The formats
JPG and PNG at a glance
What is a JPG file?
JPG (also written JPEG) is the most common format for photos. Its lossy compression discards detail your eye is unlikely to notice, which keeps files small, and you can trade size for quality when you save. It has no transparency, and saving the same image again and again slowly adds visible artifacts. It opens in practically everything: browsers, phones, cameras, Windows Photos, macOS Preview, Word and Google Docs, every photo editor, and every website that accepts uploads.
What is a PNG file?
PNG is a lossless image format, so it keeps every pixel exactly as it was saved. It supports transparent backgrounds, which makes it the usual choice for logos, screenshots, and graphics with sharp edges or text. A photo saved as PNG is often several times larger than the same photo as a JPG. It opens in every web browser, Windows Photos, macOS Preview, iPhone and Android galleries, and editors like Photoshop, GIMP, and Figma.
Good to know
What changes when you convert JPG to PNG
- PNG is lossless, so the image won't lose any more quality, but it can't restore detail that JPG compression already removed. Expect a bigger file.
- Metadata such as the camera model, date, and GPS location isn't copied to the new file, so you don't share your location by accident.
- Very large images, around 100 megapixels or more, can exceed what the browser allows, especially on phones.
FAQ
Questions, answered
Is this JPG to PNG converter free?
Yes. It's completely free, with no sign-up, no watermark, and no limit on how many files you convert. It costs Ethical Tube nothing to run, because the conversion happens on your own device rather than on a server.
Are my files uploaded anywhere?
No. The conversion runs inside your browser with the browser's built-in image codecs plus small WebAssembly encoders, so your files never leave your device. Once the page has loaded, it even works offline.
Does converting JPG to PNG lose quality?
No. PNG is lossless, so the converted image has exactly the pixels of the JPG. It can't undo compression that the JPG already has, though, and the file may be bigger.
Can I convert several JPG files at once?
Yes. Add as many as you like. They're converted one after another, and you can download each PNG file as soon as it's ready or all of them in one ZIP file.
Does it work on iPhone, Android, Mac, and Windows?
Yes. It works in Chrome, Edge, Firefox, and Safari, on computers, iPhones, and Android phones.
What can open a PNG file?
Every web browser, Windows Photos, macOS Preview, iPhone and Android galleries, and editors like Photoshop, GIMP, and Figma.
Is there a file size limit?
There's no upload limit because nothing is uploaded. The practical limit is your device's memory: everyday files are fine, and most computers handle images up to about 100 megapixels.
