And the result is a JPEG holding both the original JPEG and ... text? JPEG and text is a horrible idea. Even with best quality settings, compression artefacts are visible.<p>Why don't you offer SVG export? That would solve all problems and make the embedding into websites really easy. You even can embed your JPEG into SVG (base64, you will loose a ~30% in file size but the lesser storage for the text gives it back).
