Technical Architecture & In-Browser Processing

Immigration, Refugees and Citizenship Canada (IRCC) enforces a strict 4.0 MB file size limit per document slot. Files at 4.01 MB trigger an immediate portal upload error. FitSize targets 3.85 MB with intelligent vector preservation, ensuring passport stamps, banking letters, and digital AcroForm fields remain unflattened and clearly legible to Canadian visa officers.

Tailored for Canadian visa and study permit submissions, this profile enforces an exact sub-4MB document threshold required by Immigration, Refugees and Citizenship Canada. The processor flattens multi-layer annotations, clears insecure embedded scripts, and ensures biometric and passport scans pass IRCC portal validation checks.
