Frequently Asked Questions
Why convert JPG to PNG?
PNG is lossless, so it is ideal for graphics, text-heavy screenshots, and images that will be edited again. Photos usually stay smaller as JPG.
Will a JPG to PNG conversion improve quality?
No. Converting cannot restore detail already lost to JPG compression, but PNG preserves all remaining pixels without further loss.
Is my photo uploaded anywhere?
No. Conversion happens entirely in your browser. Your photo never leaves your device.
