⚙️ Cross-Format Pixel Transcoding: WebP, PNG-24 & Baseline JPEG
Modern digital workflows constantly run into format friction: images saved from websites arrive as `.webp` files that legacy office apps or print shops reject, while raw `.png` screenshots weigh several megabytes and slow down web pages. True format conversion requires decoding the source bitstream into an uncompressed RGBA pixel buffer and re-encoding it with the target codec.
DH Tools utilizes hardware-accelerated HTML5 Canvas transcoding to convert seamlessly between WebP, PNG, and JPEG in bulk—automatically handling alpha-channel compositing and stripping unnecessary camera metadata.
