Built for controlled editing
One document. Four ways to work.
Move between visual editing, precise HTML, desktop Split and responsive Preview without creating disconnected copies.
Honest DOCX fidelity
Complex Word page layout, floating objects, headers, footers and text boxes may be simplified when converted into semantic HTML.
Inputs
HTML, pasted content and DOCX. HTML editing is limited to 5 MB; DOCX import is limited to 25 MB.
Outputs
HTML, self-contained HTML, website ZIP, genuine DOCX and plain text.
Editor modes
Visual, HTML, desktop Split and an isolated responsive Preview.
Safety model
Active content is removed and Preview uses a script-disabled sandbox with a restrictive content policy.
Cleaning capabilities
Word, Google Docs, website, WordPress, email, semantic and plain-text cleanup controls.
Import and export
Open local HTML or DOCX, manage extracted images, then export or save supported artifacts to Documents.
Difference from HTML to PDF
HTML Document Studio edits and cleans HTML. HTML to PDF renders finished HTML into a fixed-layout PDF.
Open HTML to PDFDifference from Word to PDF
DOCX import creates editable semantic HTML. Word to PDF converts a Word document directly into a PDF.

Frequently asked questions
Practical details about editing, cleaning, safety, DOCX fidelity and export behavior.
01Can I edit HTML without writing code?+
Yes. Visual mode provides headings, text formatting, lists, alignment, links, images, tables, colors and other common document controls while keeping HTML source available.
02Does Visual mode stay synchronized with HTML mode?+
Yes. Both modes work on the same document state. Updates are debounced to reduce cursor disruption, and Split mode lets you compare both representations.
03Can scripts run in the preview?+
No. Preview content is sanitized and rendered inside a sandboxed iframe without script permission, network connections or form submission.
04Can I open HTML and Microsoft Word files?+
Yes. Open local .html and .htm files up to 5 MB or import .docx files up to 25 MB. DOCX content is converted to semantic HTML before editing.
05What does DOCX import preserve?+
The converter preserves useful document semantics including headings, paragraphs, bold and italic text, lists, links, tables and embedded images. Advanced page layout, floating objects and Word-only effects may be simplified.
06Can I edit images extracted from a DOCX file?+
Yes. The image manager shows each image source and dimensions and lets you edit alt text, set display dimensions, replace, compress or remove the image.
07What export formats are available?+
Export a self-contained HTML document, a website ZIP with index.html and safe image paths, a genuine DOCX package, or plain TXT. Signed-in users can also save HTML, DOCX and ZIP artifacts to Nexynto Documents.
08Does it clean Microsoft Word or Google Docs formatting?+
The studio detects common rich-source signatures and offers an explicit Clean HTML action. It never silently removes formatting on paste.
09What does HTML validation check?+
The source editor reports unmatched, unexpectedly closed and unclosed tags with line numbers. Browser parsing and a sandboxed preview provide an additional practical review layer.
10Can I preview cleanup before changing my document?+
Yes. Every cleaning profile exposes its selected rules and generates a real before-and-after proposal with operation counts and byte-size differences before Apply Cleaning becomes available.
11Does email cleanup remove inline styles?+
No. The email profile is deliberately conservative because many email clients depend on inline presentation styles. Security sanitization remains a separate explicit control.
