PDF pou PNG FAQ sou Konvèsyon
Ki DPI PNG a ap renderize a?
+
The Resolution menu on the converter page offers 72 DPI for screen use, 150 DPI, which is the default, and 300 DPI for print. Higher resolutions give sharper but larger PNG files.
Èske PNG rezilta a sipòte transparans?
+
Format la fè sa, men sous la pa gen alfa pou bay li — kadr videyo ak paj renderized yo konplètman opaque pa nati, konsa chak pixel rive solid. Kanal alfa a toujou itil apre sa: li vle di ou ka koupe yon objè soti nan PNG pita san yo pa chanje fòma a ankò. PNG se chwa ki dwat pou screenshots, logos, line art ak nenpòt ki bagay ak bò difisil oswa transparans — pa gen anpoul, pa gen koulè bande.
Ki gwosè PNG dosye yo pral?
+
Pi gwo pase sa ou ta ka espere, paske PNG kenbe chak piksèl egzakteman piske li pa apwòch. Yon 1080p toujou rive nan 2-5 MB ak yon 4K toujou nan 6-15 MB, se konsa yon long kouri ekstraksyon ajoute rapidman. Sa se trade a dwa lè imaj yo manje plis pwosesis, ak sa ki mal lè yo ale dirèkteman sou yon paj entènèt. PNG itilize DEFLATE konpresyon sou filtre scanlines, se konsa chak pixel rete egzakteman, plis yon plen 8-bit alfa kanal.
Èske PDF pati nan konvèsyon sa a ka chache?
+
Sa depann de si gen yon tèks reyèl. Yon PDF ki fèt soti nan yon dokiman gen yon kouch tèks reyèl epi li ka chèche; yon PDF ki fèt soti nan scans oswa imaj se yon imaj tèks e li pa, jiskaske OCR ajoute yon kouch. /pdf-ocr/ fè sa, e li vo kouri anvan nenpòt konvèsyon ki espere li li mo yo.
Can I convert only some pages of the PDF to PNG?
+
The Pages menu has two choices: all pages, which is the default, or the first page only. There is no way to type in a page range. For other pages, split the PDF into single pages with /pdf-split/ and convert the pages you need.
Èske PNG pral kenbe PDF pou ka chèche tèks?
+
Pa — rasterizasyon PDF pou PNG vire tèks an piksèl. Si ou bezwen yon rezilta ki ka chache, kenbe PDF kòm yon PDF epi sèvi ak yon zouti pou ekstraksyon tèks. Rezilta imaj (PNG) se pou yon afichaj vizyèl oswa pou plis pwosesis imaj.
Ki sa ki sou backgrounds transparan nan PNG?
+
Pages are rendered onto a white background, so image formats such as PNG and JPG have no transparent areas, even where the page in the PDF has no fill.
Ki sa ki tan PDF a PNG pran pou yon dokiman 100-pajè?
+
There is no fixed figure: it depends on the number of pages, the resolution you choose and how busy the servers are. A long document at 300 DPI takes noticeably longer than the same document at 72 or 150 DPI, and converting only the first page is the quickest option.
Ki sa ki se gwosè a nan yon paj PNG?
+
It depends on what is on the page and on the resolution. Pages with photos or shaded backgrounds give larger files than pages of plain text. Doubling the resolution gives four times as many pixels, so a page at 300 DPI is much larger than the same page at 150 DPI.
Èske mwen ka fusion tout PDF paj nan yon sèl gwosè PNG imaj?
+
Not on this page: each page becomes its own PNG. To join them into one tall image, download the pages and add them to /image-merge/, which stacks images from top to bottom.
Èske PDF mwen prive pandan konvèsyon PNG?
+
Yes, under the same rules as every conversion: no human review, and the PDF and the rendered images are deleted automatically about 24 hours after conversion.
