Engineering & Verification Standards
Zero-Knowledge Local Computation
Everyday document utilities (compressing photos, merging contracts, decoding tokens, and checking portal limits) should execute on the user's CPU, not on multi-tenant cloud servers. Sensitive identity documents never cross the network.
Authoritative Requirement Verification
All portal dimensions, DPI requirements, and byte ceilings are audited directly against official government, consulate, and enterprise API specifications before publication. No fabricated statistics or automated guesses.
Deterministic, Factual Metrics
Modifyle does not make unsupported marketing claims. If a tool compresses to 20 KB, the engine tests the physical in-memory Blob byte weight and ensures it strictly satisfies portal upload caps.
How Upload Requirements Are Audited
Every requirement preset published on Modifyle (from U.S. State Department passport dimensions to UPSC signature caps and ATS resume parsers) is verified against authoritative primary documentation. We re-audit government consular notices and platform developer guidelines semi-annually. Each specification card displays its exact provenance link, audit date, and verified technical scope.
