InkDiet

That grey background is costing you ink.

Phone scans look fine on screen and eat ink on paper — shadows, paper tone, sensor noise. InkDiet pulls the background to clean white and leaves your text and lines intact.

Features

From a crooked photo to a page worth printing

Take the shot, confirm the corners, done. You see what the app removes before you commit — and it works out what you saved.

Background gone

Three settings: soft, strong, or colour with no filter at all. You control the strength.

Perspective fixed

Edges are detected automatically. A page shot at an angle comes out straight.

Before and after

Drag the divider, zoom in, check the detail — before anything is saved.

PDF and printing

A4, Letter or A5 at 150 to 600 dpi. Merge several pages into a single PDF.

Savings in real money

You set what a printed page costs you. The app estimates the amount from that.

Markup

Pen, box and text straight on the result — no detour through another app.

Privacy

Your scans stay on your device

All image processing runs locally on your phone. There is no server to upload scans to and no account to create. The app is ad supported, so it asks for your consent on first launch. The details are in the privacy policy.
