I always see people asking for something original. What does the original text mean?

The original image refers to a picture without watermark, which has not been compressed and modified.

When uploading pictures, many pictures will be compressed to low resolution due to the server traffic limitation of the APP, which is easy to be distorted and has low definition after opening the big picture. There are also some pictures that will be watermarked after being uploaded to the APP. For example, after the pictures of Weibo are reproduced, the original PO owner's name will be marked in the lower right corner.

Some pictures will upload filters and text, which is not suitable for others to use again. After you want the original picture, you can browse and edit it as needed, which is more convenient.

Common picture formats

1 and JPEG are the most common image formats, which are widely used, especially in the network and CD-ROM books. Various browsers support JPEG as an image format, because the file size of JPEG format is small and the download speed is fast.

2.BMP is an image file format that has nothing to do with hardware devices and is widely used. It uses bitmap storage format and does not use any other compression except image depth, so BMP files take up a lot of space.

3. The characteristic of GIF format is that it can store multi-color images in a GIF file. If a plurality of image data stored in a file are read out one by one and displayed on the screen, the simplest animation can be formed.
