Step-by-Step Guide to Editing PDFs
Step 1: Upload Your PDF
Drag and drop your PDF file into the upload area, or click the "Select PDF" button to browse your computer. The file loads instantly in your browser without uploading to any server.
Step 2: Choose Your Editing Tool
Select from the toolbar on the left: text tool for adding words, highlight for marking important areas, shapes for annotations, or freehand drawing for signatures and notes.
Step 3: Make Your Edits
Click anywhere on the PDF page to add your annotations. Use the color picker to change colors, adjust font sizes for text, and navigate between pages using the controls.
Step 4: Save and Download
When finished, click "Save & Download" to generate your edited PDF. All annotations are permanently embedded in the document for sharing or printing.
Add Text Annotations
Insert text anywhere on your PDF pages. Customize font size from 8px to 72px and choose from multiple colors. Perfect for adding comments, notes, or filling in forms.
Highlight Text
Draw transparent highlight boxes over important text or sections. Choose from yellow, green, blue, pink, and other colors to organize your highlights by category.
Draw Shapes
Add rectangles and circles to emphasize areas or create visual annotations. Use shapes to circle important information or create boxes around sections.
Freehand Drawing
Draw freely on your PDF with the pencil tool. Ideal for adding handwritten signatures, underlining text, drawing arrows, or making quick sketches and marks.
Rotate Pages
Rotate individual pages clockwise or counterclockwise in 90-degree increments. Fix scanned documents that were captured at the wrong orientation.
Delete Pages
Remove unwanted pages from your PDF document. Deleted pages can be restored before saving if you change your mind. Streamline documents by removing blank or unnecessary pages.
Contract and Document Annotation
Review contracts, proposals, and business documents by adding comments, highlighting key terms, and marking sections that need attention. Share annotated PDFs with colleagues for collaborative review without expensive software subscriptions.
Student Study Materials
Highlight textbook PDFs, add notes to lecture slides, and annotate research papers. Use different highlight colors to categorize information by topic or importance. Create study guides by marking key concepts and adding your own explanations.
Fill Out PDF Forms
Add text to non-fillable PDF forms, applications, and documents. Type your information directly onto the form fields, add your signature using the freehand tool, and download the completed form ready for submission.
Legal Document Review
Mark up legal documents for review, highlight important clauses, and add margin notes. Use shapes to circle signature lines and draw attention to dates and terms. Rotate and remove pages to prepare documents for filing.
Use Zoom for Precision
Zoom in to 150% or 200% when adding small text or detailed annotations. This gives you more precise control over placement and makes it easier to work with complex documents.
Color-Code Your Annotations
Use different colors for different purposes: yellow for general highlights, red for urgent items, green for completed tasks, and blue for questions or follow-ups.
Undo Mistakes Instantly
Made an error? Use the Undo button to reverse your last action. You can undo multiple steps and redo them if needed. This makes experimentation risk-free.
Select and Delete Annotations
Switch to the Select tool to click on any annotation. Once selected, use the Delete Selection button to remove it. This is faster than using Undo for older changes.
Is this PDF editor really free?
Yes, our PDF editor is completely free to use with no limitations. There are no watermarks added to your documents, no file size limits, and no restrictions on the number of pages you can edit. You can use all features without creating an account.
Are my PDF files secure and private?
Absolutely. Your PDF files never leave your computer. All processing happens entirely within your web browser using JavaScript. We do not upload, store, or have access to any of your documents. This makes our editor one of the most secure options available.
Can I edit text that is already in the PDF?
This editor focuses on adding annotations, text overlays, and shapes to PDFs. It does not modify the original text content of the PDF. To add new text, use the Text tool to place text boxes anywhere on the page. For editing existing text, you would need a full PDF editing suite like Adobe Acrobat.
What browsers are supported?
Our PDF editor works in all modern web browsers including Google Chrome, Mozilla Firefox, Microsoft Edge, Safari, and Opera. For the best experience, we recommend using the latest version of your preferred browser with JavaScript enabled.
Can I add my signature to a PDF?
Yes! Use the Freehand Drawing tool (pencil icon) to draw your signature directly on the PDF. Choose black or blue color for a professional look. Your signature will be permanently embedded in the PDF when you save and download the document.
How do I remove pages from a PDF?
Navigate to the page you want to remove using the page controls, then click the "Delete Page" button in the Page Actions section. The page will be marked for deletion. If you change your mind, you can restore it before saving. When you download the edited PDF, deleted pages will be permanently removed.
Why should I use an online PDF editor instead of desktop software?
Online PDF editors offer several advantages: no installation required, works on any device with a browser, always up-to-date, and accessible from anywhere. Our browser-based editor also provides better privacy since files never leave your device, unlike many cloud-based alternatives that upload your documents to their servers.
100% Client-Side Processing
ToolsGuru PDF Editor processes all files locally in your browser. Your documents are never uploaded to our servers or any third-party service. This approach ensures maximum privacy and security for sensitive documents including contracts, financial statements, medical records, and personal information. When you close the browser tab, all data is immediately cleared from memory with no trace left behind.
