Conversions can be chained by using result file link as source file in successive conversion. Result file URL will be treated exceptionally and conversion will be processed in high performance. Example:
Convert JPG to PDF
Request:
POST https://v2.convertapi.com/jpg/to/pdf?secret=XXX&storefile=true&file=https://example.com/file1.jpg
Result:
{
"ConversionTime": 2,
"Files": [
{
"FileName": "file1.pdf",
"FileSize": 19456,
"Url": "https://v2.convertapi.com/d/ZYXFNMPT/file1.pdf"
}
]
}
Request:
POST https://v2.convertapi.com/jpg/to/pdf?secret=XXX&storefile=true&file=https://example.com/file2.jpg
Result:
{
"ConversionTime": 2,
"Files": [
{
"FileName": "file2.pdf",
"FileSize": 19456,
"Url": "https://v2.convertapi.com/d/QAZEDCTG/file2.pdf"
}
]
}
