Privacy
Like our Image Compressor, this conversion needs more processing power than a browser can efficiently provide, so it runs on our server. Your image is converted in memory and returned directly in the same request — never written to disk or stored.
Frequently asked questions
Is this JPG to PNG converter free?
Yes. You can convert unlimited images for free, with no sign-up required.
Will converting JPG to PNG add transparency to my image?
No. A JPG has no transparency data to begin with, so the converted PNG is fully opaque, just like the original. Converting to PNG only changes the file format — it's a useful step if you plan to add transparency afterward in an image editor.
Will the file size increase?
Usually yes. PNG is a lossless format, so it tends to produce larger files than JPG for photos, in exchange for no additional quality loss. If file size matters more than losslessness, our Image Compressor can shrink the result afterward.
Do you keep my uploaded or converted images?
No. Nothing is saved anywhere — your image exists only for the moment it takes to process the request, then it is gone.
