About this tool
Make a PDF cheaper and clearer to print. Choose grayscale to keep the shades, or black and white for sharp text on scanned pages. Each page is turned into a picture, so the text can no longer be selected. Works in your browser, up to 150 pages.
When to use it
Turn a colour PDF into grayscale or pure black and white for cheaper printing or a cleaner scan.
Tips
Black and white works for text documents. Grayscale keeps photos readable.

Vidokezo vya matokeo bora
Fanya kazi na nakala ya faili yako na uhifadhi ya asili hadi uangalie matokeo. Kabla ya kuituma kwenye lango, mwajiri au taasisi, fungua matokeo na uangalie kila ukurasa. Ikiwa kuna kikomo cha ukubwa, angalia jinsi tovuti inayopokea inavyokipima: baadhi huhesabu kilobaiti moja kama baiti 1000, wengine kama 1024. Usindikaji wote hufanyika kwenye kichupo cha kivinjari kwenye kifaa chako mwenyewe, kwa hivyo faili kubwa hutegemea kumbukumbu ya kifaa na zinaweza kuchukua muda zaidi kwenye simu.
