Government forms, university portals, and job sites demand tiny uploads. Use our Maximum preset to compress PDF under 100KB, under 200KB, under 300KB, under 500KB, or under 1MB — then verify the output size before you submit.

Check the portal requirement first — 100KB, 200KB, 300KB, 500KB, or 1MB.
Maximum forces the smallest Ghostscript output. Re-run if you still need to compress PDF under a lower KB threshold.
We return original vs output bytes so you know you hit compress PDF under 1MB (or your target) before uploading.
Resume PDFs must often compress PDF under 200KB or 300KB — Maximum preset is built for this.
Strict caps like compress PDF under 100KB are common; iterate with Maximum until you qualify.
When a form says compress PDF under 500KB, one pass usually suffices for multi-page scans.
Embassy uploads frequently require compress PDF under 1MB — verify headers after download.
Generic compressors do not target 100KB or 200KB goals. Our Maximum preset is tuned for aggressive shrink.
Long scanned PDFs need VPS Ghostscript — not a browser-only script that times out.
Convertify4u shows byte counts so you know you met compress PDF under 300KB before leaving the page.
Ghostscript /screen-style settings on VPS for the smallest practical output.
Compare original and compressed bytes in the UI toast.
