JPG to PNG Converter
Upload a JPG (JPEG) image and convert it to PNG format in your browser. PNG is a lossless format — once converted, the image can be edited and re-saved repeatedly without any further quality degradation, unlike JPG which loses more detail each time it's re-compressed.
This is useful when you need to use a JPG image in a workflow that requires PNG input, or when you want to preserve the current state of a photo as a lossless copy before making edits. Note that converting from JPG to PNG won't restore detail that was already lost during the original JPG compression — the PNG will be a pixel-perfect copy of the JPG, but at a larger file size.
The conversion runs entirely in your browser using the native Canvas API. Nothing is uploaded to a server.

Frequently asked questions
Will converting JPG to PNG improve image quality?▼
No. The conversion preserves the image exactly as it appears in the JPG, but cannot restore detail that was already discarded by JPG compression. The PNG output will be a lossless copy of the current pixel data — further edits and saves won't degrade it further.
Why is the PNG file larger than the original JPG?▼
PNG uses lossless compression, which preserves every pixel perfectly but produces larger files than JPG's lossy compression. A typical photo that's 500 KB as a JPG may be 2-5 MB as a PNG. This is the expected tradeoff for lossless quality.
Does this tool upload my image to a server?▼
No. The entire conversion happens in your browser using the Canvas API. Your image never leaves your device.
