Exact, not "about right"
Upload portals reject files that are 1 KB over the limit. NeoKit searches for the highest quality that lands inside the range, and checks size, pixels and DPI before you download.
Private by design
Photos, signatures and PDFs are processed on your device. There is no upload button because there is no server to upload to.
Sourced rules
Every exam spec, tax slab and university formula links to its official source with a "last verified" date. If we could not verify something, we say so.
Light on data
Pages are tiny and work on 4G. Heavy PDF code loads only on PDF tools.
