When to use PNG instead of JPG
PNG is lossless, so it keeps sharp edges on text, logos, screenshots and line art, and it supports transparency. JPG compresses photographs far smaller but softens fine detail each time it is saved. Converting a JPG to PNG stops further quality loss, though it cannot restore detail already lost, and the PNG file is usually larger.
How this converter works
Your browser decodes the JPG, redraws it on an in-memory canvas and encodes a PNG, all on your device. Files never leave your computer, which makes it safe for ID documents and private photos. Drop several files to convert them in one go.
Frequently asked questions
Does converting JPG to PNG improve quality?
No, it preserves the current quality and prevents further loss on future saves.
Why is the PNG bigger than the JPG?
PNG stores every pixel losslessly; photos compress poorly this way.
Is there a file size limit?
Only your device's memory. Images up to 50 MB work on most laptops and phones.
