When JPG beats PNG
Screenshots and photos saved as PNG are often 5โ10ร heavier than they need to be: PNG is lossless, which is wasted on photographic content. Convert them to JPG and a 4 MB screenshot becomes a 400 KB attachment that mails, uploads and loads without complaints โ visually identical at 90% quality.
PNG transparency doesn't exist in JPG, so you choose here what it becomes โ white or black. Everything converts in your browser: batch as many as you like, nothing is uploaded, no daily limits.
Frequently asked questions
What quality should I use?
90% is visually identical for almost everything. Drop to 75โ80% for maximum savings on photos where small artifacts don't matter.
What happens to transparent areas?
JPG has no alpha channel, so transparent pixels are filled with the background color you pick โ white by default.
When should I keep PNG?
For graphics with sharp edges and few colors (logos, diagrams, UI icons) and whenever you need transparency โ JPG would blur edges and fill the background.
