About JPG ↔ PNG Converter
Different image formats have different strengths: JPG is best for photos with smooth color gradients, PNG is better for graphics with sharp edges and transparency, and WebP often outperforms both at the cost of slightly less universal support. This converter switches images between JPG, PNG, and WebP formats, preserving quality and handling transparency channels correctly during the conversion.
Common use cases include converting screenshots from the default PNG to JPG for smaller file sizes, swapping a JPG to PNG when you need to add transparency, and producing WebP variants for modern browsers to improve page load speed. Batch processing lets you convert multiple images at once, useful when migrating a folder of legacy assets to a newer format.
How to Use
Select one or more image files (JPG, PNG, or WebP).
Choose the target format you want to convert to.
For JPEG/WebP, adjust the quality slider.
Click 'Convert' and download the converted files.
Frequently Asked Questions
When should I use PNG vs JPG?
Use PNG for images that need transparency or have sharp edges (logos, screenshots, graphics). Use JPG for photographs and complex images where smaller file size matters more than pixel-perfect quality.
What about WebP?
WebP is a modern format by Google that offers better compression than both JPG and PNG. It supports both lossy and lossless compression, plus transparency. Most modern browsers support it.
What happens to transparency when converting PNG to JPG?
JPEG doesn't support transparency. When converting PNG to JPG, transparent areas are filled with white. If you need to keep transparency, convert to PNG or WebP instead.
Can I convert multiple images at once?
Yes! Select multiple files at once and they will all be converted in batch. You can download them individually or all at once.
