Compression result
—
Image-based compression — text-only PDFs par size kam nahi hota. File kabhi upload nahi hoti.
How it works
Compress PDF dabate hi pdf.js (CDN se lazy-load) har page ko image ki tarah render karta hai — Low par 1.5× scale, Medium par 1.0×, High par 0.7× — phir JPEG quality (0.85 / 0.75 / 0.60) ke saath jsPDF (CDN se lazy-load) in images se nayi PDF banata hai. Pehle/ baad ka size result me dikhta hai aur compressed file download ho jati hai.
Honest limits
- Image/scanned PDFs par best kaam karta hai. Text-only PDFs me pehle se hi text vector hota hai — unhe image banane par file badh bhi sakti hai; result me saaf dikhega.
- Compression ke baad PDF ka text selectable/searchable nahi rehta (pages images ban jate hain).
- Libraries pehle click par CDN se load hoti hain — internet chahiye. PDF kabhi upload nahi hoti, sab browser me hota hai.

Frequently asked questions
Kya meri PDF upload hoti hai?
Nahi. Poora kaam aapke browser me hota hai — file kabhi kisi server par nahi jati.
Kaunsa level choose karun?
Medium zyadatar cases me sahi hai. Print ke liye Low (best quality), sirf WhatsApp/email par bhejne ke liye High (smallest size).
Compressed PDF ka text select kyun nahi ho raha?
Compression pages ko images me badal deta hai — isiliye text selectable/searchable nahi rehta. Ye image-based compression ki limit hai.
File aur badi ho gayi — kyun?
Text-only PDFs par image-based compression kaam nahi karti; unhe chhune se file badh sakti hai. Result me before/after size isiliye dikhaya jata hai.
Kitni baar compress kar sakta hoon?
Jitni baar chahein — par har round me quality thodi girti hai. Ek baar me sahi level choose karna behtar hai.
