Frequently asked questions
- Which annotation formats can I convert between?
- The converter reads COCO JSON, YOLO TXT, Pascal VOC XML, CVAT XML, LabelMe JSON, CSV, TSV, and JSONL, and detects the input format automatically. You can export to COCO, YOLO, Pascal VOC, CSV, and the other supported formats.
- Do I need an account to convert annotations?
- No. The converter is free and works without signing up. An account is only needed if you want to keep labeling, reviewing, and versioning the dataset in a LabelOp workspace.
- Can I convert a whole dataset at once?
- Yes. Upload a ZIP archive or several annotation files together. Up to 300 files, 10 MB per file, and 25 MB in total can be converted in one run.
- Are my files uploaded?
- The files you select are sent to LabelOp servers for processing, and the result comes back as a download. You do not need an account.
