PNG Upscaler
Enlarge PNG images while preserving full transparency (alpha channel). This upscaler uses bicubic resampling to produce the smoothest possible result when scaling up — without introducing white backgrounds or artifacts.

💡 Pro Tips & Best Practices
✓
Start with the highest-quality original file you have — upscaling cannot invent detail that does not exist.
✓
Doubling the size (2x) produces acceptable results; 4x or more will show visible softening.
✓
For POD products, check the platform's minimum resolution requirements before submitting.
✓
After upscaling, check at 100% zoom for any softening or blurring in fine details.
✓
For Etsy digital downloads, upscale to at least 3000px on the longest side for versatility.
✓
PNG Upscaler Pro (batch version) handles multiple files and custom size targets simultaneously.
✓
Transparency is fully preserved — no white or black background is added during the process.
