When this workflow is the right choice

Content teams preparing iPhone imagery for design tools. This guide is built for repeatable output, not one-off editing.

If your team handles many files per day, deterministic presets and queue-safe export rules matter more than manual tweaks.

Recommended Operimage setup

Start with a clean preset chain: Input -> Process -> Preview -> Export. Keep overwrite disabled until your output QA is approved.

Use before/after preview on a representative subset, then run the full queue. This avoids expensive reruns and naming conflicts.

  • Input: HEIC
  • Output: PNG
  • Include subfolders when ingesting shoots
  • Strip metadata only when needed

Quality control checklist before full batch

Large runs should always pass a short preflight. Check framing, detail retention, and destination path behavior before scaling up.

If output quality is inconsistent, split the queue by asset type and apply dedicated presets per category.

  • Detail retention on skin/fabric
  • Folder tree preserved
  • Post-export editability validated

FAQ

Can I run this on large folders safely?

Yes. Use include subfolders + preserve structure when needed, and validate a small subset before full export.

Should I keep metadata for this workflow?

Keep metadata for archival/internal pipelines. Strip EXIF/IPTC for privacy-sensitive delivery.

What is the fastest way to avoid quality regressions?

Use preview-first checks and save stable presets. Avoid ad-hoc slider changes during production runs.
