Convert JPG to PNG without uploading it

JPG is the universal photo format that every device, website and printer accepts. PNG is a lossless format with transparency, ideal for screenshots, logos and graphics. Drop your files and get PNG copies in seconds, decoded and encoded on your own device.

Runs on your device No watermark No sign-up No limits

Why convert JPG to PNG? Because it opens everywhere and keeps photos small, while it keeps transparency and razor-sharp edges. The conversion happens in your browser: the JPG is decoded to pixels and those pixels are written out as PNG. No quality is lost on the way.

Useful when an app or form demands PNG. The file will be larger than the JPG, because PNG stores pixels losslessly.

How to convert JPG to PNG

Drop the JPG files. As many as you like. They are read straight from your disk, so there is no upload wait.
PNG is preselected. PNG is lossless and needs no quality setting.
Download. Grab each file, or all of them as a zip.
