Convert JPG to PNG online for free with our browser-based image converter. PNG format preserves image quality with lossless compression and supports transparency, making it ideal for logos, graphics, screenshots, and any image you plan to edit later. No upload, no signup, no watermark — your photos stay on your device.
Drag and drop a .jpg or .jpeg image into the upload zone, or click to browse. The tool accepts standard JPEG files up to whatever size your browser can hold in memory.
The image is decoded onto an HTML5 Canvas element and re-encoded as a PNG file. There's nothing to configure — the tool produces a maximum-quality lossless PNG every time.
Click the download button to save your converted PNG. The file name is automatically updated with a .png extension.
JPG uses lossy compression, which means every save degrades quality slightly. PNG uses lossless compression, so editing, resaving, and re-exporting your image keeps every pixel exactly as it was. That's why designers, illustrators, and developers prefer PNG for source files.
PNG also supports an alpha (transparency) channel that JPG can't. If you're preparing a logo for a website, a UI mockup, or a graphic that needs to overlay other content, PNG is the right format.
This converter works in any modern browser on Windows, Mac, Linux, ChromeOS, iPhone, and Android. Because conversion is local, you can convert hundreds of files back-to-back without hitting any server-imposed rate limit.
