Everything you'd expect — and more

A full editing toolset that runs entirely in your browser. No installs, no plugins, no waiting.

Add & Edit Text

Type new text anywhere or click existing paragraphs to edit in place — font, size, color and alignment all adjust automatically.

Images & Shapes

Insert JPG/PNG/SVG/WebP images, replace existing ones, or draw rectangles, circles, lines and arrows with snap-to-grid.

Hyperlinks

Link any text or shape to an external URL or jump to another page inside the same document.

Headers, Footers & Page Numbers

Add running headers, footers and custom-format page numbers — apply to all pages or specific ranges.

Watermark & Background

Stamp a text or image watermark on every page and edit page background colors or images.

Full Page Management

Add, delete, duplicate, rotate, crop, resize, extract, split or merge pages with drag-and-drop reordering.

Annotate & Markup

Highlight, underline, strike-through, freehand draw, sticky notes, comments with mentions and replies.

Stamps & Approvals

Drop preset stamps like Approved, Draft, Confidential — or create your own reusable stamps.

Real-time Collaboration

Edit and comment with teammates live. See cursors, replies, @mentions and a full version history.

Compare PDFs

Diff two versions of a document side-by-side and visually highlight every text, layout and image change.

Fillable Forms

Auto-detect or manually add text fields, checkboxes, radio buttons, dropdowns and date pickers. Validate and export data as JSON or CSV.

E-Signatures

Draw, type or upload a signature. Send for multi-party signing via email and track status in real time.

OCR for Scanned PDFs

Convert scanned pages or images into searchable, editable text in 50+ languages while preserving layout.

Redact Sensitive Info

Permanently remove text, images or full areas — content is stripped from the file, not just hidden.

Security & Permissions

Add digital certificates, set view/edit/print permissions and share via password-protected, expiring links.

Auto-save to Dashboard

Every edit is auto-saved to your dashboard. Open multiple files in tabs, undo/redo without limits, and pick up where you left off on any device.
