HTML is usually the better default when reviewers will read a proposal online, search it, use assistive technology, or work through frequent revisions. PDF is the better fit when fixed page layout, print fidelity, or a stable downloadable record matters. If you need both accessible online reading and precise presentation, provide an accessible HTML version alongside an accessible PDF. The right choice also depends on the review platform, audience, and solicitation or approval requirements.
HTML vs. PDF for proposal review
| Review need | HTML | |
|---|---|---|
| Online reading and devices | Usually the stronger choice: it adapts to browser settings and different screen sizes. Massachusetts EOTSS and GOV.UK guidance favor HTML for web-based content and online reading. Massachusetts EOTSS; GOV.UK | Can be less convenient on mobile, where reviewers may need to download or zoom the document. Accessibility work is also needed. Massachusetts EOTSS |
| Accessibility | Can use browser settings and semantic structure, but the page still needs clear headings, meaningful links, keyboard access, and accessible controls. GOV.UK | Can be accessible when deliberately structured and tagged. A scanned document needs OCR to make its text searchable and readable by assistive technology. GOV.UK; Section508.gov |
| Revisions and maintenance | Usually easier to update during review and maintain as the content changes. Massachusetts EOTSS | Provides a stable snapshot, but a revision means distributing a new file and identifying the new version. Massachusetts EOTSS |
| Comments and approval | Can be paired with a web form or controlled web workflow. The format alone does not establish an audit trail. | Adobe Acrobat documents sharing options for feedback, approval or rejection, and view-only access. Link access can be limited to invited people or an organization, or opened to anyone with the link. These are Adobe workflow capabilities, not proof that PDF approval is inherently more reliable. Adobe Acrobat sharing guidance |
| Print and visual fidelity | Less suited to precise page-by-page print layout. | Usually the stronger choice when fixed layout or print fidelity is essential. Massachusetts EOTSS |
| Static records and archives | Can remain the accessible reading version while the proposal content is maintained. | May suit a static, non-editable download or archive. For government publishing attachments, GOV.UK specifies PDF/A in that context; it is not a universal rule for private proposals. GOV.UK |
When HTML is the better choice
Choose HTML when the proposal is primarily an online document and reviewers need it to work across devices, adapt to browser settings, or change during the review cycle. Semantic headings and links make content easier to navigate, while a web-based process can bring reading and feedback together.
HTML is not automatically accessible. Use meaningful heading levels and link text, ensure keyboard access, and make any forms and controls usable with assistive technology. GOV.UK recommends publishing in HTML wherever possible so documents can use readers’ custom browser settings, and advises providing an accessible version if a PDF must remain online. GOV.UK: Publishing accessible documents
When PDF is the better choice
Choose PDF when reviewers need a print-ready document, a fixed visual layout, or a static file that represents a particular version of the proposal. It can preserve page composition in a way that a responsive web page is not designed to do.

That stability comes with a version-control responsibility: when the proposal changes, issue a replacement file and make its version clear. For accessibility, check that the PDF has tags and a logical reading order; a polished appearance alone does not make it usable. Section508.gov states that PDF documents must be tagged to be accessible. Section508.gov PDF guidance
How to make the approval process reliable
Review quality depends on the process around the document, not just its file type. Set up the review so participants know which proposal is authoritative, how to comment, and how the final decision will be captured.

- Identify the version. Put the proposal’s version and date where reviewers can find them, and ask approvers to confirm which version they reviewed.
- Define access. Give reviewers the access they need without exposing the proposal more broadly than intended. Adobe’s documented PDF-sharing options include anyone-with-link, organization-only, and invited-people-only access. Adobe Acrobat sharing guidance
- Specify feedback and the decision record. Tell reviewers where to submit comments, who makes the decision, and where the decision will be recorded. A format by itself does not provide a complete audit trail.
- Choose an accessible signing method if needed. Use a web form or fillable PDF only after checking that it works for the intended users. Section508.gov says PDF forms should support keyboard users and logical tab order, and notes that websites generally use HTML form elements. E-signature tracking depends on the service and its configuration, not on HTML or PDF alone. Section508.gov forms guidance
Check requirements that apply to your proposal
Before choosing a format, check the solicitation, contract, funder, procurement, records, and jurisdiction requirements. Government rules are not universal requirements for private-sector proposals. For example, GOV.UK’s attachment profile requires HTML5 for new attachments and PDF/A for static, non-editable downloads or archives; it also warns that scanned PDFs need OCR to become searchable and screen-reader readable. These requirements describe that government publishing context, not every proposal workflow. GOV.UK attachment guidance
U.S. Section 508 guidance says documents such as requests for proposals hosted by agencies must meet applicable accessibility requirements. Treat its PDF-tagging guidance as a production checkpoint, not as a guarantee that every tagged PDF will meet every reader’s needs. Section508.gov: Requiring Business Partners to Provide Accessible Documents
