Why Your Logo Looks Blurry and How to Fix It — Every Cause Explained
The logo looked perfect in the mockup — and turned to mush on the website. Or on the projector. Or on business cards from the print shop. A blurry logo is the thing visitors notice instantly: it makes a brand look cheap before anyone reads a single word. Good news: there are only six causes, and every one is fixable.
Nine times out of ten a logo is blurry because a small raster file was stretched to a larger display size. The cure is either SVG (vectors can't blur, period) or a PNG at least 2× the display size — because of retina screens.
Cause 1. A small PNG was stretched
The classic. The file is 200×200, the site slot is 400 px wide. The browser has to invent the missing pixels — interpolate — and edges swim.
Check: compare the file's real pixel size with its display size. Display bigger than file = diagnosis confirmed.
Fix: get a larger source. "Lossless upscaling" of a finished PNG doesn't exist; AI upscalers help photos but usually leave artifacts on sharp‑edged logos.
Cause 2. Retina screens need twice the pixels
Even with a perfect size match — a 200 px PNG in a 200 px slot — it still looks soft on iPhones and most modern laptops. These screens pack 2–3 physical pixels into each CSS pixel: a 200×200 slot actually renders 400×400 or 600×600 dots.
Fix: the 2x rule. The file should be at least double the display size: 200 px slot → 400 px PNG. Or SVG, which doesn't care about pixel density at all.
Cause 3. It's a JPG
JPG compresses with loss and handles hard edges — which logos are made of — especially badly. The "dirt" around letters and outlines is compression artifacts, often mistaken for blur.
Fix: re‑saving a JPG won't help; the loss already happened. You need the PNG or SVG source. We covered why JPG is wrong for logos in our format comparison.
Cause 4. The platform recompressed it
You uploaded a great file, but the social network, marketplace or CMS resized it and applied its own JPG compression. Avatars and covers suffer most.
Fix: upload exactly the size the platform asks for (so its resizer stays off), with quality to spare. For avatars — a square of 400×400+ with no fine detail: at 40 px, thin lines vanish in any format.
Cause 5. Fractional sizes and CSS transforms
Layout can blur a logo too: an element with fractional width (199.5 px from flexbox), scaling via transform: scale(), or an image stretched by width: 100%.
Fix: give the image integer dimensions — or use SVG, which shrugs these off. If an SVG still looks soft at small sizes, check whether filter or opacity is forcing the browser to pre‑rasterize it.
Cause 6. Print: 72 dpi instead of 300
Great on screen, mush on business cards. Screen resolution (72–96 dpi) isn't enough for print, which needs 300 dpi. A 1000×1000 px PNG prints sharply at only ~8.5 cm.
Fix: send vectors to print (EPS, PDF, SVG — whatever the shop accepts). No vector? Then raster at 300 pixels per inch of physical size.
Cheat sheet
| Symptom | Cause | Fix |
|---|---|---|
| Blurry everywhere on site | stretched small PNG | SVG or 2× PNG |
| Sharp on monitor, soft on iPhone | retina | 2x rule or SVG |
| "Dirt" around letters | JPG artifacts | find PNG/SVG source |
| Blurry only on one platform | platform recompression | upload exact size |
| Blurry only in print | 72 dpi | vector or 300 dpi |
Notice the pattern? Almost every row of that table is cured by the word "SVG". Vectors don't depend on slot size, screen density or print dpi. If a platform accepts SVG — always choose it, and the entire class of "blurry logo" problems disappears.
Step‑by‑step diagnosis in five minutes
When the blur is there but the cause isn't obvious, walk the chain:
- Open the file itself, separately from the site (drag into a browser, view at 100%). File sharp? The problem is in how it's displayed — go to step 3. File already blurry — step 2.
- The file is blurry. Check its properties: extension (JPG?), pixel dimensions (smaller than needed?). Hunt for a better source — no processing will save this file.
- File sharp, site blurry. Open DevTools (right‑click the logo → Inspect) and compare two numbers: the file's real size and its displayed size. Displayed larger than the file → causes 1–2. Sizes match but phones blur → retina, cause 2.
- Blur in one place only (a social network, a marketplace, an email) → the platform recompressed it, cause 4. Compare your upload with a re‑downloaded copy — the difference will show.
This sequence covers practically every case and, more importantly, shows where to fix: the file, the layout, or the upload settings.
Can AI upscalers save a blurry logo?
Upscalers (Topaz, Real‑ESRGAN, editor built‑ins) work miracles on photos, so the temptation is real. The result usually disappoints: on crisp edges and typography, neural networks paint wavy contours, round off letter corners and "invent" details. The correct path for a logo is different — not restoring pixels but returning to vector: find the SVG original or redraw — see how to vectorize a logo. An upscaler is acceptable as a stopgap for a secondary image — not for the mark that represents the brand.
The special case: blur in video and presentations
A corner logo in a video or on a slide blurs for its own reasons:
- Video compression. YouTube and social platforms compress aggressively, and a small logo suffers first. Cure: a larger logo in frame, a contrasting background, and — for intros — vector animation instead of a static image (see animated logos).
- Projectors at foreign resolutions. A 1024×768 projector will stretch your neat deck. Insert SVG into slides (PowerPoint supports it) or double‑size PNGs.
- Zoom/screen sharing compresses the stream — a logo always looks worse on a share than locally. That's the channel's limit, not your file's.
In short
Blur is always a shortage of pixels somewhere: too few in the file, eaten by compression, or not dense enough for retina or print. The fix is one of two things: a vector — or a raster with a 2× margin.
