This free JPG to PNG converter turns your .jpg images into .png files. JPG is universal and lossy. Every re-save degrades it a little further, so it is a poor place to keep an image you will edit again.
Because browsers cannot write PNG, this one runs on our server: the file is converted in memory and sent straight back. It is never written to disk, never logged and never stored.
How to convert JPG to PNG
- Drop your JPG files onto the box above, or click it to choose from your computer. Up to 20 at once.
- The conversion starts as soon as the file is read — there is nothing to configure.
- Download each converted file, or pick them up one by one from the list.
What changes when you convert JPG to PNG
PNG is lossless, but it cannot restore what JPG already discarded. The output will be larger than the input and no sharper — you are preserving the current state, not recovering the original.
JPG and PNG compared
| JPG | PNG | |
|---|---|---|
| Full name | JPEG — Joint Photographic Experts Group | Portable Network Graphics |
| Extension | .jpg, .jpeg | .png |
| MIME type | image/jpeg | image/png |
| Compression | Lossy | Lossless |
| Transparency | No | Yes |
JPG: Lossy compression tuned for photographs, supported by every device made in the last thirty years. No transparency, and repeated re-saving degrades the image, so keep an original.
PNG: Lossless compression with full alpha transparency. The safe default for screenshots, logos, diagrams and anything with sharp edges or text, at the cost of larger files than JPG for photographs.
Frequently asked questions
How do I convert JPG to PNG?
Drop your .jpg file onto the box on this page and the .png file is ready to download in a second or two. There is no signup, no email, no watermark and no file limit beyond about 4 MB per upload — larger images are re-encoded smaller in your browser first, and the page says so when that happens.
Is this JPG to PNG converter free?
Yes, completely, with no account, no trial and no watermark on the output. We are a consultancy and these tools exist because we needed them ourselves; there is nothing to buy on this page.
Are my files uploaded anywhere?
This one has to run on our server, because browsers cannot write PNG. The file is converted in memory and returned immediately — it is never written to disk, never logged and never stored. If that is not acceptable for your file, use a desktop tool instead.
Will converting to PNG reduce the quality?
PNG is lossless, but it cannot restore what JPG already discarded. The output will be larger than the input and no sharper — you are preserving the current state, not recovering the original.
Can I convert several JPG files at once?
Yes, up to 20 files in one go. Drop them all onto the box together and each one appears in the results list with its own download button.
