Frequently Asked Questions
Yes, our JPG to PDF converter is completely free to use. There are no hidden fees, no watermarks, and no registration requirements. You can convert as many images as you want without any limitations.
Absolutely. All file processing happens directly in your browser using JavaScript. Your images are never uploaded to any server, which means they never leave your computer. This ensures complete privacy and security for your documents.
There are no specific file size limits imposed by our tool. However, very large images may take longer to process depending on your device’s capabilities. For optimal performance, we recommend converting images under 10MB each.
Currently, our tool specifically supports JPG and JPEG formats. While other image formats might work, we can’t guarantee optimal results. For best performance, we recommend converting other image types to JPG before using our tool.
For the highest quality output, set the quality slider to 100% and disable the compression option. Keep in mind that this will result in larger PDF file sizes. For a good balance between quality and file size, we recommend using 80-90% quality.
