Use your phone or WeChat first
OpenOnPhone does not plan to preview this common format because phones and WeChat already provide a viewer for this class of file.
Back to file pickerWhat is PDF?
PDF is a fixed-layout document format used for reports, forms, receipts, drawings, and shared documents.
Common MIME examples: application/pdf
Why it can be hard on phone
- Large PDFs can be slow on older phones.
- Scanned PDFs behave like images and may need OCR for search.
- Some PDFs require fonts, forms, or security features that mobile viewers handle differently.
What to try next
- Use the phone's built-in PDF viewer or WeChat preview first.
- If a specific PDF still fails, ask the sender for a screenshot or image export.
- OpenOnPhone does not plan to add PDF preview unless there is a very specific edge case.
