Every day, you use or see a JPEG image file.
Its widespread use on 77.9% of all websites makes JPEG images prevalent.
Not only that,
- 79.2% of the top 1 million websites use JPEG.
- 77.5% of the top 10000 websites use JPEG.
- 74.2% of the top 1000 websites use JPEG.
One of the reasons for JPEG’s broad acceptance is its high compression rate. So, you can compress JPEG images to any size you want.
However, you want to preserve your image without affecting it.
In this article, we’ll show you how to compress JPEG images without losing quality.
What Is a JPEG Image File?
In the ’80s and ’90s, the Joint Photographic Experts Group (JPEG) standardized a file format for digital photographs. Since then, it has surpassed all other image formats in popularity.
JPEG is the best choice for website use and the most popular image format, with 77.8% of sites using JPEG. It’s also beneficial for email attachments, large photos, and archiving.
It uses lossy compression and supports 24-bit colors, allowing image compression ratios ranging from 10:1 to 20:1. But, it degrades the original image quality.
The quality loss suffered by using JPEG is not a dealbreaker in most cases, so the format remains popular. But, it may be preferable for small-size images such as logos.
JPEG images share these filename extensions: .jpg, .jpeg, .jpe, .jif, .jfif and .jfi.
Advantages of using JPEG images:
- JPEG files are compatible with most browsers, software, and apps.
- JPEG files are highly compressible. You can adjust JPEG image compression to fit any size.
- JPEG images are small and easy to upload to websites.
- With 24-bit color and 16 million colors, high-resolution JPEG images are vibrant.
JPEG vs. JPG
There’s no difference between JPG and JPEG. They are precisely the same thing but have different names.
The JPG format was developed because the early version of Windows (MS-DOS 8.3 and FAT-16) only supported three-letter file extensions. They just altered the characters to fit the system.
Since they are the same type, you can use any format have the exact small file sizes and vibrant colors.
Why Would You Compress JPEG Images?
Like yours, every website uses JPEG images daily. And file size dramatically affects how well they work. Large file sizes can make it take longer for a page to load, which is vital for a good user experience.
Over 45% of online shoppers are less likely to buy from eCommerce stores that take longer than expected to load, according to Unbouce research.
Google’s ranking algorithm also gives a lot of weight to how quickly a page loads. So, your website must load quickly to rank on the first page of search results.
Aside from user experience and SEO considerations, large file sizes impact your website’s cloud storage usage. So, you must compress and reduce the file size of JPEG images to improve user experience and SEO.
