JPG is a compact, widely supported image format designed for photographs and other images with continuous color. Its lossy compression can create much smaller files, although repeated editing and saving may reduce visual quality.
Open JPG ConverterPNG stores images with lossless compression and supports full alpha transparency. It is commonly used for logos, interface graphics, screenshots and artwork that needs sharp edges or a transparent background.

Convert JPG to PNG online in your browser in batches of up to 100 files. Review the result and download it without uploading the source.
PNG is a practical choice for graphics, screenshots and images that need transparency. The JPG source is commonly used for photos, previews and broadly compatible uploads.
JPG is a lossy photo format, so the conversion keeps the pixels available in the decoded source but cannot restore detail already removed by compression. PNG is lossless and can preserve transparency only when the source actually contains it. Keep the original until you have checked the converted file in its destination app.
Choose up to 100 images, with a 30 MB per-file limit and a 500 MB combined limit. Files are processed sequentially and multiple results download as one ZIP. Supported processing happens on this device, so the source does not need to be uploaded to zer.ai.
