Reduce Image Size
Reduce image file size to any target in KB. Enter your desired file size and pick an output format — the tool iteratively lowers quality and, if needed, dimensions until your image fits. Perfect for upload forms with strict size limits.
How to use the reduce image size tool
- Upload your image.
- Choose the output format (JPEG, WEBP, or PNG).
- Enter the target size in kilobytes (e.g. 100).
- Click “Process Image” — the result page shows the before/after size.
Frequently Asked Questions
How does the tool reach the target size?
It reduces JPEG/WEBP quality in steps and, if quality reaches its minimum, shrinks dimensions by 10% per pass until your file is under the target.
What if it can’t reach my target?
If the target is unreasonably small you’ll see a friendly error. Try a larger target, or use WEBP output — it compresses better than JPEG.
Which format should I choose?
WEBP gives the smallest files for photos, JPEG is universally supported, PNG is best for logos with flat colours (but compresses less aggressively).
Is there a maximum target size?
No upper limit. The tool stops as soon as your file is under the target — no unnecessary re-encoding.
