Frequently asked questions
Will converting to PNG improve my photo's quality?
No — compression artifacts already in the JPG are preserved exactly. PNG only guarantees nothing further is lost from here on.
Why is the PNG bigger than my JPG?
PNG compresses losslessly, which suits graphics, not photographs. A photo's natural noise defeats PNG compression, so files grow — that is normal.
When does JPG to PNG make sense?
When a system requires PNG input, when you need a lossless working copy before editing, or when you plan to add transparency in an editor afterwards.
About this tool
Sometimes a workflow simply requires PNG: an app that only accepts it, an editor that wants a lossless intermediate, or a document pipeline standardised on one format. This converter re-encodes JPG files as PNG locally — drop the files, download the results. Be aware of what conversion can and cannot do: PNG stores the pixels losslessly from this point on, but detail already lost to JPEG compression does not come back, and the file will typically grow because photographs are what JPEG is good at. For shrinking files, go the other way — JPG or WebP.
