Is PDF lossy

No, PDF (Portable Document Format) is not inherently lossy. It is a versatile file format that can contain text, images, and vector graphics, and it supports both lossless and lossy compression methods depending on how the content is encoded. For example, images within a PDF can be saved in a lossy format (like JPEG) or a lossless format (like PNG). The overall quality depends on the settings chosen during the PDF creation process.
