logomovoVector vs Raster Logos: Which File Should You Use?
Learn when to use vector and raster logo files, what an SVG really contains, and how to hand off files for web, social and print.
Your logo may look sharp in a browser tab and blurry on a printed sign. The difference often comes down to whether the file contains shapes or a fixed grid of pixels.
What is a vector logo?
A vector file describes shapes with coordinates, paths and fills. The same paths can be rendered at different sizes without enlarging a fixed pixel grid. SVG is a common vector format for the web. The W3C SVG specification also allows an SVG to contain embedded raster images, so an SVG extension alone does not prove that every part of a logo is editable vector artwork.
What is a raster logo?
A raster file records pixels at a particular width and height. PNG, JPEG and WebP are common raster formats. A 500 × 500 pixel PNG can work well for a small social profile image. Enlarging that same file for a large sign asks software to invent additional pixels, which can soften edges and lettering. A sufficiently large raster can still be suitable for a particular output size; ask the printer for its requirements.
Which file should you use?
| Job | Useful starting file | Check before delivery |
|---|---|---|
| Website header | SVG | Does it contain real paths, and do fonts or external images load correctly? |
| Social profile | Square PNG | Is the mark readable after the platform crops it? |
| Presentation or document | SVG or high-resolution PNG | Does the receiving app render it correctly? |
| Signage or packaging | Printer-approved vector PDF, SVG or source file | Does the vendor accept the format, fonts and colors? |
| Photo-heavy composition | High-resolution raster | Are the pixel dimensions sufficient for the intended output? |
The MDN image format guide recommends SVG for graphics that must draw accurately at different sizes and PNG over JPEG when precise edges or transparency matter. JPEG can introduce visible artifacts around sharp logo edges and does not support transparency.
Does converting PNG to SVG make it vector?
Changing a filename or placing a PNG inside an SVG does not turn its pixels into editable paths. Automatic tracing can create paths, but inspect small lettering, corners, gaps and curves before treating the result as a production master. If the original artwork is available, exporting from that source is usually more reliable than tracing a tiny screenshot.
A practical handoff check
- Keep the original editable source file and an exported SVG or vector PDF.
- Export transparent PNGs for places that require raster images.
- Open each file in its intended app or browser. Zooming in can reveal obvious pixelation, but also inspect the file structure because a raster embedded in an SVG may appear smooth at modest zoom levels.
- Preview the mark at both small and large sizes. Thin details that technically scale may still become unreadable when reduced.
- Ask the print vendor for its required format rather than assuming every vendor accepts the same file.
The goal is a small set of files that you can actually use, not a long list of extensions. If you only have a low-resolution image, retain it as a reference and recreate or commission a clean master before a large print job.
