Logos need to look sharp at every size — from tiny favicons to large billboard print. If you only have a small raster logo (JPG or PNG), upscaling it correctly can produce a larger version suitable for presentations, print, and high-resolution displays.
Why Logo Upscaling Is Challenging
Logos contain sharp edges, flat colour areas, and fine text — all of which show upscaling artefacts more obviously than photographs. A photo upscaled 3× looks soft but acceptable. A logo upscaled 3× may show jagged edges, blurry text, and colour bleeding. The best solution for logos is always to use a vector format (SVG, EPS, AI) — these scale infinitely without any quality loss.
How to Upscale a Raster Logo Free
Upload your logo PNG or JPG to imgresizr.com. Open the Enlarge tool and enter your target dimensions. Apply strong sharpening after upscaling — logos benefit more from sharpening than photographs. If the logo has a white background, converting to PNG preserves clean edges. Download as PNG for best quality.
Logo Size Guide
| Use Case | Recommended Size |
|---|---|
| Website header logo | 200–400 px wide |
| Email signature | 150–300 px wide |
| Business card (print) | At least 1200 px wide at 300 DPI |
| Conference banner (print) | Minimum 3000 px wide |
The Better Solution: Get the Vector Original
- Ask your designer for the SVG or EPS master file
- Vector logos can be exported to any pixel size without upscaling artefacts
- If no vector exists, recreate the logo as SVG using a vector tool — worth the one-time investment
