SVG vs PNG for Logos — Which to Choose
You downloaded a logo, dropped it into your site header, admired it, and a week later noticed it looks slightly blurry on a good phone screen, as if shot through fogged glass. Or the opposite: the logo is crisp, but the page loads forever because the "image" weighs two megabytes. Both outcomes follow from a single choice made on autopilot: SVG or PNG. On screen the two look identical, yet they are built so differently that mixing them up plants a problem which surfaces later.
SVG is vector: the logo is described by formulas (lines, curves, fills), so it scales without quality loss and recolors easily. PNG is raster: a fixed grid of pixels, but every program understands it, including old email and office suites. The right mental model is simpler: a master and its print. Keep the logo in SVG and generate a PNG of the needed size from it.
What's inside the file
To choose deliberately, grasp one thing: SVG and PNG store fundamentally different things. One stores an instruction for how to draw, the other stores the already‑finished drawing. Everything else follows from that difference.
SVG (Scalable Vector Graphics) is a text XML file with a mathematical description of shapes: point coordinates, Bézier curves, fills, strokes. When a browser or editor opens an SVG, it computes the pixels anew, right then, for the exact screen size. So a line stays perfectly crisp at 16 pixels or 1600: the instruction runs at any scale.
PNG (Portable Network Graphics) works the opposite way. It is raster: the image is a fixed grid of pixels, each with its recorded color. The grid is set once, at save time, and never changes. As long as you show the PNG at its native size or smaller, everything's sharp. But enlarge it past the baked‑in size and the software has to invent missing pixels, guessing the color between neighbors. Hence the "mush" on a good screen: a 200-pixel logo stretched to 400, with nowhere to get the missing data.
From this pair, instruction versus print, grow all the practical differences that make the choice matter.
What this means in practice
Since SVG stores an instruction, it loses nothing when scaled: every size is computed from scratch. Since PNG stores a finished grid, it can only lose when enlarged. That's the first and main consequence, and the rest trail behind it.
An instruction describes shape compactly: "circle radius 45, fill green" takes a few dozen bytes, while an honest pixel grid of the same logo weighs many times more. So a simple SVG logo is usually lighter than its own PNG. The instruction is also editable: color lives in a separate fill value you can change without touching the shape (how that's done in a couple of clicks — see how to change a logo's color). In PNG, color is baked into every pixel, and recoloring means repainting.
But the print has its own strength the instruction can't match. PNG is understood by literally any program, from an ancient mail client to an office suite, because raster came first and became the common denominator. PNG also honestly stores what a vector can't capture in a formula: photographic gradients, shadows, complex textures. Where SVG would build a heavy contraption, PNG simply records finished pixels.
The cleanest way to see it all at once is a table: here the properties simply coexist, so comparing them row by row is handy.
| Criterion | SVG | PNG |
|---|---|---|
| Type | Vector (formulas) | Raster (pixels) |
| Scaling | Lossless, any size | Lossless down only; up means blur |
| File size | Usually smaller for simple logos | Larger, especially at high resolution |
| Recoloring | Change fill values | Needs an editor, repaint pixels |
| Transparent background | Yes, natively | Yes, via alpha channel |
| Support in email and messengers | Not always correct | Everywhere |
Editing in Figma /Illustrator | Full: shape, nodes, color | Limited: one flat picture, no separate objects |
| Animation | Possible (SMIL, CSS) | No, needs GIF or video |
| Print shop | No limits | Fails above native resolution |
The table shows SVG winning almost every row. Which raises the logical question: why keep PNG at all if vector is objectively better? The answer hides in the one row that reads "not always", meaning support.
Where SVG wins
Everywhere a browser shows the logo, vector becomes the obvious pick, for exactly the reason we started with. On a website SVG weighs less and stays crisp on any screen, Retina included: separate @2x versions never need wiring up. In editors — Figma, Sketch, Illustrator — vector can be split apart, recolored, its nodes nudged; for layout work that is the whole point of the format. In print you can't work without vector: printing enlarges the image to banner size, and only SVG survives it losslessly. Logo animation (a smooth fade, a rotation, a color shift) lives right inside the SVG via CSS, with no separate video.
The common denominator is simple: if the image is shown by a program that reads the instruction, hand it the instruction. Trouble starts where no such program exists.
Where PNG is needed
And it doesn't exist in the most conservative corners of the digital world. Email is the main one: some clients, especially corporate ones on Outlook
, don't render SVG at all, and the recipient sees blank space instead of a logo. Presentations in PowerPoint and Google Slides handle vector hit‑or‑miss and lose some effects. Social networks, when you upload an avatar or cover, still demand raster: the platform re‑compresses the file into its own format. Finally, complex logos with photorealistic gradients and textures balloon in SVG until raster turns out both lighter and safer.
There's also a technical case where PNG remains the only option. If the logo is embedded into a finished image, say an OG preview card for social networks, everything around it is already raster, and inserting a vector makes no sense.
Notice: in all these cases we take PNG because the environment can't do vector. That is the key to the whole confusion, and to the typical mistakes as well.
Three mistakes that grow from one misunderstanding
Almost every format problem comes down to one thing: the print gets used as a master, or the other way around. Hence three classic slips.
The most common mistake — dropping a 512-pixel PNG logo into the header and stretching it with CSS. On a regular screen this is invisible, while on Retina the logo goes "floaty". If an SVG of the logo exists, always use it on the web, whatever the layout size.
The reverse slip — putting SVG into a newsletter or presentation. Some mail clients show nothing, and the recipient gets blank space instead of the logo. For emails, slides and office documents use PNG: precisely the case where the print beats the instruction.
If the only file is a PNG 200×200 and you need a 2000×2000 banner, stretching kills quality: pixels multiply without recomputation. The only way out is to find the logo in SVG or convert it to vector; how that's done and where the pitfalls are — see how to convert a logo to vector.
All three vanish if you keep the hierarchy in mind: SVG is the master, PNG is derived from it. And if so, conversion should run one way.
How to get PNG from SVG, and why not the reverse
The right direction runs from instruction to print. From an SVG you can render a PNG of any size at any moment and stay crisp. In our catalog both buttons — SVG and PNG — are ready on every logo page, so no manual conversion is needed. And if you need a PNG of an unusual size, open the SVG in Figma or right in the browser and export at the needed resolution: that gives you a sharp image made for the task. A full walk‑through of five methods sits in «How to convert SVG to PNG and back».
The reverse path, making SVG from PNG, is exactly the compromise to avoid. The software doesn't know the original curves and can only auto‑trace the outlines (this is called tracing) or offer to redraw the logo by hand. The first ruins complex shapes, the second costs money. That's why the rule "keep the master in vector" exists: recovering it from raster is far pricier than generating raster from vector. If all you have is a PNG, the rescue is in «How to convert a logo to vector».
What to do when the PNG replaced the master
A separate case shows up more often than you'd expect: the vector existed but got lost. The designer delivered the project, moved on, and the company folder holds only PNGs for the website. Formally the logo exists; in practice the brand has lost its master and now hits a resolution ceiling with every new task.
The cure starts with searching, and only then with tracing. Check in order: the email archive with the designer, the company cloud, the press kit on your own site (the vector was often published there for journalists), and the files at the print shop that produced the business cards. The vector turns up in one of those places roughly half the time, and that beats any redraw on cost. While you're at it, store the recovered SVG somewhere the next change of contractor can't carry it away.
SVG and PNG aren't the only formats
Worth keeping in mind that these two don't exhaust the logo world. Nearby live the vector AI, EPS and PDF, used by professional designers and print shops. There's also the raster JPG, which unlike PNG can't do transparency and so barely suits logos, yet is irreplaceable for photos. When each is appropriate and how they differ from our pair is laid out in «What format should a logo be in».
What to choose in the end
Back to that blurry logo from the start. Its trouble came from using a print as a master: a finished pixel grid was stretched where an instruction was needed. Keep this hierarchy in mind and the choice stops being a guess. SVG is the master, from which a PNG of any size is born. PNG is the derivative for environments where vector won't open: email, presentations, some social networks, and logos with complex effects. In doubt, take SVG: from it you can always get a PNG, while the road back is far costlier.
Every logo in the Trace Logo's catalog comes in both SVG and PNG at once: master and print in one place, free to download.
