JPG to PNG
To convert JPG to PNG, add one or more photos, convert them and download them individually or as a ZIP. PNG is lossless, so it survives repeated editing without further damage, but it cannot restore detail the JPG already lost and is often three to five times larger. There is no transparency to carry over. Nothing is uploaded.

How to use JPG to PNG
- 1Add one or more JPG files.
- 2Press Convert.
- 3Download the PNG files individually or as a ZIP.
How it works
The JPEG is decoded to raw pixels and re-encoded as PNG, which stores those pixels losslessly. Nothing more is lost in the conversion — but nothing that JPEG already discarded comes back either. Compression artefacts baked into the original stay in the PNG.
The practical reason to convert is editing. Every time a JPEG is saved it is re-compressed, so repeated edits accumulate damage. PNG can be opened and saved indefinitely with no further loss, which makes it the better working format.
Expect the PNG to be substantially larger — often three to five times the JPEG — because lossless storage of photographic detail simply takes more space.
Images are decoded by the browser, redrawn on a canvas and re-encoded on your own machine. Nothing is uploaded, so there is no waiting on a queue and no copy of your photos anywhere else.
Tips and common mistakes
- Convert to PNG when you are going to edit an image several times. PNG can be saved again and again without adding damage.
- Keep sharing JPGs as JPGs. For a photo that is only being sent or posted, PNG just makes the file several times bigger.
- Converting does not make a background transparent. The PNG is fully opaque, exactly like the JPG it came from.
- If a site or app insists on PNG, this is the quickest way to satisfy it without changing how the picture looks.
