Browser-based
Set any target KB value and upload your image. The tool adjusts JPEG quality to get as close as possible to your exact size limit.
How to use this tool
Set your target KB, upload a JPG or PNG, and compress. Download the output and confirm the final size.
Worked example
Example: targeting exactly 150 KB for an online form may land at 148–152 KB after quality tuning.
How it works
Enter an exact target file size in kilobytes, upload an image, and compress locally with JPEG quality binary search. The tool scales the image down when quality alone cannot hit your target.
Limitations
Processing runs in your browser when possible. Verify outputs before using them in production or official submissions.
Privacy and file handling
