Why compress a PDF to 10MB specifically?
Many email clients (Gmail, Outlook) have 10-25MB attachment limits. Cloud storage services and some portals also impose 10MB limits on uploaded documents.
Will the quality be good at 10MB?
Excellent. Our custom mode renders pages at 144 DPI (2× native resolution) and uses lossless PNG encoding where possible, giving you the sharpest output within your size budget.
Can I compress a 50MB PDF to 10MB?
Yes. Upload any PDF up to 50MB, select Custom Compression, and set 10240KB (10MB) as the target. The calibration engine will adjust quality to hit that size.
Is there a batch compress option?
You can add multiple files at once — each file gets its own compression settings and download button.
