Convert JPG images to PNG. Batch upload supported — everything runs locally.
All processing happens in your browser — files never upload anywhere.
JPG to PNG converts your JPEG (.jpg) files to Portable Network Graphics (.png) directly in your browser using the browser's built-in Canvas 2D encoder. No signup, no watermark, no upload — your JPG stays on your device from start to finish. Portable Network Graphics is typically used for lossless images with transparency, and Toolspace's converter preserves the source at the highest quality the target format allows.
