To compress JPG means to make it even smaller than the original file, which is already in a lossy compression format. For that reason, you need to pick your ‘shrink JPEG' tool carefully, regardless of whether it's an online service, a desktop application, or a mobile app. In this article, we've categorized the top tools to compress PDF online and offline. The web options don't need any installation, but some users may prefer the enhanced privacy of a desktop or mobile solution.
The tool you finally choose should depend on your need more than anything else. For instance, if you want to compress a file for web use, a high compression setting is good because that's where the maximum file size reduction happens. On the other hand, an outdoor print job such as a banner or billboard might require low compression in order to maintain image quality and scalability.
Collectively, this diverse range of tools to compress JPEG files has everything you need.
Part 1: Frequently Asked Questions
Q1: How do I compress JPEG to 50KB?
The ability to compress JPEG to 200KB, 100KB, or 50KB depends entirely on the size of the original file, the compression level you choose, and the actual compression percentage the tool can achieve. A 300KB file, for instance, can easily be compressed to 50KB (one-sixth), but a 500KB file will need a powerful compression engine to get it down by 90%. It's definitely possible with the right tool
Q2: Online vs. Offline JPEG Compression - the better option?
As we mentioned, an offline or desktop/mobile utility gives you greater privacy as well as the ability to process large files or compress in bulk. Some online tools also offer this but the file sizes are usually restricted along with the number of files you can process in a single queue. If it's hard to choose, think of your top priority (speed vs. accessibility, etc.) to pick the right option.

With a plethora of conversion, compression, and other tools to handle PDFs, it is a very capable online utility.
