The PNG format is essential for graphic design, web development, and digital art because it supports lossless compression and true transparency.

How to Convert JPG to PNG & Adjust Pixels
- Upload your Image: Drag and drop your JPG or WEBP image into the converter. The workspace will load instantly.
- Set Exact Pixel Dimensions: Use the width and height controllers on the left to resize your image. Keep "Maintain Aspect Ratio" checked so your picture doesn't stretch or warp.
- Set Target KB Size (Optional): PNGs are naturally large files because they are lossless. If you need the file to be under a certain size limit (e.g., 500KB), type it into the Target Size box. Our tool will smartly and proportionally scale down the physical dimensions of the image during download to hit your target size.
- Download Instantly: Click the download button to save your formatted PNG directly to your computer.
