Conversor JPG para PNG Online Gratuito

PNG supports lossless compression and transparent backgrounds, making it better for logos, screenshots, and images with text or hard edges. If you're editing an image further, PNG preserves quality through multiple save cycles whereas JPEG degrades each time.

No. Converting from JPEG to PNG stops further quality loss, but it cannot recover detail already lost during the original JPEG compression. If the JPEG looks fine, the PNG will look identical — just larger in file size.

No. The conversion runs entirely in your browser using the Canvas API. Your file never leaves your device and nothing is stored or transmitted to any server.

JPEG uses lossy compression optimised for photos, achieving very small file sizes. PNG uses lossless compression, which preserves every pixel exactly — this results in larger files. PNG's advantage is quality retention and transparency support, not smaller size.

Currently the tool processes one image at a time. To batch convert, use each image in sequence — clear the previous result, drop the next file, and download. For large batches, a desktop tool like ImageMagick or XnConvert is more efficient.
