JPG to PNG Converter: Convert JPEG to PNG Instantly
📸 Live preview — Convert JPG to lossless PNG for crisp graphics.
Why Convert JPG to PNG?
PNG is a lossless image format that retains every pixel exactly as it was. Unlike JPEG, which uses compression that can create artifacts and blur sharp edges, PNG is ideal for images with text, logos, screenshots, line art, and graphics requiring transparency. By converting a JPEG to PNG, you ensure that your image will never degrade further, and you gain the ability to add an alpha channel (transparency) for overlays and designs.
Common use cases: converting a scanned document (JPEG) to PNG for archival; turning a JPEG logo into a transparent PNG for website headers; or preserving sharp edges in UI mockups. Our converter uses the HTML5 Canvas API to redraw the JPEG and export it as a lossless PNG. The result is a file that can be edited, scaled, and used in any design software without quality loss.
Note that PNG files are typically larger than JPEGs because they store more data. Use PNG when quality is paramount; use JPEG for photographs where small file size is more important. Our tool gives you the freedom to switch formats instantly, all within your browser — no uploads, no registration.

⚙️ How the Conversion Works
When you select a JPG file, we read it using the FileReader API, then create an HTML Image element. After the image loads, we draw it onto a canvas element using the Canvas API. The canvas is then exported as a PNG using canvas.toBlob() with MIME type 'image/png'. Since PNG is lossless, the output retains every pixel from the original. This process is done entirely in your browser's memory — no external servers involved.
For images with transparency (e.g., PNG with alpha channel), the canvas preserves the alpha layer. However, JPG does not support transparency, so the resulting PNG will have an opaque background. If you need true transparency, start with a PNG or add a mask separately. Our tool also shows file size comparison so you know how much space the PNG will take.

PNG is lossless, so it stores more data. Ideal for graphics where file size is less critical than quality.
No, JPEG doesn't store transparency information. You'd need to edit the PNG in an image editor to remove background.
Yes, all processing happens locally. Your images never leave your device.
