+
+import (
+	"bytes"
+	"fmt"
+
+	"github.com/ledongthuc/pdf"
+)
+
+func main() {
+	content, err := readPdf("test.pdf") // Read local pdf file
+	if err != nil {
+		panic(err)
+	}
+	fmt.Println(content)
+	return
+}
+
+func readPdf(path string) (string, error) {
+	r, err := pdf.Open(path)
+	if err != nil {
+		return "", err
+	}
+
+	var buf bytes.Buffer
+	buf.ReadFrom(r.GetPlainText())
+	return buf.String(), nil
+}
+```
+
+## Read all text with styles from PDF
+
+```golang
+func readPdf2(path string) (string, error) {
+	r, err := pdf.Open(path)
+	if err != nil {
+		return "", err
+	}
+	totalPage := r.NumPage()
+
+	for pageIndex := 1; pageIndex <= totalPage; pageIndex++ {
+		p := r.Page(pageIndex)
+		if p.V.IsNull() {
+			continue
+		}
+		var lastTextStyle pdf.Text
+		texts := p.Content().Text
+		for _, text := range texts {
+			if isSameSentence(text, lastTextStyle) {
+				lastTextStyle.S = lastTextStyle.S + text.S
+			} else {
+				fmt.Printf("Font: %s, Font-size: %f, x: %f, y: %f, content: %s \n", lastTextStyle.Font, lastTextStyle.FontSize, lastTextStyle.X, lastTextStyle.Y, lastTextStyle.S)
+				lastTextStyle = text
