Convert HEIC to JPG/PNG and control size before sharing or uploading.
iPhone & Android File Workflows Hub
Mobile scans and HEIC images often fail uploads. Use these phone-first workflows to produce clean, portal-friendly files.
What this hub covers
Mobile workflows fail most often because of HEIC images, oversized camera scans, and “auto-enhance” filters that inflate file size. This hub shows repeatable, phone-first workflows that produce portal-friendly files.
Most common mobile problems
Use controlled compression or rebuild the PDF from compressed images.
Choose the right export path for readable documents (avoid re-compressing repeatedly).
Recommended mobile workflow
- Scan: use your phone scanner, but avoid aggressive “sharpen” filters unless necessary.
- Export: save as PDF, then check file size.
- Compress: run PDF Compress.
- If still too large: convert pages to images, compress with Image Compress, then rebuild via Image to PDF.

FAQ
Should I send “as document” on WhatsApp?
Yes. Sending as a photo often triggers stronger compression. For scanned documents, “document” is usually better.
What is the best format for forms?
PDF is typically safest for portals. Use JPG only when the portal explicitly asks for images.
