How to Resize PNGs?

📤

1. Select File

Upload your PNG image. Our tool supports transparent backgrounds and high-res files.

📏

2. Adjust Size

Enter your target width or height. The aspect ratio stays locked by default for consistency.

3. Save Result

Click download. Your resized PNG is generated instantly with alpha-channel transparency preserved.

Preserve PNG Transparency

Unlike standard image editors that might add a white or black background when resizing, our PNG Resizer is built to respect the alpha channel. Whether you are resizing a logo, an icon, or a graphic with complex transparency, the background remains invisible and clean.

No Quality Loss Resampling

When scaling PNGs, maintaining edges is crucial. We use high-quality interpolation algorithms that prevent the "blurring" effect often seen in basic tools. This ensures your PNGs look sharp on retina displays and professional layouts alike.

Frequently Asked Questions

Will my PNG lose transparency?

No. Our tool is specifically optimized for the PNG format. Any transparent pixels in your original image will remain transparent in the resized version.

Is there a file size limit for PNGs?

We support large PNG files up to 50MB. Because the processing happens on your own computer, it is limited only by your device's memory.

Can I resize PNG to a specific KB size?

PNG is a lossless format, so it doesn't support quality-based compression like JPG. To reduce KB size, we recommend using our "Compress PNG" tool after resizing.
