This can be problematic if the original image needs to be restored because the compression method is no longer suitable for the intended use. Irreversibility - After an image is compressed using a lossy method, it is not possible to recover the original image.Depending on the degree of compression and the characteristics of the image, this loss of quality can be noticeable and may reduce the usefulness of the image. Loss of quality - The main disadvantage of lossy compression is that it can result in a loss of image quality.Reasonable quality - Lossy compression can achieve good image quality with a reasonable degree of compression, making it suitable for most applications where highest-quality images are not essential.Faster transmission - Smaller file sizes also means faster transmission over networks or the internet, which can improve the user experience.Smaller file size - Lossy compression can result in significantly smaller file sizes, which can be beneficial when storing large numbers of files.It removes information that is less important or perceptually less significant, such as high detail or color information that is outside the range of human vision. Lossy image compression is a method of reducing an image’s file size by selectively discarding some of the image data. Lossy compression suits a variety of situations where file size is a primary concern, and the quality of the document can tolerate some loss of detail or information. To prioritize file size reduction, PaperCut MF uses lossy compression.

The conversions across different file types increase the final PDF file size. For example, it converts pages to a PNG to optically recognize the text to create the searchable OCR text layer, or to check how blank a page is to decide if it can be removed (if blank page removal is enabled).Īfter conversion to PNG, the pages are reassembled in a PDF. When PaperCut MF processes a document with any of the features above, it converts the PDF pages into PNG image files to analyze them. OCR (optical character recognition) to create searchable PDFs.Many organizations impose file size restrictions on email attachments, so the scanned PDF files need to be an email-friendly file size.Įnabling any of these document processing features causes the PDF file sizes to increase: This is useful when you need to send PDFs by email, and also reduces the amount of file storage required. Use scan compression to reduce a scan’s PDF file size. PRODUCTS FEATURED Scan PDF compression When is scan compression useful?
