FAQ
Does this upload my files?
No. Everything runs locally in your browser. Your files never leave your device.
Can I use it offline?
Yes. After the page loads, disconnect from the internet and convert as normal.
Will PNG add transparency?
No. JPG has no transparency, so the PNG will be opaque unless you edit it afterwards.
Why is the PNG bigger?
PNG is lossless and often larger than JPG, especially for photos. PNG is great for edits and graphics.
Will this improve image quality?
It will not restore detail lost to JPG compression, but it prevents further loss when editing and re-exporting.
