Compress PDF to 800KB
800KB spends almost the whole megabyte on quality while keeping a real buffer under 1MB gates — the maximalist\'s sub-MB target. We compress toward your target at the best quality that fits, never make the file larger than the original, and always show the real final size — very image-heavy files may land slightly above tight targets.

The most quality a 1MB cap allows, safely
Against a 1MB requirement, targeting 800KB preserves nearly everything the full budget would — while the 200KB buffer absorbs strict measurement, metadata overhead and re-encoding quirks that bounce 990KB files off 1MB gates.
For documents that deserve the budget
Portfolio pieces, photo-documented reports, long official bundles — when the content justifies spending big, 800KB is how you spend it without gambling the upload.
