About Word Editor
Open a Word document, edit it, save it — without leaving your browser and without your file ever touching a server. SnapToolz parses your .docx into a structured document model (paragraphs, headings, lists, bold/italic/underline runs), renders it as editable HTML inside a contentEditable surface, and lets you format with a familiar toolbar. On save, your edits are walked back out to a fresh OOXML .docx that opens in Microsoft Word, Google Docs, LibreOffice or Apple Pages. The honest scope is text + structure + light formatting — not a pixel-perfect Word clone. For documents that lean on tables, embedded images, or specific page layout, Microsoft Word remains the right tool.

Frequently asked questions
Are my files uploaded to a server?
No. Every tool on SnapToolz runs entirely inside your browser using JavaScript and WebAssembly. Your file is read locally, processed in memory, and the result is offered as a download. Nothing is sent to a server — there isn't one to send to.
What's preserved through the round-trip?
Plain paragraphs, heading levels (H1-H6), bold/italic/underline runs (mixed within a paragraph), bulleted and numbered lists, and hard page breaks. Output uses one chosen base font (Calibri / Arial / Times Roman / Georgia) at one configurable size.
What's lost on save?
Tables, embedded images, hyperlink URLs (visible link text survives), custom fonts/colours/sizes per run, headers/footers, sections/columns, tracked changes, and comments. v1 is intentionally a focused text+structure editor; for those features the right tool is still Microsoft Word.
Why no tables in the editor?
Real WYSIWYG table editing in the browser requires resize handles, cell merging, column-width drag, and complex selection logic — that's hundreds of lines of UI code on its own. v1 is honest about its scope: text content and structure. Tables in the source flatten to plain paragraphs (their cell text survives but the grid is lost).
How does this compare to Google Docs or Word Online?
Those are full WYSIWYG editors with tables, images, comments, and collaboration. They also send your document to a server. SnapToolz is small, focused, and 100% local. If your document is text + headings + lists, the Word Editor is faster and more private. If it has tables/images that matter, use a full editor.
Will Microsoft Word open the saved file?
Yes. The output is a standards-compliant OOXML .docx with the four required parts ([Content_Types], _rels, document.xml, with the right MIME types). Tested in Word, Google Docs, LibreOffice Writer, and Apple Pages.
Can I open a file I just saved here back in this editor?
Yes, fully — the round-trip preserves everything we emit. Headings, lists, run styles, page breaks all survive saving and reopening.
Does it work offline?
Yes. SnapToolz is a Progressive Web App. After your first visit, the app is cached on your device and every tool keeps working without an internet connection.
Is SnapToolz free?
Yes — every tool is 100% free with no sign-up, no watermark, no hidden tier. The whole platform is open source and we have no plan to gate features.
