Size Limit
The upload limit per file is 10MB. The system will prompt before upload if the limit is exceeded.
Scanned or image-based PDFs have limited recognition effectiveness. If the document is a scanned version, it's recommended to use the Image OCR feature to upload images separately for better recognition results.
Usage Recommendations
- Ensure documents have a text layer — Pure image PDFs cannot extract text; convert them to versions with text layers
- Focus document content — Large documents with multiple unrelated topics work better when split and generated separately
- Check format compatibility — Non-standard DOC files may occasionally parse incompletely; converting to DOCX is recommended
Common Questions
QWhat if the uploaded PDF content is an image?
A
You can use the Image OCR feature to screenshot images from the PDF and upload them, or directly upload image files for recognition.
QWhat if I need to upload a document larger than 10MB?
A
You can split the document into smaller parts, upload and generate mind maps separately, then merge and organize them in the editor.
