PDF Inspector

Dekhiye PDF asal mein kya hai: uska version, save ka itihaas, security handler, page boxes, fonts, forms aur scripts.

Report banane ke liye file isi tab mein byte-dar-byte paDhi jaati hai, aur report page se tab hi bahar jaati hai jab aap use copy ya download karein. Document ke baare mein kuch upload nahin hota.

PDF Inspector ke baare mein

Do files jo screen par ek jaisi dikhti hain bilkul alag vyavhaar kar sakti hain: ek ek hi saaf save hai, doosri par original ke upar aath updates lagi hain, ek purana fast-web-view header hai aur ek aisa font jo kisi aur ke paas nahin. Yeh kacche bytes aur object graph dono ko saath paDhta hai — %PDF header ke saamne catalog ka version, wo end-of-file markers jo har incremental save ki pol khol dete hain, cross-reference classic table hai ya compressed stream, encryption dictionary aur uske permission bits — aur phir page boxes, fonts, images, forms, annotations, bookmarks, attachments, layers aur scripts ek hi report mein rakh deta hai. Yeh aapke device par hota hai, aur jo kuch paDha nahin ja saka use andaaza lagane ki jagah list kar diya jaata hai.

Features

• Version header se aur catalog se, saath mein note jab kisi update ne use baDha diya ho
• Save ka itihaas: end-of-file markers, incremental saves, aur fast web view ab bhi saabut hai ya nahin
• Security handler, cipher aur key size, aur har permission bit khol kar naam ke saath
• Page sizes kaagaz ke naam aur millimetre se grouped, saath mein rotations, UserUnit scaling aur koi bhi trim, bleed ya art box
• Fonts unki embedding sthiti ke saath, alag-alag images, type ke hisaab se form fields aur subtype ke hisaab se annotations
• Bookmarks, naam ke hisaab se attachments, optional-content layers aur wo jagahein jahan JavaScript chhupta hai
• XMP packet se paDhe gaye PDF/A aur PDF/UA ke daave, saath mein tagging aur structure tree
• Poori report ticket ya pre-flight jaanch ke liye JSON ke roop mein copy ya download

Common errors aur troubleshooting

• Reader title dikhata hai par document ki jaankari khaali hai. — Wo strings encrypted hain. Structure, page sizes, fonts aur permissions encrypted hisson ke bahar baithte hain aur ab bhi paDhe jaate hain, par text values nahin — Decrypt PDF se password hataiye aur dobara inspect kijiye.
• Yeh PDF/A-2b dikhata hai par hamara validator file reject kar deta hai. — Wo badge XMP packet ka daava hai, faisla nahin. Yahan colour spaces, fonts aur transparency ke wo niyam dobara nahin jaanche jaate jo conformance test dekhta hai, isliye use jaanchne layak daava maaniye.
• Document catalog mila hi nahin. — Encrypted file mein wo aam taur par kisi compressed object stream ke andar baithta hai, jo password ke bina khulta nahin. Uske upar ki har byte-level baat — version, save ka itihaas, cross-reference ki kism — ab bhi sahi hai.
• Doosre tool se kam objects bataye gaye. — Kharaab objects alag gine jaate hain aur unka content report mein gaDhne ki jagah chhoD diya jaata hai. Repair PDF us file ko dobara bana sakta hai jiske objects parse nahin hote.

Aksar pooche jaane wale sawaal

“3 incremental updates” mujhe document ke baare mein kya batata hai?

Yeh ki use dobara likha nahin gaya, balki original ke upar teen baar save kiya gaya hai. Pichhli sthitiyan ab bhi bytes mein maujood hain, isliye jo content baad mein dhaka gaya wo wapas nikala ja sakta hai, aur file zaroorat se baDi hai.

Kya linearisation aur web ke liye optimised hona ek hi baat hai?

Haan. Linearised file pehla page aage rakh deti hai taaki reader use baaki aane se pehle dikha sake. Yeh bhi jaancha jaata hai ki wo ab bhi saabut hai: incremental save header ko peeche chhoD deta hai, aur phir reader poori file load kar lete hain.

Permissions “allowed” dikhte hain par file phir bhi copy karne kyun nahin deti?

Permission bits reader se ek guzarish hain, content par taala nahin. Unhe yahan bilkul waise khola jaata hai jaise security handler ne store kiya; koi bhi viewer unhe maanta hai ya nahin, yeh us viewer par hai.

Kya report bata sakti hai ki page vector hai ya scan?

Vyavhaar mein bharose se: jis page par koi font na ho aur ek baDi image ho wo scan hai. Content card font ki ginti aur alag-alag images deta hai, jo computer par bane page aur photo khinche page ko alag karne ke liye kaafi hai.

Hybrid cross-reference section kya hai?

Wo file jo classic table aur compressed stream dono le jaati hai, taaki purane aur naye reader dono objects dhoondh sakein. Sabse zyada compatibility ke liye save kiye documents mein yeh saamanya hai.
