Drop a JPG and it is re-encoded as a lossless PNG on your device — never sent to a server.
Drop a JPG and it is re-encoded as a lossless PNG on your device — never sent to a server.
Convert JPG images to PNG in your browser. PNG is lossless and universally accepted — the format to reach for when an upload form refuses your JPG, when you're about to edit an image repeatedly, or when an app demands PNG specifically. The conversion happens entirely on your device: drop the JPG, download the PNG, and nothing touches a server in between. Free, no signup, no watermark.
How it works
Drag a JPG onto the page. It opens in the GhostImage studio with Convert → PNG pre-selected.
The image is re-encoded as a lossless PNG in your browser — no upload, no queue.
Save it — or keep working: resize, crop, or strip metadata in the same tab.
No — the conversion runs in your browser. Nothing is sent anywhere.
No — converting can't restore detail JPG compression already discarded. It stops any further loss: PNG re-saves are lossless.
PNG is lossless, so it stores photos less efficiently than JPG. That's the trade: bigger file, zero generational loss, transparency support.
The pixel data converts; if you want EXIF (location, camera, timestamps) gone, run Strip Metadata in the same studio — worth doing before sharing anything.
Yes — PNG to JPG is the same Convert step with the JPG target, usually to shrink a file 5–10×.
Every GhostImage tool runs entirely in your browser. Your file is never uploaded — there's no upload endpoint to send it to.
