Compress an image to an exact size — including a range

Upload forms rarely say “make it smaller”. They say “photo must be 20–50 KB”, or “under 100 KB”, and reject everything else. Indian exam and recruitment portals (SSC, IBPS, UPSC and state boards) are strict about both ends of the window; visa, passport and job portals worldwide pull the same trick. This tool targets a size, not a quality slider: tell it the maximum — or a minimum and maximum — and it searches quality settings (and, only if truly necessary, dimensions) until the file lands where the form wants it.

How to use it

  1. Add your image. Note its current size and dimensions.
  2. Tap a preset (20 / 50 / 100 / 200 KB) or type your own maximum — or switch to Range mode and enter both ends of the window.
  3. Press Compress. The tool binary-searches the quality for the largest file that still fits, stepping the dimensions down only if quality alone cannot reach the target.
  4. Download and check the reported size before you upload it to the form.

Honest limits

A file can only hold so much picture: a 6000 × 4000 photo squeezed under 20 KB will look soft no matter what, and a tiny image cannot honestly be stretched up to a large minimum without adding empty bulk — when a range is genuinely unreachable at sane settings, the tool says so and gives you the closest result instead of padding the file with junk bytes.

Frequently asked questions

Why do forms reject a photo that is too SMALL?
Portals with a size range use it as a rough quality and format check: a 3 KB “photo” is assumed to be a thumbnail, a scan of a scan, or the wrong file entirely. Range mode exists precisely for those portals — it finds settings whose output lands inside the window instead of hugging the floor.
What is the difference between this and the regular Image Compressor?
The regular compressor targets a quality or a percentage. This one targets bytes: it searches quality (and dimensions, as a last resort) until the output fits your stated maximum or range, then reports the exact size achieved.
Will the dimensions change?
Only when they must. Quality is searched first across its full range; dimensions step down (keeping aspect) only if even the lowest usable quality is still too big. The result panel always shows the final dimensions.
Is my photo uploaded?
No — compression happens on a canvas in your browser. The file you download is generated on your own device.
