JPG to PNG Converter Online Free
Some tools, editors, and websites ask for a PNG when all you have is a JPG: a design app that prefers lossless images, a document that needs sharp graphics, or a project that only accepts PNG uploads. This free JPG to PNG converter changes your photo into a PNG file in seconds, right in your browser, at exactly the same width and height as the original. Because PNG is lossless, every pixel of your JPG is kept exactly as it is, with no further quality lost in the conversion. There is nothing to install, no account to create, and no sign-up, and your photo is never uploaded to a server, never stored anywhere, and never seen by anyone else, which matters for personal photos. The conversion uses the canvas built into your browser: your JPG is drawn onto a canvas and saved as a PNG, so the whole job happens on your own device. You can preview the result before you download it, and compare the original and converted file sizes side by side.
One JPG at a time (.jpg or .jpeg). It will be converted to PNG at the same size.

Privacy: your image never leaves your browser. Conversion runs entirely on your device.
How to Use
- Add your JPG. Click the drop zone and choose one JPG or JPEG file, or drag it straight from your computer into the box. Its name and size appear below the box so you can check you picked the right photo.
- Click Convert to PNG. The tool loads your image, draws it onto a canvas at its full original size, and saves that canvas as a PNG. The progress bar shows the conversion as it happens.
- Check the preview and sizes. The converted PNG appears as a preview below the button, and the result panel shows the dimensions in pixels plus the original JPG size and the new PNG size, so you can see the difference before downloading.
- Download the PNG. Click Download .png to save the converted image. It is saved with the same name as your JPG, but with a .png ending, so it is easy to find next to the original.
Worked Example
Suppose you have a JPG photo that is 1200 pixels wide and 800 pixels tall, saved from a camera, and a design tool asks for a PNG. Add the JPG and click Convert to PNG. The expected result is a PNG that is still exactly 1200 by 800 pixels, because the conversion keeps the dimensions of the original and only changes the file format. The picture itself looks the same, since PNG is lossless and keeps every pixel as it was, but the file is usually larger than the JPG: a JPG of about 180 KB can easily become a PNG of 700 KB or more, because JPG compression throws away fine detail to save space while PNG stores every pixel exactly. That size increase is normal and expected. A smaller photo, such as 800 by 600 pixels, converts in the same way, keeping its 800 by 600 size and gaining a larger file in return for the lossless format.
Why Convert JPG to PNG in Your Browser?
Most online image converters ask you to upload your photo to a remote server, where you have no control over how long it is kept or who can see it. That is a real risk for personal photos, family pictures, or work images that are not meant to be shared. This tool takes the opposite approach: the conversion runs on your own device, inside your browser, using the canvas your browser already provides, and the photo never travels over the internet at all. There is no server involved, no queue to wait in, and no account that links the image to you. A very large photo may take a moment longer on an older phone, but for everyday photos the conversion finishes almost instantly.
Tips for a Good Conversion
Remember that converting a JPG to PNG cannot improve the quality of the original photo: JPG compression already removed some fine detail when the photo was saved, and no conversion can bring that detail back. The PNG simply preserves what is left, perfectly, which is exactly what you want when you need to edit the image again without losing more quality. Expect the PNG to be larger than the JPG, so check the sizes shown in the result panel before you send the file anywhere. A JPG also has no transparency, so do not expect see-through areas in the converted PNG: the background stays solid, exactly as it was in the original photo.
Frequently Asked Questions
Is it really free to convert JPG to PNG here?
Yes. Converting a JPG to PNG on this page is completely free, with no account, no sign-up and no watermark. You can convert as many images as you like, and every PNG you download belongs to you.
Are my images uploaded to a server?
No. Your JPG never leaves your browser. The conversion runs entirely on your device using the canvas built into your browser, so your photo is never uploaded, stored or seen by anyone else.
Will converting JPG to PNG change the quality?
No. PNG is a lossless format, so the converted image keeps exactly the pixels of the JPG you uploaded, at the same width and height. The conversion cannot restore detail that the JPG compression already removed, but it loses nothing further.
Why is the PNG larger than the original JPG?
JPG uses lossy compression that throws away fine detail to make a small file, while PNG stores every pixel exactly, so the same picture needs more space as a PNG. A detailed photo can easily become several times larger, which is the price of the lossless format.
Will the converted PNG have a transparent background?
No. A JPG has no transparency at all, so there is no transparent area for the PNG to keep. The converted PNG will have the same solid background as the original JPG, with no see-through parts.
