Open any PDF and do the things you came here for: rotate, reorder, delete, merge, split, annotate, sign, watermark, number pages, tweak metadata, and lock or unlock with a password. Everything happens in your browser — your file never leaves your device — and every change is undoable.
Drop a PDF here or click to browse
Everything runs locally in your browser — your file never leaves your device.
Page-level controls, content annotations, global enhancements, and document metadata — all from one clean toolbar. No sign-ups, no watermarks on output, no quotas.
Rotate pages 90° in either direction, reorder by drag-and-drop, delete single pages or selected batches, and duplicate pages with one click.
Merge another PDF at the end of your document, or insert a blank A4 page at any point in the sequence.
Check the pages you want to keep, click 'Extract', and download them as a brand-new PDF — the original stays untouched.
Click-to-place any annotation. Add free text with custom size/color, drop in any image, or draw a live signature and stamp it where you want.
Apply a text watermark to every page. Pick color, size, opacity, rotation, and one of five positions — center (rotated) or any corner.
Auto-add page numbers with a custom format (Page {'{n}'} of {'{total}'}), any position, color, font size, and starting offset.
Set title, author, subject, and keywords — or wipe them entirely for privacy before sharing externally.
AES-128 encrypt your PDF with a user password and fine-grained permissions (print, modify, copy, annotate). All done locally.
Open a password-protected PDF, enter the password once, and save a permission-free copy. The password never leaves your device.
Every operation snapshots into a 30-step history. Mistakes are never fatal. Ctrl/Cmd+Z to undo, Ctrl/Cmd+Y to redo.
The editor loads and saves PDFs entirely in your browser using WebAssembly. Nothing is uploaded, nothing is logged.
Drag a file onto the upload zone or click to browse. The editor parses it locally — nothing is uploaded.
Rotate, reorder, delete, duplicate, or add new blank pages. Select any combination of pages for batch actions.
Click-to-place text, images, or a drawn signature. Apply watermarks or page numbers across all pages in one click.
Hit 'Download' to save your edited PDF. Original metadata is preserved unless you chose to modify or clear it.
No. The editor runs 100% in your browser using pdf-lib and pdf.js. Nothing is sent to any server.
Yes. Open one PDF, then click 'Merge PDF' and select a second file — its pages are appended to the end of the current document.
Yes. Tick the checkbox on each page thumbnail you want to keep, then click 'Extract (N)' to download just those pages as a new PDF.
Yes. Click 'Signature', draw with your mouse or finger, then click on the page where you want it placed. You can also use 'Add Image' to stamp a pre-made signature image.
Yes. Click 'Lock' in the toolbar, enter a user password and optional owner password, pick which permissions you want to allow (print, modify, copy, annotate), and download the AES-128 encrypted PDF. All encryption happens in your browser.
Yes. Open any password-protected PDF — the editor detects the password requirement and prompts for it. Once unlocked, click 'Unlock' in the toolbar to save a permission-free copy. Your password stays on your device.
Yes. The layout adapts to small screens and touch input. Drawing signatures, placing annotations, and drag-to-reorder all work on mobile browsers.

Browser-based PDF tools have transformed how people work with documents. Unlike expensive desktop software that requires installation, updates, and licensing fees, online PDF tools are available instantly on any device with a web browser — no setup, no account required. Modern web technologies like WebAssembly allow these tools to process complex PDF operations at near-native speed, entirely within your browser.
Privacy is the defining advantage. Every PDF operation runs locally on your device using JavaScript and WebAssembly. Your files never travel to any server, never sit in cloud storage, and are never processed by third-party infrastructure. When you close the browser tab, all temporary data is automatically cleared. This makes browser-based PDF tools safe to use with confidential business documents, legal files, medical records, and personal information.
The PDF format was designed for fixed-layout document exchange — text, images, and graphics placed at precise coordinates on a page. Understanding this helps set accurate expectations: PDF tools excel at annotation, form filling, signing, merging, splitting, compressing, and converting. For substantial content rewrites, working in the source format (Word, Google Docs) and re-exporting as PDF produces the cleanest results.
Yes — completely. Every operation runs entirely in your browser. Your files never leave your device and are never transmitted to any server. When you close the browser tab or navigate away, all temporary data is automatically cleared from memory. This makes it safe to use with any confidential, sensitive, or proprietary documents.
A native PDF was created digitally from a word processor, design tool, or export function and contains actual searchable text data. A scanned PDF is a photograph of a physical page stored inside a PDF container — it contains no text data, only pixels. Most PDF editing and annotation features work on both types, but features that require reading underlying text (like click-to-edit or text highlighting) only work reliably on native PDFs.
PDF file size is primarily determined by embedded images. Compression tools re-encode images at a lower quality setting and remove redundant metadata, embedded thumbnails, and duplicate resources. For scanned documents with high-resolution images, compression ratios of 60–80% are common with no perceptible quality loss on screen. For text-heavy PDFs, file sizes are already small and compression gains are modest.
Directly replacing existing text is technically possible but difficult in practice. The PDF format stores each character at a specific position — replacing one word with a longer word requires recalculating every subsequent character's position. Most browser-based PDF tools handle this with text overlay: place a white rectangle over text you want to change and add a new text box on top with corrected content. For major content rewrites, editing in the source format and re-exporting as PDF produces cleaner results.
Yes. Browser-based PDF tools work on any device with a modern web browser — smartphone, tablet, laptop, or desktop. The interface adapts to touch input for drawing signatures, placing annotations, and navigating pages. For large PDF files, a device with more RAM will provide smoother performance, but most everyday documents work well even on mid-range smartphones.
