Izithombe ezinzima ze-PDF zilahlekelwa yi-40-75% yobukhulu babo. Ukuphuma okulinganiselwe kubonisa ngokuzenzakalela ngaphambi kokulethela.

Isicindezeli se-PDF - FAQ
Nciphisa ubukhulu behele le PDF ngaphandle kokuwuphula. Sisebenzisa i-Ghostscript ukuncipha kwezithombe ezifakwe ngaphakathi kanye nefonti ezisetshenzisiwe - izilungiselelo ezingaphambili ezingu-3 zobubanzi: Isikrini (72 DPI, okuncane kakhulu kwi-web), i-eBook (150 DPI, elinganiswe), Iphrinta (300 DPI, iphrinta-elungele ngokulimala okuncane). Ubukhulu obulinganiselwe bokuphuma bubonisana ngaphambi kokuba ucindezele ukucindezela.
500 tokens for Screen, 750 for eBook, 1,000 for Print — flat ngadokhumende kuze kube yi-50 MB, akukho zindleko ngekhasi ngalinye. Abasebenzisi abamahhala bathola ama-6,000 ansuku zonke atholakale ngakho-ke izingcindezi eziningi zimahhala. Akukho izingcindezi ze-MB ngayinye — ukucindezela i-2 MB noma i-50 MB PDF izindleko ezifanayo.
Kuxhomekeka emthonjeni. Izithombe ezinzima ze-PDF zincane ngo-60-80% kwi-Screen futhi 40-60% kwi-eBook. Izithombe ze-PDF ezibhalwe kuphela ezikhona ngokunethezeka zincane ngo-5-15% ngoba akukho sithombe esiningi esidinga ukufakwa ngezansi. Sibonisa ubukhulu obulinganiselwe bokuphuma ngokuya ngekhwalithi emiselwe ngaphambili okhetha yona.
Isikrini: 72 DPI umbala + izithombe zesikali esimnyama, isethulo sefonti, ukwenziwa kwe-web - yenziwe ngemboniso yesikrini. i-eBook: 150 DPI, efundeka kumafoni namathebulethi. Phrinta: 300 DPI, igcina ama-vector paths angekho, igcina umbala we CMYK - iphephile ukuphrinta okunekhono.
Yebo - i-Ghostscript iphinde isampule izithombe ku-DPI efanele (kungaphansi), iqoqe ngezansi ifonti ku-glyphs kuphela esetshenziswa ngokusemthethweni, futhi igcine ama-vector paths angekho emthethweni. Isikrini esisetshenzisiwe singabonakalisa ngokulula uma sizongeza ngaphezu kuka-200% ngoba i-pixel data iphansi; sebenzisa i-eBook noma iphrinta ukugcinwa.
50 MB. I-PDF enkulu (amabhuku ashicilelwe, ama-blueprints esakhiwo), hlukanisa kuqala ku /pdf/split/ zibe yizingxenye ezincane, cindezela ngayinye, bese uhlanganisa ku /pdf/merge/.
Compressing a signed PDF breaks the cryptographic signature because we re-serialize the file. Sign after compressing if the signature matters. For signed contracts that need to stay valid, use Print quality and skip recompressing - or compress the source first, then resign.
Siyeka amafayela abhalwe ngekhodi - i-Ghostscript izokhipha ngokuzithandela i-PDF engenanto. Vula kuqala ku /pdf/unlock/ uma unedokhumende. Uma kucindezelwe, ungaphinde ugcine ku /pdf/protect/.
Akunalutho. Ukucindezela kusebenza kuseva yethu ye-API usebenzisa i-Ghostscript + pikepdf endaweni. Ifayela libhalwe kufolda yesikhathi, licindezelwe, futhi umthombo ususwa. I-output ihlala kwi-CDN yethu amahora angama-24 (amasonto angama-7 ngemali esebenzayo).
Free.ai imahhala. I-Adobe Acrobat Pro ($ 19.99 / mo) isebenza njenge-distiller yokucindezela. I-Smallpdf ($ 9 / mo) isebenzisa ukucindezelwa kwe-cloud yabo. Sibonisa / v1 / pdf / compress / nge-API yasekhaya - abanye babeka i-gate yabo ngemuva kokuthengiswa kwebhizinisi.
Akunakuchofoza ngalinye - thumela ngalinye ngasikhathi sinye. Ukwenza amaqembu ngokuzenzakalela, sebenzisa i /v1/pdf/compress/API endpoint ne loop kushicilelo lwakho. Ucingo ngalunye lubiza izindleko ezijwayelekile ezibekwe ngaphambili.
Yebo - POST ingxenye eminingi ku /v1/pdf/compress/ ngefayela + ubuningi (isithombe / ebook / printer). Cindezela isiphetho /v1/pdf/compress-quote/?quality=Q&input_size=B ibuyisela izindleko + ubukhulu obulinganiselwe bokuphuma. I-curl recipe ephelele ku /api/.
