JPG to PNG Converter

JPG vs PNG: what’s the difference?

JPG (JPEG) is the lossy format built for photographs since 1992: it compresses well but discards a little detail every time it is saved, has no transparency and no animation, and in return opens on every device and in every program. PNG is lossless, so every pixel is kept exactly; it supports full alpha transparency and is ideal for logos, screenshots and graphics with text. A photo saved as PNG, however, is usually several times larger than the same photo as JPG.

When to convert JPG to PNG

Converting JPG to PNG does not improve quality — detail removed by JPEG compression stays lost — and the file usually gets larger. It makes sense when you will edit the image repeatedly without further loss, or when a tool only accepts PNG. The resulting PNG is fully opaque; transparency can be added later in an editor.

How to use

1. 1Drop images in any format your browser can open (JPG, PNG, WebP, GIF, SVG, AVIF…).
2. 2Choose the output format: WebP, PNG, JPEG or AVIF (when your browser supports encoding it).
3. 3Adjust quality for lossy formats.
4. 4Download the converted files.

Why convert to WebP

WebP is supported by every modern browser and is typically 25–35% smaller than JPEG and much smaller than PNG at comparable quality, while still supporting transparency. Google’s speed tools specifically recommend serving images in next-gen formats, and smaller images mean faster LCP. AVIF compresses even better (often 20%+ beyond WebP) but encodes slower; in-browser AVIF export works only in browsers that support encoding it.

Which format for which image

Photos: WebP or AVIF, or JPEG for maximum compatibility with email and older software. Logos, icons and screenshots with sharp edges or transparency: WebP at high quality or PNG. Vector logos are best kept as SVG on the web; convert SVG to PNG only when a platform demands a bitmap. Converting WebP to JPG or PNG is useful when an app, marketplace or print shop doesn’t accept WebP.

Limitations to know

Everything runs locally via the browser’s canvas, so the inputs you can open depend on your browser: animated GIFs are converted from their first frame only, and HEIC (iPhone photos) works only in browsers that can decode it, such as Safari. JPEG has no transparency — transparent areas become a solid background when converting PNG to JPG.
