Transform your PNG files into JPEG format instantly within your browser.
PNG (Portable Network Graphics) is a lossless raster format released in the mid-1990s as a royalty-free successor to GIF, after a licensing dispute over the LZW compression algorithm. It compresses images with the DEFLATE algorithm, the same method used by ZIP archives, so every pixel is preserved exactly with no generation loss on repeated saves. PNG also supports a full 8-bit alpha channel for smooth, partial transparency, unlike GIF's binary on/off transparency. These properties make it the standard choice for screenshots, logos, icons, and any graphic with sharp edges, flat colors, or text that needs to stay perfectly crisp.
JPEG is the full-length extension for the same compressed image standard commonly shortened to JPG, published in 1992. Both extensions describe identical file contents; .jpg simply became dominant due to the old 8.3 filename limit of early Windows. The format applies lossy, block-based compression that discards visually minor detail to reduce file size, with an adjustable quality setting that trades detail for size. It supports 24-bit true color and embeds Exif metadata like camera model and capture date. Its main advantage remains near-universal compatibility across cameras, phones, browsers, and operating systems.
