When should you convert JPG to PNG?
JPG is a lossy format built for photographs. It is fantastic for small file sizes, but every save discards a little detail and it cannot carry transparency.
PNG is lossless. Once your image is a PNG, further edits and re-saves preserve every pixel — making it the right choice for logos, screenshots, product shots on a transparent background, UI mockups, illustrations and anything with crisp edges or text.
Advantages of PNG
- Lossless quality — no compression artefacts introduced.
- Alpha transparency support (needed for logos and UI assets).
- Sharper text and edges compared to a re-saved JPG.
- Universally supported across every modern operating system, browser and design tool.
Privacy-first browser processing
Most online converters upload each file to a remote server, process it there, and hand you a download link. A copy of your file exists on infrastructure you don't control. This JPG to PNG Converter never uploads anything — the entire conversion runs inside your browser using the built-in Canvas API, so your photos, screenshots and client assets stay on your device.
