  • JPG What is JPG File Format

    A JPEG is a type of image format that is saved using the method of lossy compression. The output image, as result of compression, is a trade-off between storage size and image quality. Users can adjust the compression level to achieve the desired quality level while at the same time reduce the storage size. Image quality is negligibly affected if 10:1 compression is applied to the image. The higher the compression value, the higher the degradation in image quality.

    Searchable PDF What is Searchable PDF File Format

    Searchable PDF files retain the original scanned image for viewing, as well as OCR text in a hidden layer that can be used for full-text searches within a document or highlighting text for copy and paste operations. Full OCR conversion to PDF, not including the original image, will never retain 100% of the original formatting, especially if the document has many images or a complex layout.
