🛠 Common Reasons & Solutions
1. Unsupported File Type
Ensure the file you’re trying to open is a PDF or another format supported by A1 PDF Editor. The app may not support certain image, DOCX, or encrypted formats.
2. Incomplete Download
If you're importing from cloud storage or another app and the download was interrupted, the file may be corrupted.
Fix:
Delete the file.
Re-download or re-import it completely from the source.
3. Corrupted File
If the PDF itself is damaged, A1 PDF Editor might not be able to read it.
Fix:
Try opening the same file in Apple’s Files app or Preview.
If it works there, re-import into A1 PDF Editor.
If it doesn't, ask the file sender to share a new copy.
4. Large or Complex PDFs
Very large or heavily layered PDFs may not open properly on older devices.
Fix:
Try opening on a newer iPhone or iPad.
Split the file using a desktop PDF tool before importing.
