PDF Editor — Edit, Design & Annotate PDFs Free guide

A complete PDF studio in your browser: open any PDF and edit it visually — select and change the PDF’s own text and images, add text, shapes, drawings, highlights and signatures, rearrange pages, merge files — or design a document from templates (certificate, invoice, poster, resume, flyer, social post) and export a finished PDF.

How to use this tool

  1. Open a PDF with the file button or drag it onto the panel — or choose Create new, pick a page size (A4, Letter, presentation, Instagram post or story), or load a design template. Nothing is uploaded; the file opens on your device.
  2. Work page by page on the canvas: with the Select tool, click anything on the page — objects you added, and the PDF’s own text and images (shown with faint outlines) — to move, restyle, edit, replace or remove them from the Properties panel. Or pick a tool on the left — Text, Image, Draw, Highlight, shapes, Whiteout, Sign, QR code — and click or drag on a page. Convert to outlines turns any selected text — one line, or a Shift-selected batch converted together — into true vector shapes traced from the PDF’s own embedded font whenever the file carries one.
  3. Manage the document from the Pages panel: rotate, duplicate, reorder or delete pages, insert blanks, and merge in whole extra PDFs with Add PDF. Undo and redo (Ctrl+Z / Ctrl+Shift+Z) cover every change.
  4. Use the Page & Export panel for a watermark and page numbers on all pages, then set a file name, optionally tick Protect with password, and click Export PDF to download the finished document.

A worked example

A tenant receives a rental agreement as a PDF, opens it here, fills in the date with the Text tool, draws a signature in the Sign pad and stamps it on the last page, adds a page-number footer for the printed copy, and exports a protected PDF — one page open in one tab, no printer, no scanner, no separate apps for each step.

What you can do with this tool

How it works

The studio renders each page with a PDF viewer engine in your browser and keeps your additions as objects — text boxes, images, shapes and pen strokes — positioned in true page points, so what you see is what exports. The same engine also maps the page’s original content: every line of existing text and every embedded image is located, so the Select tool can pick them up. Changing an original never rewrites the PDF’s content stream — your edit is drawn over the original and baked in when the document is rebuilt on export: original pages are copied losslessly, your objects are drawn onto them in order, watermark and page numbers are stamped across all pages, and optional password protection re-encrypts the result with the open-source QPDF engine. Design fonts (Montserrat, Playfair Display, Dancing Script — all open-licensed) are embedded into the export so your document looks the same everywhere. When a PDF’s own font is not embedded in the file, the studio looks the typeface up in the site’s shared font library — more than 2,300 real font files — before falling back to a public equivalent, which it adds automatically, so existing text keeps its own typeface wherever a copy of that font exists. The studio also detects fillable forms when a PDF opens, and can add new fillable fields of its own. Text you add can be highlighted in colour ranges — pick the words with the text editor’s highlighter or the Highlight text tool, and the tint (with a slightly darker outline) exports with the document. Image boxes work like photo frames: draw a rectangle, rounded or circular frame, drop in a picture, and it is cover-fitted and clipped to the frame shape in the export too — double-click the frame to drag the photo into position. Text boxes are drawn first and typed into afterwards: the words wrap inside the box and reflow when you resize it, which makes them the right choice for addresses, terms and other blocks of copy. Every PDF the studio exports carries an embedded copy of the editable project, so reopening it here restores every object and field as fully editable (the file is somewhat larger for it).

Frequently asked questions

Is my PDF uploaded to a server?

No. Opening, editing, designing and exporting all happen in your browser tab — the file, your signature and any password you set never leave your device, and closing the tab wipes everything.

Can I edit the text that is already in my PDF?

Yes — with limits. Click the line with the Select tool and choose Edit text: the studio covers the original line and drops in an editable text box with the same words at about the same size, ready to retype. It is a cover-and-replace, not true in-place editing — the original characters are not reflowed, and the covered text remains underneath the cover. If the underlying text must actually be removed, use our Redact PDF tool.

Can I remove or replace a logo or image that is part of the PDF?

Yes. With the Select tool, click the image (original images show a faint outline on the page) and choose Delete to cover it, Replace image to fit a new picture into exactly the same space, or Move as copy to lift a movable copy you can drag elsewhere. As with text, removal is a cover that is baked in on export — the original image data remains under the cover, so use Redact PDF when content must be destroyed, not just hidden.

What can I create from scratch?

Anything the tools allow, on A4, Letter, landscape, presentation (16:9), Instagram post and story sizes — and six editable templates give you a head start: a certificate, an invoice, an event poster, a one-page resume, an Instagram post and a business flyer. Every template element is ordinary text or shapes, so you can change all of it.

Is the signature a legal e-signature?

It is a visual stamp — a picture of your signature placed on the page, like signing a printout. Many everyday agreements accept that, but it carries no certificate, identity check or tamper-proofing, so where a certified digital signature is required, use a dedicated signing service.

Can I merge more files into the document I am editing?

Yes — the Add PDF button in the Pages panel appends every page of another PDF to the current document, keeping your edits on the earlier pages. Reorder or delete the new pages from the same panel.

Which fonts can I use, and do they travel with the file?

Three sources, and everything used is embedded into the exported PDF, so the document looks the same on any device. (1) The standard PDF families (Helvetica, Times, Courier) and the three design fonts — Montserrat, Playfair Display and Dancing Script, all open-licensed. (2) More than 130 Google Fonts in the Properties font menu — search by name and the family loads on demand. (3) The site’s shared font library of 2,300+ real font files: when a PDF’s text uses a font that is not embedded in the file, the studio checks this library first and uses the genuine font when it is there; if it is not, a public equivalent is added automatically (Century becomes Spectral; Georgia becomes Gelasio, its metric clone, so the layout does not shift). You can also add your own fonts from the font menu and choose to share them into the same library.

Can I convert text to vector outlines?

Yes. Click the text with the Select tool and choose Convert to outlines — or Shift-click several texts and convert them together from the multi-selection panel, which is a single Undo step. The letters become true vector shapes that you can move, resize and recolour like any shape; they are no longer editable as text, and Undo brings the text back. Whenever the PDF carries its font embedded, the outlines are traced from that embedded font, so the letter shapes are the original ones; otherwise the closest library font is used and the status line says so.

Can I add clickable links to a PDF?

Yes. Select any text or image — one you added or the PDF’s own — and set a Link in the Properties panel: a web address, an email (it becomes a mailto link) or a phone number (a tap-to-call tel link). The exported PDF carries a real clickable link over that item’s area. On the PDF’s own content the link attaches to an editable copy of the item, so it always travels with it.

Can I resize text by dragging?

Yes. Drag the left or right handle to change the box width — the text re-wraps at the same size. Drag a corner handle to scale the text itself: the font grows or shrinks with the drag, no size value to type.
