ReflowPDF is a browser-based PDF editor that edits document structure rather than placing text over a frozen page. When a user adds a table row, deletes a column or rewrites a paragraph, the content below shifts, columns resize and page breaks adjust. It is built by a single developer, Vlad Kyslenko, on a custom CSS layout engine called FlexPDF.
Every export is a Tagged PDF that validates as PDF/UA-1 in veraPDF, and each file carries its editable source, so it can be reopened and changed later. The site says visitors can try the editor in the browser without signing up, with paid plans adding PDF/A-3a, PDF/UA-2 and preflight accessibility checks.
A user starts from a built-in template, a blank page or an existing PDF. Templates and blank pages are built on real document structure. Third-party PDFs can be brought in through optional AI import, which rebuilds the file as an editable document once, after which it behaves like any other ReflowPDF document.
Editing happens in a visual editor with a block panel, a layers tree and style controls. Users click an element, type, or right-click for table operations. On export, the engine renders the structure back to PDF and embeds the source, encrypted with AES-256-GCM, so reopening the file later needs no AI and nothing is sent to a server.
The core feature is structural reflow. Tables split across pages with repeated headers, totals move down when rows are added, and page breaks recalculate. Accessibility tools include alt text, document language and title settings, plus author checks that flag missing alt text, skipped heading levels, tables without header cells, colour contrast, link text and reading order.
Export options cover Tagged PDF and PDF/UA-1 on every plan, PDF/A-3a archival output that also validates at the 3b and 3u levels, and PDF/UA-2 on PDF 2.0. The site reports that all 51 built-in templates pass veraPDF with zero failures, and it offers sample files to download and test independently.

Yes. The free plan includes the full editor, unlimited pages and editing, built-in templates and PDF/UA-1 export. It allows 50 watermark-free pages per month, after which exports carry a small watermark. You can try the demo without signing up.
Yes. Each export carries its editable source inside the file, encrypted with AES-256-GCM. Reopening it in the editor needs no AI and no re-conversion, and the file still opens in any PDF viewer.
Every export is a Tagged PDF with a structure tree that validates as PDF/UA-1 in veraPDF, on every plan. The site cites this as the bar required by the EU Accessibility Act and US Section 508. Pro and Max add PDF/A-3a and PDF/UA-2 export.
Yes, through optional AI import, which rebuilds a third-party PDF as an editable document once. It is counted by the source PDF's page count, with 3 pages per month on Free, 150 on Pro and 1,000 on Max. Extra packs cost $8 per 100 pages.
PDF/A-3a is an archival export that embeds fonts and the editable source, and it also validates at 3b and 3u levels. PDF/UA-2 is the second edition of the accessibility standard, based on PDF 2.0. Both are Pro and Max toggles, and exports default to PDF/UA-1.
The sources do not list any third-party integrations. Users can sign up with email or Google, and exported files are regular PDFs that can be emailed or stored anywhere.
