Compress PDF to 600KB
600KB is the roomy side of sub-megabyte: twenty-plus scanned pages, image-heavy reports, or a 1MB requirement met with margin to spare. 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.

Generosity you can spend
At 600KB, the per-page budget stops forcing choices — long scans stay crisp, photos stay detailed, and the document simply gets smaller without visible cost. Most compression at this tier is removing scanner bloat, not quality.
