To compress a PDF to 1MB, add the file below, use the Balanced level, and download the smaller copy. One megabyte is the most common upload ceiling on the web, and nearly every document reaches it without visible quality loss. processed privately in your browser.
Countless web forms cap attachments at 1MB: HR systems, insurance claim uploads, property portals, CRM attachments. Even large reports with photos usually compress below 1MB at Balanced level, because most PDF weight is unoptimized images and duplicate embedded fonts that compression removes losslessly first.
A 50 to 100MB scanned book or brochure may need the Aggressive level to get under 1MB, and extremely long documents may not fit at any quality. In that case, split the PDF into logical parts. chapters or sections. and compress each part under 1MB.

Save your compressed PDFs - up to 90% smaller
Typical reductions are 50 to 90%. Image-heavy files shrink the most; already-optimized PDFs shrink the least. You see the exact before-and-after size instantly, and nothing counts against a quota.
No hard limit. processing happens on your own machine, so capacity depends on your device rather than a server plan. Files of several hundred megabytes work on a typical laptop.
The standard engine preserves form fields. A digitally signed PDF, however, will have its signature invalidated by any modification. compress before signing, not after.
