About Compress JPG to 100KB – JPEG Size Optimizer

Dedicated JPEG optimizer engineered specifically to compress JPG and JPEG photos down to 100 KB or less.

The image is decoded and processed locally in your browser; it is not uploaded to Navorika.

How to use this tool

  1. 1Upload a JPG or JPEG photo.
  2. 2Our engine computes the highest JPEG quality level that fits strictly within 100 KB.
  3. 3Review the selected JPEG quality rating, pixel dimensions, and byte size.
  4. 4Download your optimized JPEG.

Understanding the result

JPEG uses discrete cosine transform (DCT) lossy compression, which is highly responsive to quality fine-tuning.

The algorithm binary-searches between 12% and 94% quality to find the exact threshold under 100 KB.

Important limitations

  • JPEG does not support alpha transparency; transparent areas in converted images are filled white.
  • Progressive JPEG encoding depends on browser canvas implementation.

Frequently asked questions

What happens if a photo cannot reach 100 KB at minimum quality?

If quality reduction alone cannot achieve 100 KB, the optimizer proportionally scales dimensions down until the file fits.

Is EXIF metadata preserved?

Canvas re-encoding strips EXIF tags, which also helps reduce unnecessary file size.

Is there an upload limit?

The browser safety ceiling is 25 MB per image.
