Frequently Asked Questions
What is the difference between JPG and PNG?
JPG (JPEG) uses lossy compression, which means some image data is discarded to reduce file size. PNG uses lossless compression, preserving all image data perfectly. PNG also supports transparency (alpha channel), while JPG does not. PNG is ideal for graphics, logos, screenshots, and images requiring transparency, while JPG is better for photographs where smaller file size is preferred.
Does converting JPG to PNG add transparency?
Converting a JPG to PNG changes the format to one that supports transparency, but it does not automatically make any part of the image transparent. The converted PNG will look identical to the original JPG. However, you can now edit it in image editors and add transparency where needed, since PNG supports alpha channels.
Will the PNG file be larger than the original JPG?
Yes, typically the PNG file will be larger than the JPG. This is because PNG uses lossless compression while JPG uses lossy compression. The trade-off is that PNG preserves perfect image quality with no compression artifacts. For photographs, PNG files can be 2-5x larger than their JPG equivalents.
Is my data safe when using this tool?
Absolutely. All conversion happens entirely in your browser using the HTML5 Canvas API. Your images are never uploaded to any server. The processing is done locally on your device using JavaScript, so your files remain completely private and secure.
