Convert JPEG to PNG — Free Online Converter

Tips for Converting JPEG to PNG
- PNG files are typically 3–5× larger than the equivalent JPG — use this format only when lossless quality or transparency is required.
- JPG compression artefacts are permanent and remain visible in the PNG; converting back to JPG does not restore the original.
- To add a transparent background after conversion, open the PNG in an image editor and use the background-erase or magic-wand tool.

Why Convert JPEG to PNG?
People convert JPEG to PNG to switch from lossy JPEG to lossless PNG to preserve full image quality, and to gain transparency support that JPEG lacks.
Lossless PNG is the right choice whenever you plan to edit the image further or need pixel-perfect quality for UI assets, icons, or print. Unlike JPEG, saving PNG multiple times introduces no additional quality loss.
