Need lossless quality or a transparent background? Converting JPG to PNG gives you both. PNG preserves every pixel without compression artifacts — essential for logos, screenshots, graphics with text, and images that need further editing. While PNG files are larger than JPG, the quality guarantee is worth it when precision matters. Note: converting to PNG doesn't add transparency — you'll need to remove the background separately (use our Background Remover tool). This converter processes everything in your browser for complete privacy.
Lossless, supports transparency. Larger file size.

Why Convert JPG to PNG
PNG gives you lossless quality and transparency support — essential for logos, screenshots, graphics with text, and any image destined for further editing. While PNG files are larger than JPG, every pixel is preserved exactly without compression artifacts. Note that converting from JPG to PNG won't restore quality lost during initial JPG compression — it preserves the current state without adding further degradation.
JPG vs PNG — Format Comparison
JPG is smaller but lossy; PNG is larger but lossless. Converting JPG→PNG is useful when you need to edit the image without further quality degradation, or when the target platform requires PNG format. Understanding these differences helps you pick the right format for each use case — web performance, editing workflows, print, or maximum compatibility.
Privacy-First Browser Conversion
This JPG to PNG converter processes your images entirely in your browser using the Canvas API and WebAssembly codecs. No files are uploaded to any server — your images never leave your device. This makes it safe for personal photos, business documents, and sensitive design assets. Since this conversion uses lossless encoding, the output preserves every pixel exactly as the input. There are no file-size limits, no daily quotas, and no watermarks added to your converted images.

Frequently Asked Questions
Does converting JPG to PNG improve quality?
No. Converting to PNG preserves the current quality without adding further compression, but it can't recover quality lost in the original JPG encoding.
Will the PNG have a transparent background?
No. The original JPG's white/colored background is preserved. To get transparency, use a background removal tool first, then save as PNG.
Why is my PNG file much larger than the JPG?
PNG uses lossless compression while JPG uses lossy compression. The PNG stores every pixel exactly, which requires more data. This is normal and expected.
