What this tool is for
Converting JPG to PNG gives you a lossless file that survives repeated editing and saving, which JPG does not. It does not recover detail the original JPG already lost, and the file will usually be larger. Your images are processed by your own browser through the Canvas API. They are never uploaded, which means no queue, no size limit imposed by a server, and no copy of your photo sitting in someone else storage.
How to use it
- Drop in your JPG files.
- Convert.
- Download the PNG results.
Frequently asked questions
Will converting improve the quality?
No. Compression artefacts already in the JPG are copied faithfully. What you gain is a format that will not degrade further with each save.
