Best File Format for Logos: PNG vs SVG vs WEBP

A logo has a harder job than almost any other image. The same mark has to look sharp in a 32-pixel browser tab, a website header, a slide projected on a wall, an email signature, a business card and possibly a printed banner. The file format you choose decides whether it survives all of those cleanly or turns up blurry, jagged or sitting in an ugly white box.

The short answer is that most businesses need the same logo in two or three formats, each used where it works best. Here's how each format behaves and where it belongs.

Raster vs vector: the difference that matters

Formats fall into two families.

Raster formats (PNG, JPG, WEBP) store a fixed grid of coloured pixels. A 500×200 PNG has exactly 100,000 pixels, no more. Display it larger than that and the software has to invent extra pixels, which is why enlarged raster logos look soft or blocky.

Vector formats (SVG, as well as AI, EPS and PDF) store shapes as mathematical instructions: "a curve from here to here, filled with this green". Software redraws those shapes at whatever size is needed, so a vector logo is perfectly sharp at 16 pixels and at 16 metres.

If your logo was designed in Illustrator, Affinity Designer, Figma or Inkscape, a vector master file exists somewhere. Get it from your designer and keep it safe, because every other version should be exported from it.

SVG: the best choice for websites

SVG is a vector format that every modern browser displays natively. For a logo in your site header, navigation or footer it has clear advantages:

• •Sharp on every screen, including high-density phone and laptop displays, with no need for 2× or 3× versions.
• •Tiny file size: a typical logo is 3–30 KB, often smaller than an equivalent PNG.
• •Editable: colours can be changed with CSS, which is handy for a white version on dark backgrounds.

SVG's weaknesses are compatibility outside the browser and complexity. Many email clients, social media platforms, Microsoft Office versions and online form uploaders won't accept SVG. Logos containing photographic elements or complex gradients also don't translate well to vector and can produce huge SVG files.

PNG: the universal fallback with transparency

PNG is a raster format with lossless compression and full transparency support. It's the format to use whenever SVG isn't accepted: social media profile pictures, email signatures, Word and PowerPoint documents, marketplace listings, and anywhere else you need the logo to sit on a coloured background without a white box around it.

Because PNG is raster, export it larger than you need. A useful rule is to export at least twice the largest size it will be displayed at. For general use, a version around 1000–2000px wide covers most situations, and you can scale it down as needed.

WEBP: smaller files for the web

WEBP supports transparency like PNG but compresses much more efficiently, often 25–35% smaller at the same visual quality. It's a good choice when you're serving a raster logo on a website and want to save bandwidth, and all current browsers support it.

Outside the browser, support is patchier. Some older design programs, email clients and upload forms still reject WEBP files, so it's best treated as a web-delivery format rather than the version you send to other people.

JPG: avoid it for logos

JPG has two problems for logos. It doesn't support transparency, so the logo always comes with a solid rectangle behind it. Its compression is also designed for photographs and creates fuzzy halos and blotches around the hard edges and flat colours that logos are made of. The only time a JPG logo makes sense is when a system accepts nothing else, and even then a high quality setting (90+) is essential.

Which format to use where

Common mistakes

Using a screenshot of the logo. Screenshots capture the logo at screen resolution, usually with background pixels around it. They look fine on screen but fall apart in print.

Enlarging a small PNG. If the only file you have is a 200px PNG from an old website, enlarging it won't create detail. Track down the vector original or have the logo redrawn.

A JPG with a white background on a coloured page. The white rectangle is impossible to hide. Export a PNG with transparency instead, or remove the background from the image you have.

SVGs containing embedded images. Some programs export an "SVG" that simply wraps a PNG inside. It looks like a vector file but behaves like a raster one. If an SVG logo looks blurry when enlarged, this is usually why.

A simple logo kit

For most small businesses, this set covers everything:

1. 1The vector master (SVG, plus AI, EPS or PDF from your designer).
2. 2A transparent PNG of the full-colour logo, around 2000px wide.
3. 3A transparent PNG of a white or single-colour version for dark backgrounds.
4. 4A square version of the icon or initials, for social media profiles and favicons.

If you only have a logo with a solid background, BG Bueno's background remover can produce a transparent PNG from it in your browser. For a logo that will be used at large sizes, though, nothing beats getting a proper vector file.
