Understand why HEIC fails on some portals and the best quality settings.
HEIC to JPG
HEIC is efficient, but many portals reject it. Use these compatibility-first methods to produce a clean JPG and keep file sizes small.
iPhone photosUpload compatibilityQuality settingsSize reduction
Quick checklist
- Remove unnecessary pages first
- Compress once, then re-check size
- If scanned: rebuild from compressed images
- If still too large: split into parts
Most cases reach the target without quality loss if you avoid over-compressing early.

If your JPG is still too large, resize for forms and web.

If you’re converting to email files, check attachment limits first.
Step-by-step workflow
- Decide whether you need JPG or PNG: Use JPG for photos; use PNG only when you need transparency or sharp graphics.
- Convert on iPhone (fastest): Settings → Camera → Formats → ‘Most Compatible’ for future photos; or Share → Save to Files → convert via compatible apps.
- Convert on Windows/macOS: Use built-in Photos/Preview export where supported to produce a JPG copy.
- Reduce size if needed: After conversion, resize to sensible dimensions and compress for upload limits.
- Keep originals: Store the original HEIC if quality matters; upload a derived JPG copy when compatibility matters.
Technical tips that prevent quality loss
- HEIC is efficient, but many upload portals and older systems do not accept it.
- If you convert HEIC → JPG repeatedly, you can accumulate quality loss. Convert once from the original.
- For documents, prefer a scan-to-PDF workflow rather than multiple images when the portal expects PDFs.
- If location privacy matters, remove EXIF before sharing photos publicly.
FAQ
Why does my portal reject HEIC?
HEIC support is inconsistent across browsers, operating systems, and upload systems. JPG is the safest option.
Is HEIC better quality than JPG?
HEIC can store high quality at smaller sizes, but JPG is the most compatible for uploads.
Can browsers convert HEIC reliably?
Not reliably across all browsers. A dedicated HEIC converter requires special decoding support.
Will you add a HEIC converter tool?
Yes—HEIC conversion is on the roadmap. This page provides the best current workflows for compatibility.
