CHOOSE WHAT YOU WANT TO CHANGE

Free PDF editor online.

Add text, fill existing form fields, sign and arrange pages in your browser. Choose an editing task below; your document is processed on your device without a document upload.

Check what this editor can do: these tools add text, fill supported existing fields, add marks or change pages. Replacing existing text and secure redaction are unavailable. Cropping or covering information does not securely remove it.

PDF files support up to 100 MB each. Device memory and individual tool limits still apply. Download an edited copy; your original file is not overwritten.

Text and forms

Fill PDF forms

Complete fields already in the PDF

Fill supported text fields, checkboxes and choices, then save an editable or flattened copy. Requires an existing standard PDF form; it does not create fields or fill a flat scan automatically.

Page layout

Crop PDF

Trim visible page margins

Trim the same percentage from every edge of every page. Cropping changes the visible area; content outside it remains in the file. It is not secure redaction.

Page layout

Rotate PDF

Turn sideways pages upright

Rotate all pages by 90, 180 or 270 degrees. Use this when the whole document needs the same rotation; individual-page rotation is not available here.

Page layout

Delete pages

Remove unwanted whole pages

Select page thumbnails or enter a page range to delete. The remaining pages keep their original order, and at least one page must stay in the document.

Reorder pages

Put pages in the right order

Drag thumbnails, use the move arrows or enter a page order. Every page stays included exactly once; use Delete pages when you need to remove one.

Number pages

Add a sequence of page numbers

Number every page at the bottom centre, starting at a number you choose. Numbers use a fixed size and position, without custom prefixes or page ranges.

Document details

Edit PDF details

Update the document title and details

Set or clear the PDF title, author and subject. This changes those document properties; it does not edit page text or remove every kind of metadata.

Choose the right kind of edit

Adding a name, date or answer?

Use Fill PDF forms when the document already has interactive fields. For a flat page without fields, Add text places a visible label where you need it. It does not turn the page into an interactive form.

Changing the words already on the page?

Edit the original Word or other source document when you have it. Otherwise, PDF to Word can extract selectable text into an editable DOCX; check the reading order and layout. For a scan, run OCR PDF first and review the recognized words. Use Word to PDF when the edited document is ready. See all conversion options →

Organizing the document?

Choose Delete pages or Reorder pages above for whole-page changes. To join documents, use Merge PDF; to extract pages or divide a file into parts, use Split PDF. Cropping only changes what is visible on a page.

Finishing a document to share?

Review the downloaded PDF before sending it, including page order, form values and the position of added marks. If an opening password is needed, finish your edits and then use Protect PDF. Document processing happens in the browser; read the privacy explanation for how the website and downloaded files are handled.

PDF editing questions

Can I change existing PDF text?

Add text places a new label; it cannot replace, delete or reformat existing words. Fill PDF forms changes supported fields that already exist in a form. For broader text changes, edit the original source document or review an editable conversion.

Are my PDFs uploaded, and do I need an account?

You do not need an account to use these editing tools. Selected documents are processed in your browser without a document upload. Your browser still downloads the application from this website; the privacy page explains ordinary website request data.

Can I sign a PDF here?

Yes. Draw a signature or type your name, then place its image on selected pages. This creates a visual mark, not a certificate-based digital signature. Editing a PDF that already has a certificate signature can invalidate that signature.

Does cropping or covering text securely redact it?

No. Cropping hides content outside the visible area, and added text or marks can cover content without removing it. Secure redaction is not available in these tools. Do not use them to erase sensitive information from a PDF.

Why can’t I fill some PDF forms?

The form filler supports existing standard AcroForm fields. Flat scans and XFA forms are not supported, and read-only or unsupported fields remain unchanged. Use Add text for a visible label on a flat page; OCR can recognize scanned words but does not create interactive form fields.
