Why convert JPG to PNG?

The most common reason to convert JPG to PNG is to gain transparency support. JPG does not support an alpha (transparency) channel — backgrounds are always opaque. PNG supports full transparency, making it the right choice for logos, icons, stickers and any image that needs to sit on a coloured background without a white box around it.

PNG is also a lossless format, meaning no data is discarded during compression. Editing and re-saving a PNG never degrades quality, unlike JPG which loses detail every time it is resaved.

Frequently asked questions

Why convert JPG to PNG?
PNG supports transparency (alpha channel) while JPG does not. Converting to PNG is useful when you need a transparent background for a logo, icon or graphic. PNG is also lossless, so there is no additional quality loss on conversion from JPG, though the original JPG compression artefacts are preserved.
Does converting JPG to PNG improve quality?
No. JPG is a lossy format and compression artefacts are baked into the pixel data. Converting to PNG saves those pixels losslessly, but does not restore lost detail. The result looks identical to the JPG but is now in a lossless container.
Will the PNG file be larger than the JPG?
Yes, usually significantly larger. PNG uses lossless compression so photos typically produce 3–5x larger files than equivalent JPGs. For photographic images, JPG is the better format for sharing. PNG is best for logos, icons, screenshots and images with text.
Can I convert multiple JPG files to PNG at once?
Yes. Drag and drop up to 20 JPG files onto the drop zone. All files are converted simultaneously in your browser and you can download them individually or as a single ZIP file.
Are my images uploaded to a server?
No. This converter runs entirely in your browser using the Canvas API. Your images never leave your device and are never seen by any server.
What is the difference between JPG and JPEG?
Nothing — they are the same format. JPEG (Joint Photographic Experts Group) is the full name; JPG is the shortened extension used on older Windows systems that required 3-character extensions. Both .jpg and .jpeg files are identical.
