Published by PDFCamel · 5 min read
Need to add a note, highlight important text, or cover sensitive information in a PDF? With PDFCamel's free online PDF editor, you can do all of that — directly in your browser, with no installation required. In this guide, we'll walk you through every tool available and how to use them effectively.
Why Edit PDF Online?
Traditional PDF editors like Adobe Acrobat can be expensive and require installation. Online PDF editors solve this by letting you edit documents instantly from any device — whether you're on a Windows PC, Mac, or even your smartphone.
PDFCamel's Edit PDF tool is completely free, works on mobile, and processes your file securely. Your document is never stored on our servers.
Step-by-Step: How to Edit PDF on PDFCamel
Upload Your PDF File
Go to PDFCamel Edit PDF. You can either drag and drop your PDF file into the upload area, or click the Select PDF File button to browse from your device. Your file will load instantly in the editor.
Choose Your Editing Tool
Once your PDF is loaded, you'll see a toolbar at the top with these tools:
Text
Add text annotations anywhere on the PDF. Type your text in the options panel, then click on the PDF to place it. Double-click an existing text to edit its content.
Draw
Freehand drawing tool. Choose your color and brush size, then draw directly on the PDF with your mouse or finger (on mobile).
Highlight
Add a colored highlight box over text. Click to place, then drag the corners to resize it to fit your content.
Whiteout
Cover sensitive information with a white box. Perfect for redacting personal details before sharing a document.
Image
Insert an image (PNG or JPG) into your PDF. After selecting the image, it will appear on the page and you can drag it to reposition or resize it.
💡 Pro Tip: How to Add and Edit Text
- Select the Text tool from the toolbar.
- Type your text in the Text field in the options panel that appears.
- Adjust the font size and color as needed.
- Click anywhere on the PDF to place your text at that position.
- To edit the text after placing it, switch to the Select tool and double-click the text — a popup will appear where you can change the content.
- To move the text, use the Select tool and drag it to a new position.
Select, Move, and Delete Annotations
Use the Select tool (👆) to interact with annotations you've already added. Click any annotation to select it — you'll see an orange dashed border. Then drag it to move it, or drag the corner handles to resize it. To delete a selected annotation, click the 🗑️ Delete button in the toolbar.
Save and Download Your Edited PDF
When you're happy with your edits, click the Save PDF button in the top bar. PDFCamel will process your file and a Download button will appear. Click it to save your edited PDF to your device.

Frequently Asked Questions
Is PDFCamel's PDF editor really free?
Yes, completely free. No sign-up, no credit card, no hidden fees. All editing tools are available at no cost.
Is my PDF file secure?
Your file is processed locally in your browser using pdf-lib. Your document is never uploaded to or stored on our servers.
Can I edit text that already exists in the PDF?
The current editor lets you add new text on top of existing content. To edit original PDF text, you would need a full PDF editing application. However, you can use the Whiteout tool to cover existing text and then add new text on top.
Why does my text position look slightly different after downloading?
There may be very minor positioning differences due to font rendering differences between the browser and PDF engines. For best results, zoom in before placing text and verify the position in the preview.
Can I edit multiple pages?
Yes! Use the ◀ ▶ navigation buttons in the top bar to switch between pages and add annotations to any page before saving.
