Workflow map

Keep the batch predictable from input to export

These guides work best when resize, conversion, naming, and export rules stay in one preset instead of becoming separate manual passes.

Input

Bring in files, folders, or nested client deliveries without breaking structure before processing starts.

Process

Apply exact, longest-side, or percentage rules, then decide whether fit, fill, or padding matches the output requirement.

Export

Lock the batch with naming, metadata, and output policies so the same preset behaves the same way tomorrow.

When this workflow is the right choice

Creator and commerce teams publishing to multiple channels daily. 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.

  • Resize mode: Exact / Longest / Percentage
  • Behavior: Fit / Fill / Pad
  • Use social preset dimensions
  • Preview before full queue

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.

  • Aspect ratio safety confirmed
  • No important crop loss
  • Output dimensions match channel spec

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.
