How to Compress JPG with Different Online and Offline Tools

Compressing an image means modifying it in some way to make it smaller in terms of file size. Any image compressor you use to compress JPG files will apply downsampling algorithms that will impact the resolution of y our image. That's why it's a good idea to know what to use and how each of these image compression tools works.

The good thing about image compressors is that there are a lot of free and paid tools available for the job. However, not all of them will give you the same kind of output quality. For instance, a free JPG compress utility might seem attractive, but what's the use if you can't even view the image clearly on a browser after compression? On the other hand, what if you pay for software to compress JPG and you don't find it good enough for your needs?

To help you overcome such challenges, we tested a whole lot of image compressor tools - online and offline variations, as well as free and paid options. This article outlines our findings.

Part 1: People Always Ask (FAQs)

Q1: How do I compress multiple images without losing quality?

This can be done manually one at a time but is obviously time-consuming. The better alternative is to use a tool with a batch process feature that can handle file conversions in an automated queue. All you need to do is apply the global settings such as compression level, output quality, resolution requirements, dimension requirements, etc. and let the tool handle the difficult part. And DO remember to use minimal compression levels to ensure the best quality.

Q2: Is using an image compressor safe?

Yes, most image compression utilities offer user-friendly interfaces so you don't need to do any complex actions. Besides, your original file is always safe since you're only uploading a copy of it to the web (in the case of an online image compressor) or creating an optimized copy (in the case of desktop image compressor tools.) If you want to play it really safe, create a copy of the original and then process the copy. This will ensure that your original file is untouched.
