AI vs EPS vs SVG vs PDF: Which Logo File Do You Need?

For most businesses, the best setup is to keep an AI file as your master, send EPS or PDF to printers, embroiderers and sign makers, and use SVG for websites and many apps. All four can hold a vector logo that scales to any size, but only if the artwork inside was built as vector. A file ending in .pdf or .eps can still contain a flat, pixelated image.

What each format actually is

AI (Adobe Illustrator)

AI is the native file of Adobe Illustrator. It keeps everything a designer built: separate layers, editable shapes, live text, color swatches and effects. That makes it the best working file. If someone needs to change a color, resize one element or rebuild a layout, an AI file is what they want.

The downside is that AI is a proprietary format. Many printers and sign shops can open it, but not every program or non-designer can. Think of it as your master copy rather than the file you send to everyone.

EPS (Encapsulated PostScript)

EPS is an older vector format that became a standard way to exchange logos between programs. Print shops, embroidery digitizers, promotional product companies and sign makers have accepted it for decades, so it opens in a huge range of professional software.

Its limits are age-related. EPS does not handle modern transparency and effects well, and it does not preview nicely on a regular computer. It is a reliable hand-off format, not a friendly one.

SVG (Scalable Vector Graphics)

SVG is an open vector format built on text-based code. Web browsers display it directly, so it stays sharp on any screen size and is usually very small in file size. Many design tools, website builders and hobby cutting machines also accept it.

SVG is the right choice for websites, apps, and digital use. For traditional print production, some shops prefer PDF or EPS, though plenty accept SVG too. Always ask.

PDF (Portable Document Format)

PDF is the most flexible of the four because almost everyone can open it. A PDF can hold vector artwork, raster images or both. A PDF exported from Illustrator with the vector artwork intact works well for printers. A PDF made by dropping a screenshot of your logo into a document does not, even though it looks identical on screen.

Quick comparison

Format	Best for	Strength	Watch out for
AI	Master file, designer edits	Keeps layers, editable text and colors	Needs Illustrator or compatible software to edit
EPS	Printers, embroidery, signs, promo items	Accepted by a wide range of production software	Older format, limited transparency, no easy preview
SVG	Websites, apps, digital use, some cutters	Sharp at any size, lightweight, opens in browsers	Some print workflows prefer PDF or EPS
PDF	Sharing proofs, sending to print	Opens almost anywhere	May contain a flat image instead of vector

Which one should you send for each job?

• Commercial printing (flyers, banners, packaging): a vector PDF or EPS is the usual request. If the printer asks for AI, send that.
• Screen printing: vector PDF, EPS or AI, so colors can be separated cleanly. See preparing a logo for screen printing for the details.
• Embroidery: send a vector file (EPS, AI or PDF) as a reference so the digitizer can see clean shapes. The stitch file itself is a separate format made from your artwork.
• Signs and vinyl cutting: EPS, AI, PDF or SVG, depending on the shop’s software. Ask before sending.
• Website and social media: SVG for the site itself, and a transparent PNG where SVG is not accepted.
• Giving a designer your logo: AI if you have it, otherwise EPS or a vector PDF.
• Everyday documents and slides: a high-resolution transparent PNG is usually the simplest option.

Not sure which one a specific shop wants? Ask them for their file requirements. Printers are used to the question, and it prevents a round of back and forth later.

The biggest mistake: trusting the file extension

The extension tells you the container, not the quality. People often discover this when a logo looks fuzzy on a banner despite being a PDF. If the vector artwork was never created, the format changes nothing. You cannot turn a low-resolution image into a vector by renaming it or saving it as another type.

Here are quick ways to check what you have:

1. Open the file in a vector program such as Illustrator or Inkscape.
2. Zoom in to a very high level on the edge of a letter.
3. If the edge stays crisp, it is probably vector. If it turns blocky or blurry, it is raster.
4. Click on the logo. Vector artwork shows editable paths and anchor points, while a raster image shows a single box with an X or a bounding rectangle.

Our guide on how to check whether your logo is really vector goes through this in more depth, and what a vector file is and why printers ask for one explains the idea behind it.

Other mistakes that cause trouble

• Live text and missing fonts. If your logo uses a font the recipient does not have, the lettering can change. Text should be converted to outlines (shapes) in the files you send out. Keep an editable version in your master.
• Embedded or linked images. A vector file that links to an external picture can show a blank spot when moved to another computer.
• Wrong color mode. Print files are usually CMYK or spot colors, while screens use RGB. A file in the wrong mode can shift colors.
• Too many colors for the process. Gradients, shadows and fine details can be a problem for screen printing, embroidery and vinyl, even in a perfect vector file.
• Sending only one version. A single color file for everything makes life harder than it needs to be.

If a vector file still prints wrong, why a vector logo may still print incorrectly covers the usual causes.

A sensible set of logo files to keep

You do not need a dozen formats, just a small, organized folder:

1. AI master file with live text and layers.
2. EPS and vector PDF with text converted to outlines, for printers and production shops.
3. SVG for web and digital use.
4. Transparent PNG at high resolution for documents, slides and social media.
5. One-color and reversed (white) versions of the logo, in the same formats.

When doing it yourself stops working

Exporting between these formats is easy when you already have a real vector master. The trouble starts when you do not. If all you have is a JPEG from an old email, a photo of a sign, a screenshot or a faded shirt, there is nothing for the software to convert. Auto-trace tools can produce a vector outline from a picture, but they often leave wobbly edges, extra points and rounded corners, especially on small text and fine details.

That is the point where having the design properly redrawn makes sense. RedrawLogo recreates logos and designs from whatever image you have, including photos, screenshots, scans and printed items like shirts, signs, stickers and business cards. The design is redrawn as clean vector artwork, and you receive files such as AI, EPS, SVG, PDF and a high-resolution transparent PNG that work with any printer, embroiderer, sign maker or designer. This applies to designs you own or have the right to use.

If you want to understand the difference between tracing methods first, read manual vector tracing vs automatic vectorization.

The bottom line

Pick the format for the job: AI to edit, EPS or PDF to print, SVG to publish online. Make sure the artwork inside is genuinely vector, and keep a small organized set of files so you never have to hunt for them again. If you only have an image of your logo, you can send it through the RedrawLogo order page and get the full set of files built from it.

Frequently asked questions

Which logo file format is best overall?

There is no single best format. Keep an AI file as your editable master, use EPS or vector PDF for printers and sign makers, and use SVG for websites. A transparent PNG is handy for everyday documents and social media.

Is a PDF a vector file?

Only sometimes. A PDF can contain vector artwork, raster images or a mix of both. If the logo inside is a pasted picture, it will look pixelated when enlarged, even though the file is a PDF.

Can I convert a JPEG or PNG logo to EPS or SVG by changing the file type?

No. Saving or renaming a file does not create vector shapes. The design has to be traced or redrawn as vector artwork first, and then it can be exported to EPS, SVG, PDF or AI.

Do printers prefer EPS or PDF?

It varies by shop and by print method. Many accept either, and some ask specifically for AI. The safest move is to ask the printer which file types and settings they want before you send anything.

Should I use SVG or PNG on my website?

SVG is usually a good choice for logos on a website because it stays sharp at any size and loads as a small file. Use a transparent PNG in places that do not accept SVG, such as some email programs or social platforms.

What if I only have a photo or screenshot of my logo?

You can have the design redrawn as clean vector artwork from that image, as long as you own it or have the right to use it. RedrawLogo does this and delivers files like AI, EPS, SVG, PDF and transparent PNG.
