About JPG to PNG Converter
Select any number of JPEG files and each is decoded and re-encoded as PNG on a canvas in your browser. Every converted file gets its own download button, along with its dimensions and before/after sizes.
Common uses
- Meet an upload form that only accepts PNG
- Prepare images for tools that expect lossless input
- Convert a folder of photos without installing anything
Limitations
- PNG is lossless but usually larger than the source JPEG — this conversion does not improve quality that JPEG already discarded.
