What you get
Room to breathe
At 1MB you're removing genuine excess rather than trading away readability, which is why this is the target to pick when nothing forces a tighter one.
Suits long documents
A thirty-page report can sit inside 1MB and still look like a report.
Sensible default for sharing
Small enough for any inbox, large enough that nobody asks you to resend a legible copy.

Common questions
Will anyone notice the compression at 1MB?
On a typical text or mixed document, no. This is the target where the result is hard to tell from the original at normal viewing size. Fine detail in photographs is where it would show first.
My 40-page report is 25MB. Where is that coming from?
Almost certainly images placed at full camera resolution. A photograph displayed at postcard size on the page can still be carrying twelve megapixels of data that nothing will ever use.
Should I compress to 1MB or leave the file alone?
If it's already under a couple of megabytes and nobody has complained, leave it. Compression is worth doing when there's a limit to meet or a real distribution problem, not as routine maintenance.
Does 1MB work for a document with lots of charts?
Yes, and charts hold up well because they're flat color and clean lines rather than photographic detail. It's photographs that consume the budget.
What if I need it under 1MB and it also has to stay searchable?
Not with this tool. Compression works by rebuilding pages as images, so searchable text and a heavily reduced file are mutually exclusive here. Keep the original if both matter.

Other size targets
Different forms cap at different sizes. Each target has its own page, set up for the limit it is named after.
