The difference between PDF and JPEG!!!

The difference between PDF and JPEG

JPEG and PDF are the two most popular file data formats that are primarily used to save and share service content. In terms of displaying digital images and text teaching content management, each of them has advantages and disadvantages, pdf editor freeand here we can gain a deeper understanding of the nature and functions of JPEG and PDF in order to use them in a correct scene.

What is JPEG?

JPEG (or JPG) stands for Joint Photographic Expert Group. It is one of the most widely used image file formats in the world. JPEG compresses colorful photos to a small size, making it the best way to store and share digital images, and ideal for social, email, and Internet photo transfer.

What is PDF?

PDF is an abbreviation for Portable Document Format, meaning "portable Document Format". It is a file format developed by Adobe Systems for file exchange, independent of applications, operating systems, and hardware. PDF is platform-independent, that is, PDF files are common across Windows, Linux, and Apple's Mac OS operating systems.

This feature makes it an ideal file format for electronic document distribution and digital information dissemination on the network. More and more e-books, product descriptions, company circulars, web materials, e-mails are starting to use PDF files. At the same time, PDF is ideal for printing, as it maintains the integrity of all page components and ensures the image quality after magnification.

What is the difference between JPEG and PDF?

Both JPEG and PDF can be used to store and share image and text data, but there is no difference between the two formats for some problems.

Compression aspect

JPEG uses lossy data compression, which can permanently damage a file when it is compressed. By removing redundant images and color data, very high compression rates can be obtained while displaying very rich and vivid images. In other words, better image quality with minimal disk space. The file size is relatively small, so it is easy to store and share on the network.

The compression method used in PDF does not compromise the original quality of the file, and its file size will be larger than JPEG. PDF encapsulates device-and resolution-independent words, fonts, formats, colors, graphics, and images in a single file. Suitable for storing rich files. But it's hard to integrate into web pages.

editable

The main advantage of PDF is that it preserves the layout of the content, so that different components are independent, all parts can be edited, different component content can also be edited separately (requires a specific editor, such as Acrobat Pro), and the file can contain electronic information such as hypertext links, audio and moving images.

JPEG files have been compressed and synthesized in the image at the time of generation, all the content is in one layer, is a whole, does not support the editing of the original component.

This means that PDF is a format that allows the student user to copy part of the text or image information content in certain circumstances. But PDF can not embed the entire design file in other related documents, if we want to embed images in different documents in China, we can only use JPEG format.

JPEG and PDF files: Common problems

Which picture quality is higher, JPEG or PDF?

PDF is usually of higher quality than JPEG. This is because JPEG uses lossy data compression to compress images, resulting in an irreversible loss of quality. And the visual quality of PDF is high, and it is also the preferred format for printing files.

Is PDF larger than JPEG?

PDF is usually larger than JPEG in this case because PDF can display content-rich media (i.e. video, audio, animation, and other information interaction design experiences), whereas JPEG usually contains only a single target image. Another major reason JPEG is smaller than PDF is that its lossy data format offers higher compression rates than PDF in terms of quality management tradeoffs.

Can you convert PDF to JPEG or JPEG to PDF?

There are many ways to convert between PDF and JPEG formats. To convert PDF to JPEG, you can use the plotter's PDF to picture feature (http: u002F u002 fwww.zhituji.cn).

How to digitally sign JPEG?

JPEG is not suitable for digital signatures. You can add graphics and text to a JPEG by clicking the Drawing tool on the Edit menu and saving the file again. However, this method is not standardized and many recipients of digital signatures may not accept it. A more legitimate way to sign a JPEG file is to print the file, sign it physically, and then scan the document for digitization.

In relatively simple terms, PDF is very suitable for students to study digital signature, can directly use the digital signature function in the PDF editor to sign, there are also many third-party payment tools we can analyze the digital signature, and the signature is legal.
