ReflowPDF is a browser-based PDF editor with true structural reflow. Unlike tools that position text in fixed boxes, it builds real semantic document structure โ tables, headings, lists โ so editing content reflows the document like a word processor. Add a table row and everything below repaginates automatically, headers repeat across pages, and page breaks adjust on every edit.
It runs entirely in the browser with no software to install. The rendering engine is written from scratch with zero external dependencies โ no headless Chrome, no Node โ and supports modern CSS including Flexbox and Grid.
Exports pass PDF/UA-1 and PDF/A-3a validation on veraPDF with zero failures, making it suitable for accessibility compliance work under the EAA, ADA Title II and EN 301 549.
A standout feature is round-trip editing: the editable source is embedded directly inside the exported PDF, so the file you download is the same file you reopen to keep editing โ no server-side document storage. There is an open demo with no signup.
Built for translators and localization teams, accessibility compliance teams, and regulated SMBs.
A startup from GREER, the United States that is founded by Vladyslav Kyslenko.

Translators and localization teams who deal with text expansion and contraction that breaks fixed layouts, accessibility compliance teams working under the EAA, ADA Title II and EN 301 549, and regulated SMBs such as bookkeepers, accountants and paralegals who need reliable, accessible documents without buying Acrobat.
True structural reflow. ReflowPDF builds real semantic document structure โ actual tables, headings and lists โ instead of positioning text in fixed boxes like most browser PDF tools. When you edit, the document repaginates like a word processor: add a table row and everything below shifts, headers repeat across pages, page breaks adjust automatically. The rendering engine is written from scratch with zero dependencies, no headless Chrome or Node.
Because the output is correct by construction, not patched after the fact. Chromium-based tools position content absolutely and cannot produce properly tagged, accessible PDFs. ReflowPDF exports pass PDF/UA-1 and PDF/A-3a validation on veraPDF with zero failures, straight from the browser, with no manual remediation in Acrobat. It also embeds the editable source inside the exported PDF, so the file you download is the same file you reopen to keep editing.
It started from frustration with PDF tools that treat documents as pixels on a page. Editing one line meant everything broke, and producing an accessible, tagged PDF meant hours of manual cleanup in Acrobat. ReflowPDF was built to solve both at once โ a real rendering engine that keeps genuine document structure, so editing behaves like a word processor and accessible export comes out clean by default.
