You just received a folder from your designer packed with logo files in formats you have never heard of. AI, EPS, SVG, PNG, JPG, PDF… which one should you actually use? And for what?
If you are a small business owner getting your brand identity for the first time, this guide is for you. We will break down the best file format for logo delivery, what each format does, and when to use it. No jargon, no fluff, just practical answers.
Why Designers Deliver Multiple Logo File Formats
Your logo will live in many places: a printed flyer, your website header, an Instagram profile picture, a t-shirt, a vehicle wrap. Each of these uses needs a slightly different file. That is why a proper logo package contains several versions of the same logo.
Logo files fall into two big families:
- Vector files (AI, EPS, SVG, PDF): made of mathematical paths. They scale to any size without losing quality. Perfect for printing and editing.
- Raster files (PNG, JPG): made of pixels. They have a fixed resolution and become blurry if enlarged too much. Perfect for web and social media.
The Main Logo File Formats, One by One
AI (Adobe Illustrator)
The AI file is the master file your designer creates the logo in. It is fully editable in Adobe Illustrator and contains every layer, color and path.
- Use it for: archiving the original. Send it to printers or other designers if they need to make changes.
- Do not use it for: putting on your website, emailing to a journalist, or uploading to Instagram. Most people cannot open it.
EPS (Encapsulated PostScript)
EPS is a vector format that has been the print industry standard for decades. It is more universal than AI because it can be opened by many design and print programs.
- Use it for: sending your logo to print shops, sign makers, embroiderers, or merchandise producers.
- Do not use it for: websites or social media.
SVG (Scalable Vector Graphics)
SVG is the modern vector format built for the web. It stays sharp on any screen size, including high-resolution Retina and 4K displays, and the file size stays tiny.
- Use it for: your website logo, your favicon, email signatures that support it, and any digital application that needs crisp scaling.
- Do not use it for: uploading to platforms that do not accept it (most social networks still want PNG or JPG).
PNG (Portable Network Graphics)
PNG is the everyday hero of digital logos. It is a raster format that supports transparent backgrounds, which means your logo can sit cleanly on any colored background.
- Use it for: social media profile pictures, presentations, Word documents, blog posts, email signatures.
- Do not use it for: large format printing like banners or billboards. It will pixelate.
JPG / JPEG
JPG is a compressed raster format. It does not support transparency, so your logo will always have a solid background (usually white).
- Use it for: simple cases where transparency is not needed and file size matters, like attaching to an email or uploading to a platform that rejects PNG.
- Do not use it for: placing your logo on colored backgrounds. The white box around it will look unprofessional.
PDF (Portable Document Format)
A PDF can contain vector data, which makes it incredibly handy. Almost anyone can open a PDF, and it scales without quality loss when saved correctly.
- Use it for: sending your logo to non-designers (printers, partners, agencies) when you are not sure what software they use.
- Do not use it for: embedding directly on a website or social media.
Quick Reference: Which Logo File for Which Use?
| Use Case | Recommended Format | Why |
|---|---|---|
| Website header / favicon | SVG (fallback PNG) | Sharp on any screen, tiny file size |
| Social media profile | PNG | Transparent background, widely supported |
| Business cards, flyers | EPS or PDF | Vector, print-ready quality |
| Large signs, banners, vehicles | EPS or AI | Scales infinitely without quality loss |
| T-shirts, embroidery, merch | EPS or AI | Required by most production shops |
| Email signature | PNG | Lightweight, transparent, opens everywhere |
| PowerPoint / Word doc | PNG | Easy to insert, supports transparency |
| Master archive | AI | Original editable file |
What a Complete Logo Package Should Contain
When we deliver a logo at Pixeliris, we make sure clients have everything they will ever need, organized in clear folders. A proper logo package should include:
- Vector master files (AI and EPS) in full color, black, and white versions
- PDF versions for easy sharing with printers
- SVG for web use
- PNG with transparent background, in multiple sizes
- JPG for general purpose use
- Horizontal, vertical and icon variations of the logo
- Color codes (HEX, RGB, CMYK, Pantone) so anyone can match your brand colors
Common Mistakes to Avoid
- Sending a low-resolution JPG to a printer. The result will be blurry. Always send a vector file (EPS, AI or PDF) for print.
- Using a JPG on a colored website background. You will get an ugly white box around the logo. Use a transparent PNG or SVG instead.
- Losing the master AI file. If you ever need to tweak your logo, the AI file is gold. Back it up in cloud storage.
- Resizing a PNG up. It will become pixelated. Always start from the largest version available, or use the vector file.
FAQ
What is the best file format to send a logo?
It depends on the use. For print, send an EPS or PDF. For web and social media, send a PNG with a transparent background. For websites specifically, SVG is the best choice.
Is JPEG or PNG better for a logo?
PNG is almost always better for logos because it supports transparent backgrounds and preserves sharp edges. JPG compresses images and adds a solid background, which is rarely what you want for a logo.
Should logos be PNG or SVG?
Use SVG on your website whenever possible: it scales perfectly and loads fast. Use PNG on platforms that do not accept SVG, like most social networks, presentations and documents.
Can I open an AI or EPS file myself?
Usually not without professional design software. That is why your designer also gives you PDF, PNG and JPG versions: those open on any computer or phone.
Do I really need all these formats?
Yes. You may not use them all today, but the day a printer asks for an EPS or a developer asks for an SVG, you will be glad you have them. A proper logo package is a one-time investment that saves headaches for years.

The best file format for logo delivery is not a single format, it is the right combination of formats that covers every situation your business will face. A professional designer should always deliver a complete, well-organized logo package so you never have to come back asking for missing files.
