About JPG files
JPG (also written JPEG) is the format almost every camera and phone photo is saved in. It opens everywhere and keeps photos small, but it can’t hold transparency.
How to convert JPG to PNG
- Drop your JPG on the box above, or click it to choose it.
- Click “→ PNG”.
- Your file downloads. MunchFiles checks that the result opens correctly before it hands it to you.
What to expect
Lossless and keeps transparency.
- Usually a larger file.
- Photo metadata (camera, location) is not copied.
Questions
Are my files uploaded anywhere?
No. MunchFiles converts files inside your web browser, on your own device. The file is never sent to a server, so nobody else can see it.
Is it free?
Yes. Basic file conversions are free, with no account and no watermark. MunchFiles Pro is an optional one-time purchase (no subscription) that keeps a copy of MunchFiles on your device, working offline, with power tools for batches, shrinking images and PDF pages.
Does it work on my phone?
Yes. It works in any modern browser on a phone, tablet or computer. There is nothing to install.
How big can the file be?
MunchFiles has no upload limit, because nothing is uploaded. The only limit is what your browser can draw: images up to about 268 megapixels (or 32,767 pixels on a side).
