He aha te DPI e whakarārangi ana te PNG?

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.

E tautoko ana te huaputa PNG i te mārama?

Ko te āhua o te āhua, engari kāore he pūtake ā-arawhiti hei hoatu ki a ia — he tino mārama ngā tāruatanga ataata me ngā pātaka i whakawāteatia e te āhua, nā reira ka tae mai ia pikitia ki te mārō. He tino whai hua tonu te kanikani ā-arawhiti i muri mai: ko te tikanga ka taea e koe te whakaiti i tētahi kaupapa mai i te PNG i muri ake, kāore i te huri i te āhua. Ko PNG te kōwhiringa tika mō ngā whakaahua mata, ngā tohu, ngā toi raina me ētahi atu mea me ngā taitapa mārō, mārama rānei — kāore he whakawhāiti, kāore he tae.

He nui rawa te PNG o nga faila?

He nui ake i te mea e tūmanako ana koe, nā te mea ka pupuri te PNG i ia pikitia kia tika, kaua e tata. Ko te 1080p e noho tonu ana i te 2-5 MB, ā, ko te 4K e noho tonu ana i te 6-15 MB, nā reira ka tere te tāpiri i te whakawāteatanga roa. Ko te hokohoko tika tonu tēnei ina kai te whakaahua i te whakamātautau anō, ā, ko te mea hē ina haere hāngai ki tētahi pou tītaka. Ka whakamahia e PNG te whakawhāititanga DEFLATE i runga i ngā raina tātari tātari, kia ora ai ia pikitia, tae atu ki tētahi kanikani ā-arawhiti 8-biti.

Ka taea te kimi te taha PDF o tēnei tahuritanga?

E whakawhirinaki ana katoa ki te āhua o te kupu tūturu. Ko te PDF i hangaia mai i tētahi tuhinga e mau ana i tētahi apa kupu tūturu, ā, ka taea te kimi; he PDF i hangaia mai i ngā karapa, i ngā whakaahua rānei he whakaahua o te kupu, ā, kāore, tae noa ki te OCR e tāpiri ana i tētahi apa. /pdf-ocr/ e mahi ana, ā, e tika ana kia haere i mua i tētahi tahuritanga e tūmanako ana kia whakaakona ngā kupu.

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.

Ka pupuri te PNG i te kaha o te rapu i te PDF kupu?

Kāore — ka huri te rasterizing PDF ki PNG i te kupu ki ngā ira. Mēnā e hiahiatia ana he huaputa e rapu ana, ka pupuri te PDF hei PDF, ā, ka whakamahia tētahi utauta whakawātea kupu. Ko te huaputa whakaahua (PNG) hei whakaaturanga ā-whakaahua, hei whakamātautau whakaahua rānei.

He aha mo ngā papamuri mārama i roto i te 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.

He maha te wā e PDF ki PNG hei tuhinga 100-pātaka?

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.

He aha te rahi o te pūrākau o tētahi pūrākau 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.

Ka taea e au te whakakotahi i ngā tīwae katoa PDF ki roto i tētahi whakaahua tiketike PNG?

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.

He tūmataiti ahau PDF i te wā o te tahuritanga 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.
