Combine Marksheets into Single PDF under 500KB (College & Govt Exam Portals)

1University & Government Portal Single-Upload Constraints

Academic admission portals (such as Delhi University CSAS, IIT JEE JoSAA, NEET MCC, and state PSC recruitments) provide only one single document upload slot for educational qualifications, accompanied by strict file size restrictions (typically 'Single PDF under 500KB' or 'Under 300KB'). Applicants who merge multiple high-resolution scans with conventional software inevitably produce 4MB–8MB files that are instantly rejected by the portal.

Furthermore, when candidates upload documents of varying sizes, the resulting PDF contains mismatched page dimensions—some pages appear huge while others are tiny. This can cause verification officers to mark applications as defective.

• Strict Size Constraints: Hard caps at 500KB or 300KB enforced across national counseling portals.
• Readability Mandate: Text, marks, roll numbers, and official board seals must remain crystal clear.
• Chronological Ordering: Portals require 10th class certificates first, followed by 12th, graduation, and category certificates.

Before uploading your combined dossier, consult the exact file size caps and document ordering rules enforced by major admission counseling authorities:

3Uniform ISO A4 Standardization & Adaptive Compression

FileZenith solves both problems simultaneously. First, our engine standardizes every uploaded document onto a uniform ISO A4 page layout (595.28 x 841.89 points) with clean, centered margins, eliminating awkward page size variations. Second, our algorithm applies multi-pass adaptive JPEG stream compression, mathematically balancing typography sharpness and file weight.

The resulting dossier strictly adheres to your chosen limit (under 500KB or 300KB) while ensuring that verification officers can read every grade and signature clearly.

• Uniform A4 Standard: Every single page is formatted to exact A4 dimensions with proportional scaling and zero distortion.
• Target Size Guarantee: Iterative binary quality optimization guarantees the file stays under 300KB, 500KB, or 1MB.
• Interactive Sequence Arrangement: Reorder your certificates chronologically with simple up/down controls.
