About JPG to PNG Converter
JPG is a lossy format tuned for photographs, producing small files but with no transparency. PNG is a lossless format with full transparency support, ideal for logos, icons, and screenshots.
Converting JPG to PNG produces a lossless file that opens in virtually every browser, operating system, and image editor. Drop your file above and it is decoded and re-encoded as PNG entirely inside your browser, so even sensitive images never leave your device.
To use it, drop your JPG file into the upload area or click to pick one from disk. The conversion runs as a single pass — the JPG bytes are decoded into a pixel buffer and re-encoded as PNG losslessly, so the output pixels are identical to what the JPG decoded to. Output dimensions match the source; to resize as well, run the image resizer before or after the conversion. A typical photo converts within a second or two on a modern device.
