JPG to PNG Converter

Converting a JPG to PNG creates a lossless-format copy of your photo: from this point forward, the file can be re-saved any number of times without introducing new compression artifacts, which JPG does on every re-save. People convert JPG to PNG when a design tool, image editor, or upload form specifically requires PNG input, when they want a stable master copy to edit further, or when they're preparing a graphic for a workflow that assumes PNG. This tool converts JPG to PNG directly in your browser, no software to install and no file uploaded to a server.

How to use

1. Upload your JPG. Drag a JPG file onto the drop zone or click to browse. Only JPG/JPEG files are accepted for this converter.
2. Click Convert to PNG. The image is redrawn onto a canvas and re-encoded as PNG entirely in your browser. There's no quality slider to set, PNG encoding is lossless, so there's no quality trade-off to choose.
3. Download your PNG. Click Save to download the converted file, or Save As to pick the filename and location yourself.

JPG vs PNG

JPG uses lossy compression: it discards some image data on every save to achieve much smaller file sizes, which makes it the standard format for photographs and other images with smooth gradients and continuous tone. PNG uses lossless compression: it keeps every pixel exactly as encoded and supports a transparency (alpha) channel, which makes it the standard format for screenshots, logos, line art, and any graphic that needs a transparent background. Converting a file from one format to the other doesn't change what kind of image it is underneath, it changes how that image data is stored. Two things this conversion specifically does not do: it does not restore detail or sharpness that JPG compression already discarded, and it does not add transparency to an image that didn't have any, a JPG has no alpha channel to begin with, so the converted PNG comes out fully opaque.

Tips for best results

• Expect a larger file. A PNG version of a photographic JPG is typically several times larger than the source file, because lossless compression can't match JPG's lossy compression ratio on photographic content. If file size matters, keep the original JPG for delivery and use the PNG only where PNG is actually required.
• Use this to stop compounding JPG generations. If you plan to open, edit, and re-save an image repeatedly, converting to PNG first means each edit-and-save cycle stays lossless from that point on, instead of re-compressing a JPG and losing a little more detail every time.
• It won't add a transparent background. If you need to remove a background and make it transparent, this conversion alone won't do that, you need a background-removal or masking step before the transparency will actually appear in the PNG.
• Compress afterward if size matters. Since the resulting PNG is usually larger than the source JPG, run it through the image compressor afterward if you need to bring the file size back down for web or email use.

Why use PixMidas

• 100% private. The conversion redraws your image on a canvas and re-encodes it entirely in your browser. Your JPG is never uploaded to any server.
• Honest about what conversion can and can't do. We won't tell you converting to PNG improves quality or adds transparency, it does neither. It gives you a lossless-format copy, nothing more.
• No account needed. Free and instant. Works in any modern browser, no installation required.

Frequently asked questions

Does converting JPG to PNG improve image quality?

No. Any detail or sharpness lost when the original photo was saved as JPG is already gone from the pixel data, and no file format conversion can bring it back. Converting to PNG simply stops any further quality loss from this point forward, since PNG won't re-compress and discard data the way saving as JPG again would. If you need a genuinely higher-quality source, you need the original uncompressed photo, not a format conversion.

Will the PNG file be larger than my original JPG?

Usually, yes, often several times larger. JPG's lossy compression is very effective on photographic content, while PNG's lossless compression has to preserve every pixel exactly, which costs more space for the same image. This is normal and expected, not a sign anything went wrong.

Does converting from JPG to PNG add transparency to my image?

No. JPG has no alpha channel, so there's no transparency information for the converter to carry over. The resulting PNG is fully opaque, pixel for pixel, matching the original JPG. To get a transparent background, you'd need a separate background-removal step, converting the file format alone doesn't do that.

Is the resulting PNG lossless from here on?

Yes, with one caveat. The PNG format itself is lossless, so once you have the converted file, opening and re-saving it as PNG again won't introduce any new compression artifacts. What it can't do is remove the compression artifacts that were already baked into the pixel data by the original JPG encoding, those are permanent. Think of it as: no further damage, but no undo either.

Why would I convert JPG to PNG if it doesn't improve quality?

Because plenty of tools and workflows specifically require or prefer PNG input, some design software, some upload forms, and some image-editing pipelines that assume a lossless source. Converting also gives you a stable base for further edits: every future save as PNG stays lossless, whereas repeatedly opening and re-saving a JPG compounds quality loss with each cycle.

Is my photo uploaded to a server?

No. The entire conversion runs on your device using your browser's Canvas API. Your JPG is read locally, redrawn, and re-encoded as PNG without ever being sent anywhere, safe for personal photos, client work, or anything else you'd rather not upload.
