InkDiet – Save Printer Ink

The grey background in your scans costs ink at the printer. InkDiet pulls it to white — and shows you how much you saved.

Phone scans look fine on screen and eat ink on paper. The culprit is the grey background: shadows, paper tone, sensor noise. You barely notice it on a display, but your printer puts every shade of grey on the page.

InkDiet removes exactly that. Photograph the page and the app pulls the background to clean white while keeping text and lines intact. You see what you saved right away — as a percentage for each document and as a running total on the home screen.

HOW IT WORKS • Photograph a page or pick one from your gallery • Check the corners — edges are detected automatically, the loupe helps you fine-tune • Pick a filter: Soft, Strong or Colour (no filter) • Compare before and after side by side, zoom in on the detail • Save, export as PDF, share or print

WHAT YOU GET • Perspective correction — a page shot at an angle comes out straight • Three filter strengths with an adjustable slider • PDF in A4, Letter or A5 at 150, 300 or 600 dpi • Merge several pages into a single PDF • Pen, box and text for quick markup • Print directly via AirPrint

YOUR SAVINGS, YOUR PRINTER What a saved page is worth depends on your printer and your cartridge. That is why you set the ink cost per page yourself — the euro figure in the app is an estimate based on that number, not a measurement.
