Image format error kyun aata hai?
Kaafi portals sirf specific image formats accept karte hain. Aapke paas PNG hai aur portal sirf JPEG maangta hai — ya WEBP hai aur portal reject kar raha hai. Format convert karna fastest solution hai.
- Government portals: mostly JPEG/JPG accept karte hain
- WhatsApp stickers: WEBP format
- Website images: WEBP for better performance
- Printing: JPEG ya PNG preferred
Formats mein kya fark hai
| Format | Best for | Compression |
|---|---|---|
| JPEG/JPG | Photos, govt forms | Lossy — smaller size |
| PNG | Logos, transparent images | Lossless — larger size |
| WEBP | Web images | Better than JPEG at same quality |
Rule of thumb
Government portals ke liye hamesha JPEG use karein. PNG transparent background ke liye best hai (signature, logo). WEBP modern websites ke liye — lekin govt portals pe avoid karein.
Format change karne par quality kharab hoti hai?
PNG se JPEG — thodi quality loss possible hai (lossy). JPEG se PNG — no quality change (PNG lossless hai). JPEG/PNG se WEBP — minimal quality loss, much smaller size.
