    console.time('toDataURL');
    const base64 = canvas.toDataURL('image/png', 1.0);
    convertBase64UrlToBlob(base64);  // Removing this sentence is faster
    console.timeEnd('toDataURL');

    const blob: any = await new Promise(resolve => {
      console.time('toBlob');
      return canvas.toBlob((blob) => {
        console.timeEnd('toBlob');
        resolve(blob)
      }, 'image/png', 1.0)
    });

The above results show that the toBlob method does not have any advantages. On the contrary, removing the conversion code from toDataURL will result in a more significant improvement. If the execution order of toDataURL and toBlob is swapped, toDataURL will clearly have an advantage over toBlob (even if the conversion code is not removed). I have searched for a lot of content and many articles have pointed out that toBlob not only has advantages in memory and performance. But my test results do not support this conclusion, and often toDataURL performs better
