How it works
Choose your JPG images or drop them on this page. You can add several at once.
Each photo is decoded in this browser tab, turned upright if the camera saved it sideways, and saved as a PNG.
Download each PNG, or all of them in one ZIP file.
Questions
Are my images uploaded anywhere?
No. The work happens inside this browser tab, so your images never leave your device and no server sees them. Closing the tab clears them from memory.
Why is the PNG larger than the JPG?
PNG keeps every pixel exactly, so a photo usually takes more space as a PNG. Converting does not bring back detail the JPG already dropped, and it does not make the background transparent.
What are the limits?
Up to 100 images at a time. Each can be up to 80 MB and 50 million pixels, and the copies are at most 16,384 pixels wide or high. Animated PNG and WebP files are not converted, because only their first frame would be kept.
The same file engine is in the UFO apps for Android and Windows.
