Logo File Format Guide: SVG, PNG, EPS, AI, and PDF Compared

Your designer just handed you a folder with your new logo in six different file formats. You need one for the website header, one for business cards, and one for the embroidery shop printing your team hoodies. Which file do you grab?

The wrong logo file format means blurry headers, pixelated print runs, or a merch vendor sending your file back with a polite but firm "we can't use this." The right format means your logo looks sharp everywhere it appears — from a 16px favicon to a 10-foot trade show banner.

Here is exactly which format to use and when.

Vector vs. Raster: The Fundamental Split

Every logo file format falls into one of two camps, and understanding this distinction eliminates most of the confusion.

Vector formats (SVG, EPS, AI, PDF) store your logo as mathematical instructions — points, curves, and colors. Scale them to any size and they stay perfectly crisp. A vector logo on a billboard looks identical to one on a business card.

Raster formats (PNG, JPG, WebP) store your logo as a grid of colored pixels. Scale them up and the pixels become visible. A 200px PNG stretched to fill a poster looks like a mosaic viewed from too close.

The rule: Always maintain a vector master file. Generate raster versions from it as needed for specific contexts. Never go the other direction — you cannot meaningfully reconstruct vectors from raster images.

The Five Logo File Formats Explained

SVG — The Web Standard

SVG (Scalable Vector Graphics) is an open XML-based vector format that browsers render natively. It is the best logo file format for anything displayed on a screen.

• Scales infinitely without quality loss
• Tiny file sizes — most logos are under 5 KB as SVG
• CSS and JavaScript controllable — change colors on hover, animate elements, adapt to dark mode
• Text-based — search engines can read SVG content
• License: Open W3C standard. No licensing restrictions.

Best for: Website headers, favicons (via inline SVG), email signatures, app icons, responsive design.

Limitation: Not every print vendor accepts SVG. Some legacy design tools have incomplete SVG support.

PNG — The Universal Raster

PNG gives you a raster logo with transparency support and lossless compression. When a platform demands a raster image, PNG is your first choice.

• Transparency support — your logo floats cleanly over any background
• Lossless compression — no quality degradation from saving
• Universal compatibility — every platform, app, and service accepts PNG
• License: Open standard, no restrictions.

Best for: Social media profiles, platform uploads that reject SVG, presentation decks, document embedding.

Limitation: File size grows with resolution. A 4000px PNG logo can hit 500 KB+. Always resize logos to the exact dimensions needed rather than uploading oversized files. For a deeper comparison, see our SVG vs. PNG breakdown.

EPS — The Print Industry Workhorse

EPS (Encapsulated PostScript) is a legacy vector format that remains the lingua franca of professional printing. If you are sending a logo to a print shop, they almost certainly want EPS.

• Universal print compatibility — accepted by virtually every commercial printer
• Vector precision — maintains sharpness at any print size
• Color profile support — handles CMYK for accurate print color reproduction
• License: Adobe-originated format, openly documented. No licensing fees to use EPS files.

Best for: Business cards, brochures, trade show materials, packaging, any commercial print job.

Limitation: Not web-friendly. Browsers do not render EPS. Large file sizes compared to SVG. Modern alternatives (PDF, AI) are gradually replacing it, but print shops still ask for it. Read our full EPS explainer for the complete picture.

AI — The Design Source File

AI (Adobe Illustrator) is the native format of Adobe Illustrator, the industry-standard vector design tool. This is typically where your logo was born.

• Full editability — layers, effects, typography, and color swatches preserved
• The design master — your designer's working file with everything intact
• License: Proprietary Adobe format. Requires Adobe Illustrator (subscription: $22.99/mo) or Affinity Designer 2 ($69.99 one-time) to fully edit. Free viewers like Inkscape (GPL v2) can open AI files with some feature loss.

Best for: Future logo edits, design agency handoffs, brand asset archives.

Limitation: Useless for direct deployment — you never put an AI file on a website or send it to a printer without converting it first. It is a source file, not a delivery file.

PDF — The Versatile Middle Ground

PDF can contain both vector and raster data, making it the Swiss Army knife of logo formats. A well-exported PDF preserves vector sharpness while being viewable on any device.

• Universal viewability — every operating system has a PDF reader
• Vector precision when exported correctly from a vector source
• Print-ready — supports CMYK, bleed marks, and press-quality output
• License: Originally Adobe proprietary, now an open ISO standard (ISO 32000). No licensing restrictions.

Best for: Brand guidelines documents, client presentations, print submissions when EPS is not required, archival.

Limitation: Not all PDFs are vector — a PDF exported from a raster source is just a raster image in a PDF wrapper. Verify your PDF contains actual vector paths before using it for large-format printing.

Best Practices for Logo File Management

Keep a brand asset folder with your logo in all five formats, organized by color variant (full color, black, white, monochrome) and orientation (horizontal, stacked, icon-only). A typical folder looks like:

/logo
  /svg      — web deployment
  /png      — social and digital (export at 1x, 2x, 3x)
  /eps      — print production
  /ai       — source files for future edits
  /pdf      — presentations and guidelines

Export PNGs at exact sizes rather than relying on platforms to resize. A 5000px PNG resized by Instagram's compressor looks worse than a 1080px PNG you controlled. Resize your logos to the precise dimensions before uploading.

Never use JPG for logos. JPG compression creates artifacts around sharp edges and solid colors — exactly the characteristics of most logos. The file size savings over PNG are minimal for simple graphics, and the quality loss is visible. This goes double for logos with text.

Embed fonts or convert to outlines before exporting EPS or PDF. If the recipient does not have your logo's font installed, the text renders in a fallback font. Converting text to vector outlines eliminates this risk entirely.

FAQ

What is the best logo file format for websites?

SVG is the best logo file format for web use. It scales to any screen size without quality loss, typically weighs under 5 KB, and can be styled with CSS for dark mode or hover effects. Use PNG as a fallback where SVG is not supported.

Can I convert a PNG logo to a vector format?

Not meaningfully through automated conversion. Tracing tools (like Inkscape's bitmap trace or Adobe's Image Trace) produce approximations that rarely match the original design's precision. Always start from the original vector source file (AI, SVG, or EPS) and export to other formats from there.

Why do print shops ask for EPS instead of SVG?

Print workflows were built on PostScript technology decades before SVG existed. EPS integrates directly with professional prepress software, supports CMYK color profiles, and handles print-specific features like spot colors and bleed areas that SVG was not designed for.

What logo format do I need for T-shirt printing?

Screen printers and embroidery shops need vector files — EPS or AI. Vector outlines define the exact stencil shapes for screen separation and the stitch paths for embroidery machines. A raster PNG, no matter how high-resolution, cannot provide this information.

Is PDF a vector or raster format?

PDF can be either. A PDF exported from Illustrator or another vector tool contains vector paths and scales perfectly. A PDF created by "printing" a raster image is just a raster file inside a PDF container. Open the PDF in Illustrator — if you can select individual paths and anchor points, it is vector.

Should I use WebP or AVIF for my logo on the web?

Stick with SVG for logos on the web. WebP and AVIF are raster formats designed for photographs where lossy compression artifacts blend into complex image detail. Logos have sharp edges and flat colors where compression artifacts are highly visible. SVG gives you perfect quality at a smaller file size.
