Why convert JPG to PNG?
JPEG has one fundamental limitation: it does not support transparency. Every pixel in a JPEG image has a solid colour. PNG, by contrast, supports full alpha channel transparency — making it the go-to format for logos, icons, watermarks, and any graphic that needs to sit over a different background.
Converting your JPG to PNG is also the right choice when you need to edit and re-save an image repeatedly — JPEG degrades on every save, PNG does not.
- Creating logos with transparent backgrounds. If you have a logo as a JPEG and need to remove the background for design work, converting to PNG first is required.
- Watermarks and overlays. Adding a semi-transparent watermark to photos requires a PNG source file. The converter gives you the PNG you need.
- Design composites in Figma or Photoshop. Designers often need PNG assets to layer correctly in design tools. Converting a JPEG ensures it can be positioned over other elements without a white background box.
- Preserving quality through multiple edits. JPEG re-encodes the image every time you save, introducing progressive artefacts. Working in PNG means subsequent saves do not degrade the image further.
Privacy by architecture
Your files never leave your browser.
The converter uses the browser's native Canvas API. Your JPEG images are decoded and exported as PNG entirely on your own hardware — nothing is transmitted, stored, or logged.
- No server upload — conversion happens on your CPU
- No account or sign-up required
- Lossless PNG output — every pixel preserved
