Why convert JPG to PNG format?
➕
PNG format uses lossless compression and supports alpha channel transparency, making it ideal for logos, vector graphics, text screenshots, and web design assets.
Is my image data kept safe and private?
➕
Yes! Processing occurs 100% inside your web browser via HTML5 Canvas and JavaScript Web Workers. Your files are never uploaded to any cloud server.
Can I convert multiple JPG images at once?
➕
Absolutely. You can select or drag-and-drop multiple JPG files into the queue and download all converted PNGs in a single ZIP file.
Does converting JPG to PNG increase image file size?
