Press kit

PortalPrep gets your photo or document exactly right for the specific thing you’re submitting it to — verified specs, not guesswork, entirely on your phone.

The story

A solo developer got tired of government and corporate portals rejecting files over fine print nobody reads, and built an offline tool that actually knows the rules — no ads, no tracking, no subscription, and one small one-time purchase for the feature that actually needs to exist: redacting sensitive numbers before a document is shared.

What it does

Named presets with specs taken from the official pages — US, UK, Canada and India visa and passport photos, plus a general international fallback, an exam photo and a job-application PDF — instead of a generic size slider.
Enforces the rules that matter: a landscape photo on the UK visa preset is refused because gov.uk requires portrait; Canada is cropped to its exact 2:3 ratio; a photo too small for India’s minimum is caught.
Never alters how a photo looks — no smoothing, no AI background replacement, no lighting changes. It only resizes, crops and compresses, which matters because the US State Department doesn’t accept passport photos changed with software, filters or artificial intelligence.
Redaction that finds card numbers (checked with the Luhn algorithm) and SSN- and account-shaped numbers, then rebuilds PDF pages as flat images so the hidden text is actually gone.
A live gauge showing exactly how close a file is to its limit.
Splits a PDF that can’t fit under a limit into the fewest files that do, instead of just rejecting it — not offered by the passport-photo apps we found.
100% on-device: no account, no analytics, no server. A free companion website does the same photo resizing in the browser without uploading anything.
