Why logos turn pixelated
A logo pixelates when it’s shown bigger than the pixels it’s made of. A PNG 200 pixels wide has 200 columns of color; stretched across a 2,000-pixel banner, every pixel becomes a 10 × 10 block. Software smooths the blocks into blur, which is why an enlarged logo looks soft rather than blocky — and JPEG compression makes it worse, adding fresh noise around the edges every time the file is re-saved.
No sharpening filter can add detail that isn’t in the file. What you can do is replace the pixels with shapes, which can be drawn at any size.
First, look for the original
The cleanest fix is the file the logo was designed in. Ask the designer or agency for the source — .ai, .eps, .pdf, or .svg — check old brand folders and email attachments, and look inside PDFs: letterheads and brochures often carry the logo as vector paths you can copy out. The logo vectorizing guide lists where else to look.
Rebuild it as a vector
No original? Rebuild it. Flat logos — a few colors, clean shapes — trace very well, even from a mediocre source.
- Upload the largest, least-compressed copy you can find. A PNG beats a JPG; the original upload beats a screenshot.
- Open Settings → Palette → Choose palette and slide Simplify Colors down to the logo’s real colors plus the background. Drag the blurry in-between shades along the edges onto the colors they belong to — this is what turns fuzzy edges into crisp ones.
- Click each swatch and type the brand’s hex value. Blur averages colors together; this puts them back exactly.
- Hide the background swatch, or switch on Remove background, if the logo should sit on any color.
- Under Advanced → Detail, turn on Refine curves to color edges, and Fit to lines & arcs if the logo is geometric.
- Click Apply changes and compare the result against the source in Outlines over original.
Rescue the details
- Specks along edges or in flat areas are JPEG noise. Raise Minimum area (Advanced → Small regions) until they merge away.
- Soft, rounded corners that should be sharp come from the blur in the source. With Fit to lines & arcs on, straight edges are refitted as true lines, which usually brings the corner back.
- Circles that aren’t quite round — the same setting refits them as arcs. Set Fit tolerance to Loose if a wobble survives.
- Thin lines breaking up means the source has too few pixels across them. Lower the minimum area, or find a bigger copy.
Export sharp files for every use
| Where it’s going | What to download |
|---|---|
| Website or app | SVG |
| Printer, sign maker, merchandise | PDF or EPS |
| Slides, documents, social media | PNG, rendered at 4× or 8× |
| Cutter or laser | SVG or DXF |
For the PNG, open Advanced → Output size, choose Scale, and pick 4× or 8×. It’s rendered from the vector, so a logo that started at 200 pixels wide comes out at 800 or 1,600 with clean edges. Keep the SVG or PDF as your master copy; you can render a new PNG at any size from it later.
What about AI upscalers?
AI upscalers predict extra pixels from patterns learned on millions of images, and for photos they can be remarkable. For logos they have two drawbacks. The result is still a raster with a fixed size, so the problem returns at the next size up. And the model invents detail: letterforms shift slightly, straight edges waver, colors drift.
A vector rebuild gives you exact edges and exact colors in a file that scales without limit — and it’s the format printers ask for anyway. Use an upscaler for a logo that contains a photograph; rebuild flat logos as vectors.
When the source is simply too small
Below a certain size, the details simply aren’t in the file. A tagline eight pixels tall is a smudge, and no tracer can recover the letters from it.
- Trace the parts that survive — usually the symbol and the main wordmark.
- Identify the typeface of the small text (tools such as WhatTheFont help) and set it again in a vector editor.
- If even the symbol is too crude, use the trace as a template and redraw over it.
