Aksar Puche Jane Wale Sawaal (FAQs)

Kya free DPI converter ka istemal safe hai?

Haan, zyadatar top online tools aapki image ko sirf aapke browser (locally) mein hi process karte hain aur unhe kisi bahari server par save nahi karte. Phir bhi, highly sensitive documents upload karne se pehle us website ki privacy policy ek baar zarur padh lein.

DPI aur Image Resolution mein kya farq hota hai?

Resolution ka matlab image ki height aur width pixels mein (jaise 1024×768) hota hai. Wahi DPI (Dots Per Inch) yeh batata hai ki jab photo physically print hogi, toh ek inch ke area mein kitne dots (pixels) print aayenge. Higher DPI ka sidha matlab behtar aur sharp print detail se hota hai.

UPSC aur SSC form ke liye photo ka size aur DPI kya hona chahiye?

Aam taur par SSC CGL ke liye photo ka size 20KB-50KB aur resolution 100x120px ya 3.5cm x 4.5cm hona chahiye. UPSC ke liye photo aur signature ka size 20KB se 200KB ke beech manga jata hai. Scanned image clear honi chahiye, jiske liye 200-300 DPI best maana jata hai.

Kya mobile phone se image ka DPI badla ja sakta hai?

Bilkool! Mobile phones (jaise iPhone ya Android) me default option nahi hota, lekin aap apne mobile browser (Chrome, Safari) se kisi bhi free online converter website ko open karke direct apni gallery se photo upload kar sakte hain aur naya DPI set kar sakte hain.

Agar meri photo pehle se blur hai, toh kya DPI badhane se woh theek ho jayegi?

Nahi, DPI badhane se koi bhi purani blur photo automatically clear ya HD (sharp) nahi hoti. DPI sirf printing ke dauran print ki density ko control karta hai. Agar aapki original photo ki quality hi kharab hai, toh nayi clear photo click karna hi sabse behtar option hai.
