The Online PDF Editor
That Never Uploads Your Documents
A practical walkthrough of building, annotating, and exporting multi-page PDFs entirely in your browser plus the honest trade-offs behind that architecture.
1Start Your Document
Open the Page tab and pick a starting point: one of four pre-filled templates (Contract, Offer Letter, Memo, Proposal), a blank page, or your own imported image background. To combine several source files into one document, use the Pages tab's "Images → Pages" or "Merge / Import PDF as Pages" buttons each file you add becomes a new page, appended to your working document in order.
Every page carries its own background, size, and filter settings independently, so a document can mix a template cover page with scanned image pages without any conflict.
2Annotate Text, Stamps, Signatures, Marks
Switch tools from the Tools tab: Text for headings and body copy, Stamp for six certification types (APPROVED, CONFIDENTIAL, DRAFT, SIGNATURE, VOID, COPY), Sign for a freehand signature, and Highlight, Underline, or Strikethrough for marking up existing text drag across the region you want to mark.
Everything placed on the canvas stays draggable afterward using the Select tool, and can be deleted instantly with the Delete key or the trash icon that appears once something is selected.
3Build a Multi-Page Document
The Pages tab handles multi-page editing: add blank pages, duplicate an existing page as a starting point for the next one, reorder with the up/down arrows, or delete pages you no longer need. Check the box on any page to include it in a partial export useful for splitting a large document down to only the pages a specific recipient actually needs.
4Watermark, Then Export a Real Multi-Page PDF
The Watermark tab stamps a diagonal, semi-transparent label "CONFIDENTIAL," "DRAFT," your company name across every page at once, with control over size, opacity, angle, and color, previewed live as you adjust it.
Pick a quality preset in the top bar Web/Email for the smallest file, Print for everyday office use, or Press/High-Res for professional print quality then click Export Full PDF. Every page is flattened and assembled into one genuine multi-page PDF using the pdf-lib library, running entirely in your browser. No upload, no processing queue, no watermark added by the tool itself.
5Why 100% Local Processing Actually Matters
Most online PDF editors upload your document to a remote server, process it there, and send a result back. Every file annotated that way contracts, offer letters, signed agreements passes through infrastructure you don't control, for a retention window you can't verify.
This editor's rendering pipeline runs entirely on the Canvas API inside your browser tab. Placing a stamp, drawing a signature, merging in another PDF's pages, or exporting the final file all execute on your own device's memory and CPU there is no upload step, because the document never leaves the tab it's open in. This matters most for the documents people actually edit: employment contracts, NDAs, signed agreements, ID scans, and financial statements. For real password encryption after editing, pair this with ToolMany's dedicated PDF Lock tool, which applies genuine AES-256 encryption via the browser's native Web Crypto API something pdf-lib itself cannot do.

7Best Use Cases
Freelancers & small businesses
Build contracts, offer letters, and proposals from the built-in templates, then stamp and sign without leaving the browser.
Students
Merge scanned assignment pages, highlight a reading, and export one clean multi-page PDF for submission.
HR & legal teams
Draft and stamp internal memos and offer letters, watermark drafts CONFIDENTIAL, then hand off to PDF Lock for real encryption before sending externally.
Agencies & consultants
Assemble project proposals from the proposal template, merge in supporting scanned documents, and export a polished, print-ready package.
8Best Practices for Professional Documents
Consistent typography
One or two font families, bold for headings, italic sparingly for dates or reference lines.
Stamp placement discipline
Top-right corner for formal documents, directly above the signature zone for approvals.
Export at Print or Press for anything printed
Web/Email quality is fine for screens but looks soft once printed on paper.
Use page selection for splitting
Check only the pages a recipient needs before exporting, instead of sending the whole working document.
Layer on encryption when needed
Export here, then password-protect with PDF Lock for anything sensitive before sending it out.
Use keyboard shortcuts to move faster
Delete removes a selection instantly, Ctrl+Z undoes a stray pen stroke without breaking flow.
