Free PDF Editor — Edit, Sign, Annotate & Organize PDFs in Your Browser

Merge, reorder, rotate and split pages; add text, images, shapes, highlights and signatures; fill forms, erase content, add watermarks and page numbers — then download. 100% in your browser: no upload, no signup.

This free PDF editor lets you reorganize, annotate, sign, and fill PDF documents directly in your browser — no upload, no signup, and no watermark on the result. Drop a PDF onto the tool above and you can merge several files into one, drag pages into any order, rotate or delete them, add text, images, shapes and signatures, drop in a watermark or page numbers, fill out form fields, and export a finished PDF. Everything happens on your own device: the file is parsed and rebuilt locally with open-source libraries, so a tax return, a signed contract, or an internal report never leaves your computer. You can even disconnect from the internet once this page has loaded and keep editing.

What you can do with this PDF editor

Most “edit PDF” needs fall into four buckets, and this editor covers all of them in one place:

  • Organize pages — merge multiple PDFs into one, reorder by dragging thumbnails, rotate, delete, duplicate, insert blank pages, and extract or split pages into separate files.
  • Annotate — add text boxes, images, rectangles, ellipses, lines, freehand pen strokes, highlights and signatures anywhere on a page, then move, resize and rotate them freely.
  • Layers & layout — a layers panel lists every object on a page so you can reorder, hide, lock and align them, with undo/redo and keyboard shortcuts.
  • Fill forms — open a fillable PDF and type into its real form fields, then download a flattened copy.

How to merge and reorder PDF pages

Combining and reordering pages is the most common PDF editing task, and it is the heart of this tool. A worked example: say you scanned a three-page contract but the pages came out in the wrong order, and you also want to append a cover letter that lives in a separate PDF.

  1. Add both PDFs. Drop the contract and the cover letter onto the editor. Their pages appear together in the left-hand page rail, merged into a single document.
  2. Reorder. Drag a page thumbnail to a new position, or use the up/down buttons on each thumbnail if you prefer the keyboard. Put the cover letter first, then the contract pages in the right sequence.
  3. Fix orientation. If a scanned page is sideways, select it and click Rotate until it is upright. The editor composes your rotation with the page’s existing orientation so it always looks right.
  4. Export. Click Download PDF and you get one clean, correctly-ordered document.

Every change is undoable — there is no destructive “save over the original,” because the original never leaves your machine in the first place. If you only need to turn PDF pages into images rather than edit them, our PDF to PNG and PDF to JPG converters do that in the same private, in-browser way.

How to add text, images, and a signature to a PDF

The annotate tools turn this from a page organizer into a true PDF editor. Pick a tool from the toolbar and click on the page to place an object; everything you add can be dragged, resized from its corners, and rotated. A common example is filling and signing a PDF that is not a “real” form — a printout you were emailed, say:

  1. Add text. Click the Text tool, then type your name, a date, or any answer directly onto the blank line. Adjust the font size, color and alignment in the properties panel on the right.
  2. Add a checkmark or initials. Use the Pen tool to draw a check or your initials by hand, or drop a shape onto a checkbox.
  3. Sign it. The Sign tool lets you draw a signature with the pen or type one in a script font, then place and resize it over the signature line.
  4. Add an image. Insert a logo, a photo of a wet signature, or a stamp, and scale it to fit.

When you export, the original PDF text stays fully selectable and searchable; the annotations you added are stamped onto each page as a crisp, high-resolution layer, so the result looks exactly the way you arranged it on screen. This “what you see is what you get” approach avoids the misaligned-text problems that plague many online PDF editors.

How to split or extract pages from a PDF

Sometimes you need fewer pages, not more. To pull a few pages out of a long PDF, select them — Shift- or Ctrl-click their thumbnails, or type a range like 1-3,5 in the side panel — and click Extract to download just those pages as a new PDF. To break a document into individual files, click Split: every page (or just your selected pages) is saved as its own single-page PDF, bundled together in one ZIP so you can download them all at once. This is the fast way to separate a merged scan back into individual documents, or to send someone only the page they actually need.

How to fill out a fillable PDF form

If your PDF contains real form fields — an application, a tax form, an intake sheet — open it on its own and the side panel automatically lists every field it finds. Type into text fields, tick checkboxes, and choose from dropdowns, then click Download filled form (flattened). The editor fills the fields and flattens them so the answers become a permanent part of the page, which means the filled PDF looks identical everywhere and cannot be accidentally edited by the next person who opens it. If a form uses Adobe’s older XFA “dynamic” technology, the editor will tell you, since those forms behave differently. And remember: even a PDF with no real fields can still be “filled” visually with the Text and Pen tools described above.

Watermarks, page numbers, and the layers panel

Beyond per-page objects, the editor offers document-wide touches. Turn on a diagonal watermark (“CONFIDENTIAL”, “DRAFT”, or your own text) and set its opacity; switch on automatic page numbers and choose the format (1, Page 1, or 1 / N). Both are applied across the document at export. For finer control, the layers panel shows every object on the current page in stacking order — click to select, use the eye to hide, the lock to protect an object from accidental edits, and the arrows to send it forward or back. Multi-select several objects to align or evenly distribute them. Keyboard shortcuts speed everything up: undo and redo, duplicate, delete, arrow-key nudging, and bring-forward / send-backward all work as you would expect in a graphics editor.

Edit a PDF in your browser — why no upload matters

Almost every “free online PDF editor” uploads your document to a server, edits it there, and sends it back. For a flyer that is fine. For anything with personal or commercial information — contracts, IDs, bank statements, medical forms, HR documents — handing the file to a remote machine is a genuine privacy risk, and many of those services keep your file for hours or quietly reserve the right to. This PDF editor is different: it runs entirely as JavaScript in your browser. The PDF is read into memory locally, edited locally, and rebuilt locally; nothing is transmitted, nothing is logged, and there is no account to create. You can verify it yourself — open your browser’s Network tab while you edit and export a PDF, and you will see no file being uploaded. The heavy libraries that power the editor load only after you add your first file, so the page itself stays fast.

What is preserved when you export

Honesty about the output matters. Reordering, rotating, deleting, duplicating and merging copy your original pages as-is, so text and images keep their original quality and the underlying text stays selectable. Annotations you add are baked onto the page as a sharp image layer. Two things to know: internal cross-page links and the bookmark/outline panel are not carried into a rebuilt, reassembled document (the page content itself is fully preserved); and external web and email links inside the original pages do survive. For the vast majority of editing tasks — combine, reorder, sign, fill, annotate, export — the result is exactly what you intend.

A PDF editor that works on any device

Because this PDF editor is just a web page, it runs anywhere a modern browser does — Windows, macOS, Linux, Chromebooks, iPhone and Android — with nothing to install and nothing to update. On phones and small screens the page rail and tools collapse into slide-in panels so the page you are editing stays front and centre, and you can pinch and drag objects with touch. There is no desktop app, no browser extension, and no operating-system requirement: if you can open this page, you can edit your PDF. That also makes it a safe choice on a shared or work computer, where installing software is often not allowed — the PDF editor leaves no trace because there is nothing to install and no file ever leaves the machine.

Free, no signup, no watermark

There is no account, no daily limit, no premium tier, and no watermark stamped on your file — the editor is yours to use as much as you want. If your task is really about converting rather than editing, the matching in-browser converters handle that: PDF to PNG, PDF to JPG, PDF to WebP, PDF to AVIF, and PDF to TIFF. They all work the same way this PDF editor does: privately, in your browser, with no upload.

Frequently Asked Questions

Are my PDF files uploaded to a server?
No. The editor runs entirely in your browser — your files never leave your device. There is no upload and no signup.
Does it change the quality of my PDF?
Reordering, rotating, deleting and merging copy your original pages as-is — text and images keep their original quality. Internal bookmarks and cross-page links are not carried into the rebuilt file.
Can I merge several PDFs into one?
Yes. Add multiple PDFs and they combine into one document you can reorder and export.
Can I reorder, rotate or delete pages?
Yes — drag thumbnails (or use the Move up/down buttons), rotate in 90° steps, delete, and duplicate pages. Undo reverses any change.
Can I split a PDF into separate files?
Yes. Split downloads each page (or your selected pages) as separate PDFs bundled in a ZIP.
Does it work with password-protected PDFs?
No. Remove the password in your PDF reader first, then load the file here.
Is there a file size limit?
Because everything runs in your browser, very large files depend on your device's memory. Files up to ~50 MB work smoothly on most machines; larger ones may be slower, especially on phones.
Does it work on mobile?
Yes. The page rail and tools become slide-in panels on small screens, and the canvas stays front and center.
Can I add text, images, or a signature to a PDF?
Yes. Use the toolbar to add text boxes, images, shapes, highlights, freehand drawing, and signatures, then drag, resize, and rotate them anywhere on the page.
Can I add a watermark or page numbers?
Yes. Turn on a diagonal watermark or automatic page numbers in the side panel; they apply across the document and you can choose the format.
Will my added text stay selectable in the exported PDF?
The original PDF text stays fully selectable. Annotations you add are stamped onto the page as a crisp high-resolution layer, so they look exactly as you placed them.
Can I manage objects in layers and use keyboard shortcuts?
Yes. The Layers panel lists every object on a page so you can reorder, hide, lock, or delete them, and you can align or distribute a selection. Keyboard shortcuts include undo/redo, duplicate, delete, arrow-key nudging, and bring-forward / send-backward.
Can I fill out a fillable PDF form?
Yes. Open a single PDF that has form fields and the side panel lists them — type or choose your answers, then download a filled, flattened copy. You can also fill any PDF visually by typing text and adding checkmarks with the annotation tools.
