How does the pdf accessibility preflight work?

1. 1
   Define the approved scope

   Reference. Stable reference for this exact supplied population.

2. 2
   Enter task-specific evidence

   Parse the actual bounded classic PDF 1.x cross-reference, catalog, page and structure objects locally. Inspect conventional title, default language, marked/suspect flags, per-page structural indicators, standard figure alternative-text presence and supported unfiltered text-showing operators. Preserve original hashes and report unsupported/encrypted/corrupt files explicitly. Human reading order, text alternatives, contrast, form semantics and conformance remain separate unperformed checks.

3. 3
   Inspect complete findings

   Review all named calculations, original source bindings and unresolved findings.

4. 4
   Keep recoverable work

   Exact original bytes and unfinished strings save locally. Restore validates exact tool, revision, row shape, source hashes and history before replacement. Earlier work and purchases remain separate.

5. 5
   Prepare the finalized pack

   Prepare 7 plus selected attachments complete files, then download them free. Review the fictional sample below.

Apply the steps above to the supported inputs. Use the listed source sections to review the rule basis, assumptions and limits.

• Create Accessible PDFsSupports named source-bound preparation and precise reviewed criteria. Current applicability and actual outcomes require accountable review. Section 508 PDF creation and testing resources. Document properties, tags and content structures support evaluation, while semantic reading order, text alternatives, forms and full conformance require additional manual review.US General Services Administration.

• PDF Reference, Sixth Edition, Version 1.7Supports named source-bound preparation and precise reviewed criteria. Current applicability and actual outcomes require accountable review. Sections 3.4.3 and 3.6 define classic cross-reference entries and page/catalog structure. Sections 10.6 and 10.8 describe structural tags, default language and alternate descriptions. This implementation supports bounded classic PDF 1.x structures only. Presence checks cannot prove correct logical order or meaningful text alternatives.Adobe. Reviewed 2026-10-09.

Common questions

What still needs review?

This browser preparation retains original customer evidence and selected source-approved criteria. Actual manual tests, authorization, delivery, signatures, employment status and legal applicability remain responsible human decisions. PDF checks cover only supported structural indicators, not semantic accessibility or conformance. No external scan, filing, remote AI or provider is called. Exact sources stay in this browser. Original files are not saved to the cloud.

At most 500 rows/200000 characters per table, 20 files/10 MB each/25 MB total, 900 KB input and 8 MB output metadata. PDF has at most 100 pages and 20000 structure nodes.

No statement or preparation table proves accessibility, employment eligibility, worker classification or current filing/legal duties. Your operative source versions and actual evidence remain required.
