Compress to a Target File Size
Automatically find the highest image quality that still fits under a KB size limit you specify.
- 100% free
- No upload — runs in your browser
- No sign-up needed
Some upload forms enforce a strict maximum file size — a job application portal capped at 200 KB, a visa application system, a government form. Instead of guessing quality percentages by trial and error, this tool runs a quick automatic search across quality levels and returns the best-looking result that still fits under your target, in one click.
How to Compress to a Target File Size
- Add your image(s).
- Enter the target size in KB.
- Click "Compress to target size" and download the result.
Frequently asked questions
What happens if my target size is smaller than the tool can achieve?
The tool searches down to a minimum viable quality and returns its closest result; extremely small targets on large or highly detailed images may not be fully reachable without visible quality loss.
Does this work for PNG files too?
Yes — like the standard compressor, PNGs are automatically handled via JPG re-encoding, since JPG's lossy compression is what allows hitting a specific target size.
Is the target size exact, or approximate?
It's a "fits under" guarantee, not an exact match — the tool searches for the highest quality that keeps the file at or below your target, so the final size is usually close to, but not precisely, that number.
