Hi Chetan,

Replace createPDF() method's if condition with the below code to merge all the pages of multiple PDF files.

    if (this.docData.length > 1) {
        for (let i = 1; i < this.docData.length; i++) {
            tempBytes = Uint8Array.from(atob(this.docData[i]), (c) => c.charCodeAt(0));
            console.log('tempBtes>> ', tempBytes);

            const usConstitutionPdf = await PDFLib.PDFDocument.load(tempBytes);
            console.log('After123 ', usConstitutionPdf.getPages().length)
            for(let j =0; j<usConstitutionPdf.getPages().length; j++){
                page = pdfDoc.addPage();
                const preamble = await pdfDoc.embedPage(usConstitutionPdf.getPages()[j]);
                console.log(' Inside page is ', page)

                const preambleDims = preamble.scale(0.95);

                page.drawPage(preamble, {
                    ...preambleDims,
                    x: page.getWidth() - americanFlagDims.width,
                    y: page.getHeight() - americanFlagDims.height - 10,
                });
            }

        }

    }
