Image Size Compressor (KB/MB)
Compress images to a target file size
The essentials
The Image Size Compressor hits an exact file-size target — 50 KB for a government form, 200 KB for an application portal — by automatically tuning quality and dimensions until your image fits.
How to use it
- Upload your image.
- Type the target size and choose KB or MB.
- Run the compression — the tool searches for the best quality that fits.
- Download the image, guaranteed at or under your limit.
Pro tips
- Very small targets (under 30 KB) may need reduced dimensions — that is normal.
- JPG/WebP reach small targets more easily than PNG.
- If the result looks soft, raise the target slightly for a big quality jump.
Behind the result
The tool runs an iterative search: it re-encodes the image at different quality levels — and gently reduces dimensions only if quality alone cannot reach the goal — measuring real output bytes each round until the file fits your limit.
A worked example
A government portal rejects photos over 50 KB.
- Input
- A 2.4 MB JPG passport-style photo.
- Output
- A 49 KB JPG that the portal accepts on the first try.
