JPGPNG
Move a lossy JPEG into a lossless PNG container so every subsequent edit and save stays artifact-free.
JPG is a lossy delivery format: it uses DCT-based compression and chroma subsampling to discard detail your eye rarely notices, which keeps photos small but bakes in permanent artifacts. PNG is the opposite — a lossless DEFLATE format that stores every pixel exactly and supports an alpha channel. Converting JPG to PNG wraps your image in that lossless container so future edits, crops, overlays, and re-saves no longer compound JPEG artifacts. Note the honest limit: PNG cannot recover detail the JPEG already threw away. What it buys you is a clean, non-degrading master to work from, plus the ability to add transparency — ideal before you cut out a subject, layer text, or feed the image into an editing pipeline.
Convert JPG to PNG on the canvas
Drop your file onto a Brainy Canvas board, connect the converter node, and download the result. New accounts get free starter credits — enough for roughly 200 image conversions — with no card required.

Attach the Image Converter
Connect the file into the Image Converter node and select PNG as the target format. The job runs server-side with ImageMagick, re-encoding pixels losslessly.
3
Download the PNG
A lossless PNG lands on the node in seconds. Save it, or route it into another node to mask, resize, or annotate.
