How to compress jpg images online
Reduce a JPG file size quickly without uploading it to a server. Choose a target size and File Chisel will find a practical quality setting automatically.
Why use File Chisel?
File Chisel is designed around the outcome you need rather than a long list of technical settings. Choose a supported image, set the requirement, process it, and download a separate finished copy.
Is my image uploaded?
For the image tool on this page, processing happens in your browser using browser image APIs. The source file is not sent to a File Chisel server by this application.
What happens to the original?
Your original stays on your device. File Chisel creates a separate output file for download.
Tips for a better result
- Use JPG for photographs when transparency is not required.
- Use the exact target size when a website or form provides a KB or MB limit.
- For very large images, reducing dimensions can cut file size more than quality changes alone.
Frequently asked questions
Does File Chisel upload my JPG?
No. This image tool processes supported files in your browser.
Will compression change image dimensions?
File Chisel first reduces encoding quality. If needed to reach a very small target, it can also reduce dimensions.
What target size should I use?
Use the exact KB or MB limit provided by the website, form, marketplace, or application you are uploading to.
