Convert Flat or Scanned PDFs into Mobile Web Forms Built to Support WCAG 2.1 AA
Scanned and flat PDFs have no form fields at all, so they cannot be tagged until someone rebuilds them. ToWebForm detects the fields automatically and generates a responsive web form designed around the WCAG 2.1 AA success criteria that matter most for forms.
The problem: A scanned PDF is just an image to a screen reader. Making it usable usually means rebuilding the form in Acrobat first and then remediating it, which doubles the work.

How ToWebForm Replaces PDF Form Remediation
Flat and scanned PDFs are images of a form with no interactive fields, so assistive technology cannot identify where to type or what each blank means. Before they can be remediated, someone has to recreate every field. This is why scanned forms are often the last items left on an accessibility backlog.
ToWebForm uses vision analysis to detect text boxes, checkboxes, dates, signature lines, and tables on flat or scanned PDFs, along with their labels and coordinates. It then generates a responsive HTML form designed around the WCAG 2.1 AA criteria most relevant to forms: Info and Relationships (1.3.1), Identify Input Purpose (1.3.5), Contrast (1.4.3), Reflow (1.4.10), Keyboard (2.1.1), Focus Visible (2.4.7), Error Identification (3.3.1), and Labels or Instructions (3.3.2).
The original scan stays the official record. Answers are stamped onto the exact detected coordinates, long responses move to an overflow addendum page, and the finished PDF is delivered to your team. Accessibility details such as ARIA labels, helper text, and autocomplete tokens can be adjusted per field in the Accessibility Overrides Workbench.
Key Facts
- Automatic field detection on flat and scanned PDFs
- Single-column reflow at 320px (WCAG 1.4.10)
- 48x48px minimum touch targets on inputs, checkboxes, and buttons
- Autocomplete tokens for name, email, phone, and address fields (WCAG 1.3.5)
- Focus moves to the first invalid field with a linked error message (WCAG 3.3.1)
- Per-field ARIA and helper text overrides without editing the PDF
1. Upload the PDF you already use
Interactive AcroForms and flat or scanned PDFs both work. Fields, labels, and coordinates are detected automatically.
2. Respondents fill out a semantic web form
Single-column HTML built to support WCAG 2.1 AA, with labels, fieldset groups, keyboard focus order, and screen-reader status messages.
3. Your team receives the original PDF
Answers are stamped onto the exact coordinates of the original document, encrypted with AES-256-GCM, and ready for your existing process.
02 / Side-by-Side Comparison
Manual Acrobat Tagging vs. Remediation Agencies vs. ToWebForm
Three ways to handle an inaccessible PDF form, compared on cost, phone use, assistive technology, maintenance, language access, and data handling.
| Criterion | Manual Acrobat Pro Tagging | PDF Remediation Agencies ($25 to $75/page) | ToWebForm |
|---|---|---|---|
| Starting from a flat or scanned PDF | Recreate every field with Prepare Form, then run OCR, tag, and fix reading order | Often priced as a rebuild, above standard per-page remediation rates | Fields, labels, and coordinates are detected automatically. Review and publish in minutes |
| Cost model and turnaround | Staff time: often 1 to 3 hours per complex form to build and verify the tag tree, reading order, and field tooltips | Commonly quoted at $25 to $75 per page, with turnaround measured in days or weeks per batch | Flat monthly plan with unlimited standard submissions. Upload a PDF and get a working web form in seconds |
| Phone use (WCAG 1.4.10 Reflow) and touch targets | Still a fixed 8.5x11 page. Respondents pinch, zoom, and scroll sideways on a 320px screen | Same fixed page layout. Tags help screen readers but do not make the page reflow on phones | Single-column responsive HTML that reflows at 320px with 48x48px minimum touch targets |
| Screen reader and keyboard use (WCAG 1.3.1, 2.1.1, 4.1.3) | Depends on tag quality and the PDF reader. Mobile screen readers often read fields out of order | Usually tested in desktop Acrobat with JAWS or NVDA. Mobile reader behavior varies | Semantic labels, fieldset and legend groups, visible focus rings, linked error messages, and ARIA live status regions |
| When one line of the form changes | Re-exporting from Word or InDesign drops the tags, so the file must be re-tagged and re-checked | Send the file back and pay the per-page rate again | Edit the label, help text, or screen-reader hint in the builder. No re-remediation of the PDF |
| Multilingual and Title VI LEP access | Translate, re-typeset, and re-tag a separate PDF for every language | Each translated PDF is a new remediation job billed per page | One link where respondents choose from 18 supported languages (active languages depend on your plan), including right-to-left Arabic and Urdu. Bidirectional translation stamps English answers onto your original PDF on every plan, including Free |
| Back-office output and PII retention | Respondents email or upload the filled PDF, which then sits in inboxes | Same as manual tagging. The workflow after remediation does not change | Answers are stamped onto the exact coordinates of the original PDF and encrypted with AES-256-GCM. Team plans can enable Zero-Storage Fill and Download mode so no respondent PII is stored |
Agency rates reflect commonly quoted per-page pricing for form remediation and vary by vendor, document complexity, and turnaround.
03 / Language Access and Privacy
Beyond Accessibility: Language Access and Zero-PII Options
Bidirectional Answer Translation
Title VI language access · 18 supported languagesRespondents choose from 18 supported languages (active languages depend on your plan), including right-to-left Arabic and Urdu. They answer in their own language, and open-text answers are translated back into your PDF language before stamping, with both versions kept in a Bilingual Verification Log. Included on every plan, including Free.
Zero-Storage Fill and Download Mode
No respondent PII retained · TeamFor court, records, and resident forms where you should not hold the data. Respondents complete the web form, and the official stamped PDF is generated in memory and streamed straight to their browser. No answers are written to the database.

Remediating PDF forms for clients? Convert the whole library instead of tagging it page by page
Web, digital, and accessibility agencies use the ToWebForm Team plan to turn a client's PDF form library into web forms built to support WCAG 2.1 AA in an afternoon, then keep those forms current without re-billing per page. Your client still receives the original PDF for every submission.
A workspace per client
Keep each client’s forms, submissions, and team access separate in Multiple Workspaces.
Their domain, their brand
Publish on a custom subdomain such as forms.yourclient.com with White-Label Branding and no ToWebForm badge.
5 seats included
Give your team and the client’s staff role-based access as Owner, Admin, or Member, and add seats as you grow.
Zero-Storage when required
Turn on Zero-Storage Fill and Download mode for clients whose respondents’ answers must not be stored.
