Getting under 1MB
- Drop your PDF — the 1 MB target is preselected.
- Click Compress. Images are re-encoded at sensible resolution; text and vectors are untouched.
- Download — you'll see the before/after sizes and the percentage saved.
1MB is usually the easy win
Unlike the brutal 100 KB portals, a 1 MB ceiling leaves room to keep documents looking essentially identical. The oversized PDFs that miss it are almost always carrying camera-resolution images — 4000-pixel photos displayed three inches wide. Scaling those to what the page actually shows routinely cuts 80–95% of the file with no visible change, no rasterizing, and no watermark.
Frequently asked questions
How do I get a PDF under 1MB?
Drop it above — the 1 MB target is preselected. Click Compress and Sleek PDF finds the best quality that fits. At 1 MB most multi-page documents keep excellent visual quality.
What kinds of files need the 1MB limit?
Email attachment policies, LMS and course-portal uploads, tender/procurement systems, and CMS media limits. 1 MB is the roomiest of the common ceilings — usually reachable without any visible quality loss.
My PDF is 50MB of scanned pages. Realistic?
Often yes — high-DPI scans carry far more resolution than reading or printing needs. Re-encoding at sensible resolution regularly shrinks scan-heavy files 10–30×. If standard mode can't reach 1MB, Extreme mode will.
Is there a file size limit on what I can compress?
No imposed limit — processing happens on your device, bounded only by its memory. Above roughly 150MB you'll see a soft warning, and splitting first can help.
