Compress to Target Size
Upload one image, choose a target size or percentage reduction, and run a browser-side best-effort compression pass.
Accepted: PNG, JPG, JPEG, WEBP. Choose either a target size or a percentage reduction. Best effort in the browser: large images may be downscaled to approach the selected goal, and some files can still finish above it. Large images may fail on phones or low-memory devices.
How to use
Compress Image to Target Size reduces an image file to a specific kilobyte or megabyte target — 100 KB, 200 KB, 500 KB, or a custom value you set. Processing runs entirely in your browser.
- Upload your image
Select a JPG, PNG, or WEBP image. The tool shows the current file size so you know the starting point.
- Set the target size
Choose a preset (100 KB, 200 KB, 500 KB, 1 MB) or enter a custom value. You can also choose a percentage reduction instead.
- Compress
Click Compress. The browser iterates the JPEG quality or PNG compression to get as close to your target as possible.
- Download the result
Download the compressed image. The tool shows the final file size and the quality level used so you can judge whether the output meets your needs.
Note: Results are best-effort. Images that are already heavily compressed may not reach the target without visible quality loss.
