Frequently Asked Questions
Will image quality decrease after converting JPG to PDF?
No. This tool embeds JPG images into the PDF as-is without re-compression or scaling. Image quality is fully preserved. PDF serves only as a container format.
How many images can I convert at once?
You can batch upload multiple JPG images, each becoming one page in the PDF. We recommend no more than 100 images at a time, depending on your device's memory. Images are arranged in upload order.
Are my images uploaded to a server?
No. This tool runs entirely in your browser using the jsPDF library. Image data never leaves your device and is not uploaded to any server, ensuring your privacy.
Can I set the PDF page size and orientation?
Yes. Choose from A4, A3, Letter, Legal, or auto-fit to image dimensions. Orientation options include portrait, landscape, or auto-detect. You can also set image fit mode and page margins.
What is the file size of the converted PDF?
The PDF file size is approximately equal to the sum of all original image sizes plus minimal PDF structure overhead (usually less than 1%). Since images are embedded as-is, the file size does not increase significantly.
