How to use Compress Image to KB
- 1
Choose up to 20 JPG, PNG, or WebP images.
- 2
Apply a shared KB target to checked images or set each image separately.
- 3
Compress locally and download individual results or the complete batch as a ZIP.
Exact size cannot be guaranteed because encoders produce discrete results. The tool lowers quality and, when necessary, dimensions to meet the maximum.
When to use this tool
Use this tool when an upload form sets a maximum image size. Add one image or a batch, apply a shared target where useful, and keep individual targets for files with different requirements. It searches output settings locally and aims for the largest result that does not exceed each target.
PRACTICAL EXAMPLE
Meeting a 50 KB limit
- Start with
- A portrait photo and a maximum size of 50 KB.
- What to expect
- The tool tests progressively smaller outputs and keeps the best result it can produce at or below 50 KB.
Get a better result
- Choose JPG for photographs and PNG when sharp flat graphics or transparency matter.
- Very small targets may require fewer pixels as well as stronger compression. Download all becomes available after every image has a result.
Common questions
Does this upload my file?
No. Processing runs in your browser and ToolRino does not receive the file.
Does it replace my original?
No. The tool creates a new download. Keep the original until you have checked the result.
