Format Recommendations
For Camera Captures
The default JPEG format from your iPhone camera works well. DocSnap handles the compression automatically. No special camera settings are needed.
For Scanned Documents
If you're scanning documents with a dedicated scanner or scanning app, use PNG for the best OCR accuracy. PNG preserves fine text details that JPEG compression might blur.
For Existing Documents
If you already have documents in PDF format (from email attachments, downloads, etc.), upload them directly. There's no need to convert PDFs to images first.
Unsupported Formats
The following formats are not currently supported:
- HEIF/HEIC (iPhone Live Photos format -- convert to JPEG first)
- TIFF
- BMP
- Word documents (.docx)
- Excel spreadsheets (.xlsx)
If you have a document in an unsupported format, you can usually convert it to PDF or JPEG using the built-in iOS sharing features before importing into DocSnap.
