When this workflow is the right choice
Teams publishing to strict upload limits and performance-sensitive pages. 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.
- Choose output format first
- Enable target-size logic
- Set KB limit per image
- Keep quality floor policy
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.
- No visible artifact spikes
- Target achieved for majority of files
- Outliers flagged for manual review
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.
