File ka asli type, size aur hash dekhe, bina upload kiye, browser mein hi
Sab kuch aapke browser mein hota hai. Koi file upload nahi hoti.File ka naam kuch aur kehta hai aur andar kuch aur nikalta hai, aur portal usse reject kar deta hai bina kaaran bataye. Yahan file daaliye: uske shuruaati bytes aapke apne device par padhe jaate hain, aur aapko batate hain ki file asli mein kis format ki hai, kitni badi hai, photo hai to kitne pixel ki, aur uske saath kaun se tool chal sakte hain.
Koi bhi file yahan daal dijiye - naam aur extension chahe kuch bhi ho.
Format, size, dimensions, metadata aur hash ek saath padh lijiye.
Neeche dekhiye ki is file par is site ke kaun kaun se tool chal sakte hain.
Jis site par ek sau chalis tool hon aur andar jaane ka koi raasta na ho, woh das tool wali site se mushkil hai. Isiliye yeh page aapse tool ka andaaza lagwane ke bajaye file maangta hai aur usi se ulta chal kar jawab nikaalta hai.
Naam aur extension aapke device se aate hain. Format file ke apne shuruaati bytes se aata hai, jinhe us signature table se milaya jaata hai jisse is site ka har format bataya gaya hai - isliye photo.png naam ki JPEG file yahan JPEG hi batai jaati hai. MIME type usi faisle se nikalta hai, aur jahan aapka browser kuch aur kehta ho wahan uska dawa bagal me dikha diya jaata hai. Size insaani aankde me bhi aata hai aur theek bytes me bhi, kyunki upload portal bytes hi ginte hain. Magic number hex me aur akshar me, dono roop me chhapta hai, us offset ke saath jahan woh baitha hai. Chaudai aur oonchai PNG, JPEG, GIF, BMP, WebP, TIFF, ICO, SVG, HEIC aur AVIF ke header se padhi jaati hai, tasveer khole bina, isliye chalees megapixel ki photo bhi turant nap jaati hai. Metadata ka matlab hai EXIF, XMP, IPTC aur andar likha text, us GPS jagah samet jo phone photo me daal deta hai. Hash SHA-256 aur MD5, poore file par.
Jo baat tay na ho use khaali chhodne ke bajaye ek line me likh diya jaata hai. Zip ki koi dimension nahi hoti. Jis JPEG ka metadata hata diya gaya ho usme kuch nahi milta. CSV ka koi magic number nahi hota, kyunki text format me woh hota hi nahi. Jise koi pehchanta hi na ho, uska koi imaandaar MIME type hai hi nahi.
Yahi poora page ka sawaal hai, aur yeh list kahin likhi hui nahi rakhi gayi. Har baar page khulne par registry se nikali jaati hai, yeh padh kar ki har tool khud kya leta hai - isliye agle mahine juda tool yahan apne aap aa jaata hai. Kuch upload nahi hota: pehchanne ke liye pehle 64 KB padhe jaate hain, PDF par taala hai ya nahi yeh dekhne ko aakhri kuch, aur hash chaar chaar MB ke tukdon me liya jaata hai.
File is page par daal dijiye aur uske pehle bytes browser me hi padh liye jaate hain. Kuch install nahi karna padta, file upload nahi hoti, aur format, size, dimensions, metadata aur hash sab ek saath dikh jaate hain. Uska asli format, uske signature bytes aur unka offset, teeno saamne hote hain.
Use yahan daal dijiye. Lagbhag har binary format apni shuruaat me bytes ki ek tay ladi likhta hai, isliye PNG, PDF, zip ya MP4 apne andar se pehchana jaata hai, naam chahe kuch bhi ho. Faisla, uske peeche ke signature bytes aur woh jis offset par baithe hain, sab dikhaye jaate hain.
Naam badalne se sirf label badalta hai, file nahi. JPEG me save ki gayi photo ko baad me .png naam de dene par woh andar se JPEG hi rehti hai, aur jo portal theek se jaanchta hai woh use laut a dega. Yeh page bytes padh kar asli format batata hai aur wahi converter bhi dikha deta hai jo naam ko sach kar de.
Nahi. Format pehchanne aur tasveer naapne ke liye pehle 64 KB aapke apne browser me padhe jaate hain, PDF par taala hai ya nahi yeh dekhne ko aakhri 4 KB, aur hash tukda tukda karke aapke device par hi nikala jaata hai. Kuch server tak nahi pahunchta, isliye baad me kisi se kuch mitwana bhi nahi padta.
Haan - PNG, JPEG, GIF, BMP, WebP, TIFF, ICO, SVG, HEIC aur AVIF ke liye. In sab me chaudai aur oonchai header me likhi hoti hai, isliye number seedha pehle bytes se padh liya jaata hai, tasveer khol kar nahi. Isiliye 40 megapixel ki photo bhi thumbnail jitni tezi se nap jaati hai.
Woh bytes hi woh tareeka hain jisse software bina file ka naam maane format pehchanta hai. PNG 89 50 4E 47 se shuru hoti hai, PDF %PDF se, zip PK se. Unhe hex me dekh lena saabit kar deta hai ki file hai kya - jo tab kaam aata hai jab upload baar baar fail ho raha ho.
Is site ka har tool ek hi registry me khud batata hai ki woh kis tarah ki file leta hai. List har baar page khulne par usi registry se banti hai, kisi haath se rakhi gayi table se nahi - isliye baad me juda tool sahi file ke liye turant dikhne lagta hai aur hataya gaya tool dikhna band ho jaata hai.
Haan. EXIF, XMP, IPTC aur andar likha text JPEG, PNG aur WebP se padha jaata hai, aur GPS ki jagah ek chetavni ke saath dikhai jaati hai. 64 MB se badi file chhod di jaati hai aur page yeh keh deta hai, kyunki itni badi file metadata ke liye chhaanna tab ko jaam kar deta.
