The difference between PDF and JPEG

JPEG and PDF are the two most popular file data formats, circuit printing service which are mainly used to save and share service content. In terms of displaying digital images and text teaching content management, they have their own advantages and disadvantages. Here we can have a deeper understanding of the essence and functions of JPEG and PDF, so as to use them in the correct scene.

What is JPEG?

JPEG (or JPG) represents the joint photographic expert group. PCB fabrication company It is one of the most widely used image file formats in the world. JPEG compresses color photos into small sizes, making them the best way to store and share digital images, and ideal for social, e-mail, and internet photo transfers.

What is PDF?

PDF is the abbreviation of portable document format, china PCB which means "portable document format". It is a file format developed by Adobe Systems for file exchange, which is independent of applications, operating systems and hardware. PDF is platform-independent, that is, PDF files are common among 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 announcements, online materials and emails are using PDF files. At the same time, PDF is an ideal choice for printing, because it can maintain the integrity of all page components and ensure the quality of the enlarged image.

What's the difference between JPEG and PDF?

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

Compression aspect

JPEG uses lossy data compression, which will permanently damage files. By deleting redundant images and color data, a very high compression rate can be obtained, and very rich and vivid images can be displayed at the same time. In other words, better image quality can be obtained with the least 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 affect the original quality of the file, which will be larger than JPEG. PDF encapsulates device-and resolution-independent words, fonts, formatting, colors, graphics, and images in one file. For storing rich files. But it's hard to integrate into a web page.

editable

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

JPEG files are generated when the image is compressed and composited, all content is on a level, is a whole, does not support editing of the original components.

This means that PDF is a format that allows student users to copy some text or image information in some cases. However, PDF can't embed the whole design file into other related documents. If you want to embed images in different documents in China, you can only use JPEG format.

JPEG and PDF files: Common problems

Which image is better, JPEG or PDF?

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

Is PDF larger than JPEG?

In this case, PDF is usually larger than JPEG because PDF can display rich media (such as video, audio, animation, and other information interaction design experiences) , jPEG usually contains only one target image. Another major reason that JPEG is smaller than PDF is that its lossy data format provides higher compression rates for quality management than PDF.

Can you convert PDF into JPEG or JPEG into 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 convert to a picture feature (< URL > U002 FWWW.ZHITUJI.CN ) .

How to digitally sign JPEG?

JPEG is not suitable for digital signature. You can add graphics and text to 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 legal way to sign a JPEG file is to print the file, physically sign it, and then scan the document to digitize it.

Simply put, pdfs are great for students to learn about digital signatures. You can sign directly using the digital signature feature in the PDF editor, and there are many third-party payment tools that can be used to analyze digital signatures, and the signature is legal.
