JPG ↔ PNG Converter
Convert JPG to PNG, or PNG to JPG, instantly in your browser. Convert one image, or switch to Bulk mode to convert an entire folder at once and download every result as a single ZIP file. Nothing is uploaded.
JPG vs PNG
JPG uses lossy compression and no transparency, making it ideal for photos. PNG is lossless and supports transparency, making it better for logos, graphics, and images with sharp edges or text.
What happens when converting PNG to JPG
Since JPG has no alpha channel, any transparent areas in a PNG are filled with white before conversion. Keep this in mind if your PNG relies on transparency.
Bulk mode
Bulk mode applies the same conversion direction to every selected image and bundles all the converted files into one ZIP download — useful when you need to convert a whole batch of photos or graphics in one step.
Common Mistakes to Avoid
Converting a transparent PNG to JPG and losing transparency
Solution:
JPG cannot represent transparency — converting fills transparent areas with a solid background color (white by default). If you need transparency, keep the file as PNG or WebP.
Expecting PNG conversion to shrink file size
Solution:
PNG is lossless, so converting a photo from JPG to PNG usually increases file size rather than reducing it.
Frequently Asked Questions
