PDF i EPUB Cwestiynau Cyffredin Trosi
Sut ydw i'n troi llawysgrif PDF yn e-lyfr EPUB cyhoeddadwy?
+
Upload the PDF and the converter builds a reflowable EPUB from it: the text re-wraps to fit any screen and font size, chapter headings become a clickable table of contents, and the book opens in Apple Books, Kobo, Google Play Books and most reader apps. Kindle Direct Publishing also accepts EPUB uploads. The converter works with the structure your PDF already has, so read through the result before you publish it.
A fydd y EPUB yn ail-lifo'n iawn ar ffôn neu ddarllenydd e-bost?
+
Dyma'r peth pwysicaf y byddwch yn ei ennill. Mae gan PDF dudalennau gosodedig, felly mae sgrin fach yn lleihau'r dudalen gyfan neu'n gorfodi sgrolio llorweddol. Mae'r EPUB yn cadw testun fel testun, felly mae'r darllenydd yn ei ail-droi i unrhyw led sgrin a maint wynebfath. Mae cynlluniau aml-golofn a thabl mawr yn lle mae ail-droi yn cael trafferth - dyma'r rhannau sy'n werth eu gwirio ar ôl trawsnewid. Mae EPUB yn ail-llifogi testun i unrhyw faint sgrin a unrhyw faint wynebfath, sy'n ei gwneud yn ddarllenadwy ar ffôn a darllenydd e-bost.
Beth os yw'r ffynhonnell yn argraffiad heb unrhyw destun gwirioneddol ynddo?
+
Wedyn, mae'r trawsnewid yn creu llun o'r testun yn hytrach na'r testun ei hun, ac nid yw chwilio amdano'n dod o hyd i unrhyw beth. Rhedeg /pdf-ocr/ i ychwanegu haen testun a adnabyddir yn gyntaf; mae adnabyddiaeth nodau optegol yn troi'r picseli a arsylwir yn nodau dewisiadwy a chywiradwy y gall y trawsnewid eu cludo drwy'n iawn.
A allwch chwilio am ochr PDF y trawsnewid hwn?
+
Mae'n dibynnu'n llwyr ar a oes testun gwir yn bresennol. Mae PDF a gynhyrchir o ddogfen yn cario haen testun gwirioneddol ac mae'n chwilioadwy; PDF a gynhyrchir o arsylwadau neu ddelweddau yw llun o destun ac nid yw, nes ychwanega OCR haen. Mae /pdf-ocr/ yn gwneud hynny, ac mae'n werth rhedeg cyn unrhyw drawsnewid sy'n disgwyl darllen y geiriau.
A yw'r trawsnewidydd yn canfod pennod yn fy PDF yn awtomatig?
+
It follows the structure of the file. In a Word document, paragraphs styled as Heading 1 and Heading 2 become the chapters, and in Markdown the # and ## headings do the same. In a PDF or a plain text file there are no heading styles, so the converter looks for lines that read like chapter titles, such as Chapter 3 or Part Two. There is no setting for defining chapters yourself, so consistent headings in the PDF give the best EPUB.
A fydd gan y EPUB dabl cynnwys cliciadwy?
+
Yes, built from the chapters the converter finds. Reader apps show it in their contents menu, so a reader can jump straight to any chapter. A PDF with no headings and no chapter titles produces an EPUB whose contents list is short or empty, which is the main thing to check before publishing.
Does the EPUB get a cover image?
+
Yes. If a Word document starts with a picture, that picture becomes the cover of the EPUB. Otherwise the converter generates a plain cover showing the title and author, so the book still has a thumbnail in reader libraries. Markdown files are the exception and come out without a cover. There is no separate cover upload: to use your own artwork, place the image at the very start of the Word document before converting.
How do I set the title and author of the EPUB?
+
Set them in the PDF before you upload, because the converter copies the title and author stored in the file. In Word, fill them in under File, Info, Properties; in Markdown, add a YAML block with title and author at the top; a PDF uses its own document properties. A plain text file stores none, so its file name becomes the title. There is no metadata form on this site, so details such as an ISBN or publisher are added afterwards in an ebook editor like Calibre or Sigil, or in the store upload form.
Beth am ddelweddau a delweddau yn y PDF?
+
Pictures placed in a Word document are carried into the EPUB at the same point in the text. From a PDF, embedded images are extracted where the converter can find them, but charts and diagrams drawn as vector shapes may not come across, so check those pages. A Markdown file is uploaded on its own, so images it points to on your computer cannot be included. A plain text file has no images.
Does the EPUB keep my PDF formatting (italics, bold, quotes)?
+
Italic and bold text carry across. Straight quotation marks are turned into curly typographic ones and double hyphens into proper dashes, so the EPUB reads like a typeset book. Page size, margins and page numbers are not kept, on purpose: a reflowable EPUB has no fixed pages, and each reader app lays the text out for its own screen.
A allaf wneud y EPUB yn gydnaws â Kindle a darllenwyr eraill?
+
The EPUB opens directly in Apple Books, Kobo, Google Play Books and most Android and desktop reader apps, and Kindle Direct Publishing accepts EPUB files for publishing. To read it on a Kindle, send the EPUB with Amazon's Send to Kindle service, or convert it to AZW3 at /epub-azw3/ for older models.
A yw fy PDF llawysgrif yn breifat yn ystod y trawsnewid EPUB?
+
Yes. Your PDF is processed on our own conversion servers and is never shared with anyone or used to train any model. The uploaded PDF and the finished EPUB are deleted automatically about 24 hours after the conversion, which leaves you time to download the result. The full policy is at /privacy/.
