FAQ

Can every PDF reach exactly 1 MB?
No. A 50-page photo scan may not fit in 1 MB while staying useful. Target size aims for the limit; we stop when further compression would be unreasonable.
Is this different from normal Compress PDF?
Same tool — this page is optimized for the “compress to 1 MB” search intent and points you at the target-size option.
