JPG to PNG Converter
Convert JPG images to PNG free, right in your browser.
Quick answer: To convert JPG to PNG free, use a converter that re-encodes the actual pixel data — renaming the file extension does not change the format. This tool decodes your JPG and re-encodes it as a real PNG directly in your browser, with no upload, signup, size cap or watermark.
This tool converts JPG images to real PNG files by re-encoding the pixel data — not by renaming the extension. Everything happens locally in your browser: your image is never uploaded to any server.
JPG is the universal photo format — small files, no transparency, slight quality loss on every save. PNG is lossless and supports transparency, which makes it the standard for logos and artwork.
How it works
- Drop a JPG file (or several) onto the upload area, or tap to choose from your device.
- Each image is decoded and re-encoded as PNG in your browser using the canvas engine.
- Preview the result and download each file, all without your image leaving your computer.
Good to know
- Very large images (over ~50 megapixels) can exceed browser memory limits.
- Animated images are converted using their first frame only.
Frequently asked questions
Is this JPG to PNG converter really free?
Yes — completely free, with no signup, no daily limit, no watermark and no file cap. Because the conversion runs in your own browser, it costs us almost nothing to offer, so there is no catch.
Is my image uploaded to your server?
No. The file is read and converted entirely inside your browser using the HTML5 canvas engine. It never leaves your device, which also makes this faster than upload-based converters.
Does converting JPG to PNG improve quality?
No — PNG stores the image losslessly from that point on, but it cannot recover detail the JPG already discarded. If you need a crisp version of a blurry JPG logo, it needs to be redrawn as vector art, not converted.
Will my PNG have a transparent background?
Not automatically. JPG has no transparency, so the converted PNG keeps the original background. Removing a background is a separate editing step.
