Why 1 MB?
Email services, visa portals and HR systems often set a 1 MB limit per attachment. Larger scans and photo-heavy reports usually need compressing to fit.

- If the size you ask for cannot be reached, you get the closest result and the reason.

Questions
Is 1 MB the same as 1,000 KB or 1,024 KB?
It depends on the system. We aim under 1,000,000 bytes, the stricter reading, so the file is accepted either way.
How do you get a PDF under 1 MB?
We make photos and scanned pages smaller step by step, checking the size each time, and keep the best quality that fits. Text and fonts are not changed.
What if it cannot reach 1 MB?
You get the smallest file we could make and the reason, for example that the text and fonts alone take more space. You can allow pages to be turned into images to go further, at the cost of selectable text.
Is my file uploaded?
No. The compression runs in your browser on this device, and keeps working offline once the page has loaded.
