Umcimi we PDF - FAQ

Nciphisa ubungakanani befayili ye PDF ngaphandle kokuyiphula. Sisebenzisa i-Ghostscript ukunyusa ezantsi imifanekiso efakwe ngaphakathi kunye nefonti ezimiselwe phantsi — izimiselo eziphambili ezithathu zomgangatho: Ikhusi (72 DPI, encinci kakhulu kwi-web), i-eBook (150 DPI, elungelelanisiweyo), Shicilela (300 DPI, ilungile-ukushicilela nolahleko oluncinci). Ubungakanani bemveliso obuqikelelwayo bubonisiwe phambi kokuba ucofe uxinzelelo.

500 ye-token ye-Screen, 750 ye-eBook, 1,000 ye-Print — i-flat ngamaxwebhu ukuya kwi-50 MB, akukho tyala kwiphepha ngalinye. Abasebenzisi abakhululekileyo bafumana i-6,000 ye-token yosuku ngalunye ukuze ininzi ye-compressions ikhululekile. Akukho xabiso le-MB nganye — ukucofa i-2 MB okanye i-50 MB PDF ibiza ngokufanayo.

Ixhomekeke kumboneleli. I-PDFs ezinombhalo omninzi zincipha nge-60-80% kwiSkrini ne-40-60% kwincwadi ye-e. I-PDFs zombhalo kuphela ezisele zilungiswe kakuhle zincipha nge-5-15% kuba akukho data eninzi yomfanekiso ongayikhuphi. Sibonisa ubungakanani bemveliso obuqikelelwayo ngokusekwe kwixabiso elimiselweyo okhethayo.

Ikhusi: 72 DPI umbala + imifanekiso ye grayscale, iqela elincinci lefonti, i linearize ye web - icwangciswe ukujonga phambi koshicilelo lwekhusi. incwadi ye- e: 150 DPI, efundeka kwifowuni ne tablet. Shicilela: 300 DPI, igcina iindlela ze vector ezingalahlekiyo, igcina umbala we CMYK - ikhuselekile kushicilelo oluzimeleyo.

Ewe - i-Ghostscript ibuyisela imifanekiso kwi-DPI emiselweyo (akukho ngaphantsi), imisela iifonti kuphela kwii-glyphs ezisetyenziswayo, kwaye igcina iindlela ze-vector ezingalahlekiyo. Isikrini esimiselweyo singabonakalisa ngokulula kwi-zoom ngaphezulu kwe-200% kuba i-pixel data ilahlekile; sebenzisa i-eBook okanye Shicilela ukugcina.

50 MB. Ii-PDFs ezinkulu (iincwadi ezixhotyiswe nge-scanner, i-blueprints yokwakha), yahlula kuqala kwi /pdf/split/ ibe zii-batch ezincinci, uxinzelelo ngalunye, emva koko udibanise kwi /pdf/merge/.

Ukutyikitya i-PDF etyikityiweyo kuphula utyikityo lwe-cryptographic kuba siphinda siphinde siqhubekeke kwifayili. Tyikitya emva kotyikityo ukuba utyikityo lubalulekile. Kwimimiselo etyikityiweyo efuna ukuba ihlale isebenza, sebenzisa Umgangatho woShicilelo kwaye ushiye utyikityo kwakhona — okanye utyikitye umbhalo kuqala, emva koko ushiye.

Siyiyeka iifayili ezifihliweyo - i-Ghostscript izakuvelisa ngokusisigxina i-PDF engenanto. Vula kuqala kwi /pdf/unlock/ ukuba uphethe uxwebhu. Xa ucinezelwe, ungaphinde ukhusele kwi /pdf/protect/.

Hayi. Uxinzelelo luyasebenza kwiseva yethu ye API usebenzisa i Ghostscript + pikepdf ngaphakathi. Ifayile ibhalwe kulawulo lwexeshana, ixinzelelwe, kwaye umbhalo ucinywe. Imveliso ihlala kwi CDN yethu yeeyure ezingama- 24 (iintsuku ezisixhenxe nge credits ezisebenzayo).

Free.ai isimahla. I-Adobe Acrobat Pro ($ 19.99 / mo) iqhuba i-distiller yokucinezela efana nayo. I-Smallpdf ($ 9 / mo) isebenzisa ukucinezela kwecloud yabo. Sibonisa / v1 / pdf / compress / nge-API yomphakathi - abanye i-gate yabo ngasemva kwentengiso yeshishini.

Ayikucofa elinye kuphela - thumela nganye ngaxeshanye. Kwiziqulathi zeefayili ezizenzekelayo, sebenzisa /v1/pdf/compress/ API indawo yesiphelo kunye ne loop kwiskripti sakho. Unxulumano ngalunye lubiza ixabiso elithe nkqo le-preset ngokukodwa.

Ewe — UTHENGA inxalenye eninzi kwi /v1/pdf/compress/ ngefayili + umgangatho (ikhusi / incwadi ye-e / umshicileli). Inqaku lesiqendu /v1/pdf/compress-quote/?quality=Q&input_size=B libuyisela ixabiso + ubungakanani obuqikelelwayo bemveliso. I-curl recipe epheleleyo kwi /api/.
