A 200 KB cap is common for website uploads and application forms. Lumagely’s Target file size mode automatically dials in the highest JPEG, WebP or AVIF quality that stays under your limit — no guesswork, no upload.

How to compress an image to 200 KB

  1. 1Drop your image in — the target is preset to 200 KB.
  2. 2Change the limit or output format if you like.
  3. 3Download the result, or the whole batch as a ZIP.

Good to know

  • Target mode works with JPEG, WebP and AVIF.
  • Combine with resize for very large photos that won’t fit by quality alone.
  • Any KB target works — 50, 100, 500 and so on.
