JPG uses lossy compression. Saving it as PNG does not restore detail already lost, but gives you a widely supported lossless output format.
Choose your files, adjust the output options, and start converting. Each file is processed separately. Download individual results or a ZIP archive. This version processes still images and does not preserve animation, camera metadata, or original color profiles.
A few things you might wonder
Are my images uploaded?
No. The converter reads and processes files in your browser without sending them to a server. Download your results before closing the page.
Will the output look exactly the same?
PNG supports transparency, but may produce larger files. Conversion cannot recover detail lost in the original, and metadata is not preserved.
