How to Edit a PDF Online Free — Complete Guide

PdfPeaks is a free online PDF editor that lets you change text, highlight passages, draw annotations, erase content, and crop pages — without installing Adobe Acrobat or Microsoft Word. Click any paragraph to edit it with Word-like reflow: add or remove words and the text adjusts naturally. Ideal for contracts, forms, school assignments, and quick document fixes on Windows, Mac, Linux, and mobile browsers.

How It Works

Upload your PDF, edit directly in the browser, then save and download the updated file. The editor detects paragraphs automatically so you can click and type instead of placing boxes manually.

• Step 1 — Upload: Drag and drop your PDF or click Choose PDF. Digital and scanned documents are supported.
• Step 2 — Edit text: Stay in Select mode and click a paragraph. Type to change words — text reflows within the paragraph like Microsoft Word.
• Step 3 — Add content: Use Add Text for new labels, Annotate for highlights and drawings, or Erase to white-out unwanted areas.
• Step 4 — Save: Click Save to apply all changes to the PDF and download the finished file.

Edit PDF Text Like Microsoft Word

Unlike basic PDF viewers, PdfPeaks treats each paragraph as an editable text block:

• Click to edit: Select mode + click any line or paragraph. The original text is hidden and replaced with an editable field.
• Natural reflow: Adding or removing words pushes surrounding text within the paragraph — no overlapping lines.
• Matching fonts: Font size and family are detected from your document (Arial, Times New Roman, Helvetica, and more).
• Undo: Press Ctrl+Z (or Cmd+Z on Mac) to undo text, annotations, or erasures.
• Scanned PDFs: For image-only scans, use Form Fill to click and type anywhere on the page, or Extract (OCR) to make text selectable first.

Annotation & Markup Tools

Beyond text editing, the toolbar includes professional markup tools similar to Smallpdf and Adobe Acrobat:

• Highlight: Drag over text to add semi-transparent yellow (or custom-color) highlights.
• Draw: Freehand pen for signatures, circles, and free-form notes.
• Shapes: Rectangles, ellipses, lines, and arrows for diagrams and feedback.
• Images: Insert PNG or JPG logos, stamps, or photos onto any page.
• Erase: Drag a rectangle to remove vector text and blank overlapping image pixels in that region on save.
• Crop: Trim page margins by drawing a crop region and clicking Apply.

Security & Privacy

Files are encrypted in transit and deleted after processing — see our Privacy Policy for details. Erase removes matching vector text and blanks overlapping image pixels in the erased region when the primary save pipeline runs. It is not a certified legal-redaction workflow — always verify the downloaded file (search and copy/paste) before sharing. Our Mask PDF tool only covers content with black boxes and does not permanently remove underlying text.

Common Use Cases

Students, freelancers, and teams use PdfPeaks PDF Editor for:

• Contracts: Fix typos, update dates, and fill missing fields before signing.
• Invoices & receipts: Correct amounts, add notes, or highlight line items for accounting.
• Education: Mark up readings, fill worksheets, and return annotated assignments.
• HR & forms: Complete PDF application forms without printing and scanning.
• Real estate: Add comments on floor plans and disclosure documents.
• Design review: Circle areas on proofs that need revision.

Tips for Best Results

Always click Save before closing the tab — live edits are previewed in the browser but only written to the PDF on save. For large text changes that grow a paragraph, you may need to drag blocks below it downward since PDFs use fixed page layout (unlike flowing Word documents). Do not rely on Mask PDF for permanent removal — it only covers content visually. Use Erase when you need content stripped from the region, then verify the output. Need a signature? Try Sign PDF. Supported format: PDF (.pdf).
