JPG to PNG Converter
Convert JPEG images to PNG format.
About This Tool
JPG to PNG Converter is a free browser-based tool that converts JPEG images to PNG format instantly, with no upload required. PNG uses lossless compression, which means your converted image retains every pixel of the original quality — no artifacts, no blurring. The tool is ideal for anyone who needs their image in a format that supports transparency or requires the highest visual fidelity.
Conversion runs entirely in your browser using the HTML5 Canvas API. Your images are never transmitted to any server, making this one of the most privacy-preserving image conversion tools available. The process typically completes in under a second for standard images, and a live preview lets you inspect the result before downloading.
JPG to PNG is most commonly used when preparing images for web graphics, logo design, UI assets, or print production workflows where lossless quality is required. If you need transparency support for an existing JPEG (e.g., a product photo with a white background you plan to remove in a design tool), converting to PNG first is the right first step.

JPG to PNG Converter — Complete Guide →FAQ
Is the conversion lossless?
Yes, converting to PNG preserves image quality since PNG uses lossless compression.
Are my images uploaded?
No, all processing happens in your browser using Canvas API. Images never leave your device.
When should I use PNG instead of JPG?
Use PNG for images with text, sharp lines, logos, illustrations, or transparent backgrounds. PNG preserves crisp edges better than JPG's lossy compression.
Will the file size increase?
PNG files are typically larger than JPG because PNG uses lossless compression. For photographic images with no need for transparency, JPG is usually preferred for web use.
Does the converter support large images?
Yes, the Canvas API can handle large images. Extremely large images (e.g., 8000×6000px) may take a moment to render depending on your device.
