Processing modes
One option controls what Porter does with your PDF.
| mode | Work | Credits |
|---|---|---|
fix_and_validate | Repair, then return before/after validation. Default. | Normal page credits |
fix_only | Repair without accessibility validation. | Normal page credits |
validate_only | Validate the original without changing it. | Zero |
Validation outcomes
A successful check can find accessibility problems. Those findings appear in the report and do not make the job fail. A checker that cannot finish produces a failed job. If a repaired output is available, has_output remains true.
Fix-only reports validation.status: "skipped". Input validation and repair integrity checks still apply. Validation-only returns the original’s report under before, with after: null, and has no repaired download.
Supported inputs
Supply an unencrypted PDF with a usable text layer. Image-only OCR is not supported. No model, quality, or layout tuning is needed.
