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.

Max 10 MB. JPEG, PNG, GIF, WEBP, TIFF.
Iteratively reduces quality and (if needed) dimensions until the target is reached.

How to use the reduce image size tool

  1. Upload your image.
  2. Choose the output format (JPEG, WEBP, or PNG).
  3. Enter the target size in kilobytes (e.g. 100).
  4. 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.
