Common Errors & Troubleshooting

400 Bad Request Unsupported source-to-target format conversion pair
Check the /api/v2/public/convert docs for supported format combinations before sending the request
Empty response body Input file is malformed or corrupt
Validate the file locally first, then re-upload — ensure the file is not zero bytes
Conversion timeout Very large or complex files take too long to process
Simplify the input file (reduce node count in SVGs, compress PDFs) and retry with a smaller file
