When to Use an Online PDF Editor
📝
Filling Non-Interactive Forms
Someone sent you a scanned application or a PDF without fillable fields. Just drop text boxes over the lines to type your responses.
🏫
Grading & Reviewing
Teachers or managers can upload assignments and use the text/drawing tools to leave red-pen feedback or grade directly on the document.
✒️
Adding Signatures & Dates
Place your digital signature on a contract and quickly type the current date next to it before submitting the final agreement.
✏️
Making Corrections
Notice a typo on a final brochure but don't have the source file? Place a white rectangle over the error, and type the correct text over it.
Common Mistakes & Pro Tips
Avoid these errors when marking up a PDF.
✗
Trying to backspace original text
This tool lets you annotate *over* the PDF. It does not convert the PDF into Word to let you rewrite paragraphs. If you need to rewrite core sections, use our PDF to Word tool instead.
⚠️
Using black boxes for redactions
Drawing a black rectangle over sensitive text does not actually erase the data underneath—someone can just scrape it. To permanently censor data, use a true Redact PDF tool.
✓
Pro tip: Flatten your annotations
Once you click download, we automatically "flatten" your text boxes into the PDF. This ensures that the person you email the file to cannot accidentally move the text you placed.
Frequently Asked Questions
How do I edit a PDF?
Upload your PDF file, then use our tools to add text annotations, highlight sections, or draw directly anywhere on the document. Click save to download your edited PDF.
Can I add text to any position?
Yes! Click anywhere on the PDF page to drop a text box. You can freely drag, drop, resize, and change the font color of your text annotations.
Can I edit the existing text in the PDF?
No. Our tool acts as an overlay editor/annotator. It allows you to add text over forms, hide existing text with white boxes, and add signatures, but it does not let you backspace existing core text.
Will the original PDF be modified permanently?
Your annotations are added as a new, flattened graphical layer upon export. The original file you uploaded on your hard drive remains untouched.
Is this a good tool for filling out PDF forms?
Absolutely. If you receive a flat PDF that isn't an interactive form, you can simply use the text tool to type your answers directly over the blank lines.
Does this work on mobile and tablet touchscreens?
Yes, the editor works seamlessly on iPads and Android tablets so you can use your stylus or finger to sign documents or write notes.
Is my PDF secure?
Yes! All rendering and editing processes happen exclusively in your browser window. Your private PDFs are never uploaded to cloud servers.
