
- Using a white-background file on a dark page
- Stretching a logo out of proportion
- Not storing the original vector files, then having to redraw them
- Using a logo with fine detail at very small sizes, where a simplified version works better
Quality and premium impression
Product imagery deserves the same care, as discussed in product photography vs AI-generated product imagery. Crisp, consistent logo handling is a quiet signal of care, one of the cues covered in what makes a brand look premium. Fuzzy edges, wrong colours or mismatched versions weaken it quickly.
A short checklist
- Do you have the vector master?
- Do you have SVG and transparent PNG for every variation?
- Do you have a print-ready PDF?
- Are the files named clearly and stored in one shared location?
- Does a written guide describe how to use them?
