How PNG to WEBP conversion works
The Portable Network Graphics format uses lossless DEFLATE compression and supports a full alpha-transparency channel, preserving every pixel exactly as encoded. Converting to WEBP produces an image file that supports both lossy and lossless encoding with transparency and animation, and usually compresses better than JPEG or PNG. This conversion changes the file's encoding, compression method, and supported feature set. The output is pixel-accurate: no further quality is lost beyond what the source already encoded. This makes WEBP the practical choice when the destination system requires it or when the target format offers better compatibility or compression. 1converter runs this conversion on the server: your file is uploaded encrypted over HTTPS, converted using trusted open-source libraries, and the output is held for 24 hours before automatic deletion.
