JPG to PNG Converter
Convert JPGs to PNG for tools that require it. Runs entirely on your device.
Your files stay in this tab. There is no upload endpoint on this site.
Be clear about what this does and does not do
Converting JPG to PNG does not improve the image. JPEG compression permanently discards detail when the file is first saved; wrapping those same pixels in a lossless container preserves them, but cannot bring back anything that was already thrown away. If a JPG looks blocky or soft, the PNG will look identically blocky and soft, at several times the file size.
That said, there are three genuinely good reasons to make this conversion.
Three cases where PNG is the correct output
A tool demands it. Plenty of software accepts PNG only — some print-on-demand services, certain app-icon and favicon pipelines, various game engines and design tools. Compatibility is a real requirement even when it is not a technical one.
You are about to start editing. If the photo will go through several rounds of crop, retouch and save, working in PNG stops each save from compounding new JPEG artifacts. Convert once at the start, edit losslessly, export to JPEG at the end.
You need to add transparency. You cannot make a JPEG transparent, because the format has no alpha channel. Converting to PNG first gives you a file that can hold transparency, so a background-removal tool has somewhere to write the result.
Common questions
Do my files get uploaded to a server?
No. Every tool on this site runs entirely in your browser using the Canvas and WebAssembly APIs. There is no upload endpoint in the page — you can confirm this yourself by opening your browser's Network tab while you convert a file. Nothing leaves the tab, which also means the tools keep working if you go offline after the page loads.
Will this make my photo higher quality?
No. The detail JPEG discarded is unrecoverable. PNG only prevents further loss from this point forward.
Why did the file get so much bigger?
PNG is lossless and photographic detail compresses poorly without loss. A 5–15× increase is normal for a camera photo.
Does converting to PNG remove the background?
No. It creates a file format that is capable of storing transparency, but every pixel stays opaque until something actually erases the background.
