Helpful answers

Why is my PDF still over the KB target?

Image-heavy scans and embedded fonts keep size high. Try a lower target, remove unused pages, or compress images before merging. Password-locked files may need unlocking first.

Is compress-to-KB different from regular PDF compress?

Target-KB mode aims for a hard ceiling (for portals and email gates). General compress aims for smaller files without a precise byte budget—use target mode when the limit is strict.

Is Compress PDF to 100KB / 200KB / 500KB free to use?

Yes. Utilnivo tools are free to use and do not require an account.
