Auto (one long page)
Choose the paper size for the output. Select "Auto" to fit everything onto one continuous page instead of splitting it across pages - useful for viewing on screen.
Portrait
Sets whether PDF pages are portrait or landscape. Choose "Auto" to have the orientation selected for you.
Specify page margins in pixels (maximum 1000).
Specify the browser width in pixels (0 - 10000) to render the page in.
3 second
Seconds to wait before capturing the page (useful if you are capturing a web page that takes time to load)
If enabled, we will attempt to hide cookie notices.
Renders the page using its print stylesheet, the layout a site uses when you print it. This usually drops navigation, ads, and sidebars for a cleaner result, though some sites have no print stylesheet, in which case the page looks the same either way.
Default
Optimizes layout and formatting for a specific e-reader. Choose the one that matches your device.
No
Attempts to detect and correct common styling problems in the source file. Experimental, so check the output before relying on it.
Add margin (0-10 cm)
No Change
The base font size is the size of the bulk of the text in your document. Set it and we rescale every font size proportionately, so the most common size becomes your chosen value and headings, captions, and other text scale with it. Select "No Change" to keep the original sizes.
For example, "Mikhail Gorbachiov" will be replaced by "Mikhail Gorbachiov."
Auto
Sets the character encoding of the input file. Use this if your text shows up as garbled symbols, which happens when a file has no encoding declaration or declares the wrong one. This overrides any encoding declared in the file, so leave it on "Auto" unless you're fixing a specific problem.
Enter a title (maximum 100 characters) for the output file. This is stored in the file's metadata and is what e-readers display in a library list, rather than the filename. Leave it empty to use the source file's title, if it has one.
Enter Author Name, maximum 100 characters

An HTM file is a web page written in HyperText Markup Language — exactly the same thing as an .html file. The shorter extension is a leftover from early Windows and DOS systems, which limited file extensions to three characters, and many older web servers and authoring tools kept the habit. There is no difference at all in the content: browsers treat .htm and .html identically.

 

How to open an HTM file?

Double-click it and the page opens in your default browser. Chrome, Firefox, Edge, and Safari all render HTM without any configuration.

 

To inspect or change the markup, open the file in Visual Studio Code, Notepad++, or any text editor. Saved pages frequently rely on an accompanying _files folder holding images and stylesheets, so keep the two together when moving the page. To archive a page in a fixed layout, use our HTM to PDF tool. You can also convert the file with our HTML to PDF tool.

Electronic Publication (EPUB) is the open standard for e-books and the format used by almost every retailer except Amazon. An EPUB is really a ZIP package of HTML, CSS, images, and fonts, which means the text reflows to fit whatever screen it is read on. Readers can change the font, size, and margins freely, and the same file works on phones, tablets, e-readers, and computers.

 

How to open an EPUB file?

On Apple devices, EPUB opens directly in Apple Books. On Windows and Android, Calibre is the standard choice and doubles as a library manager and converter.

 

Other good readers are Adobe Digital Editions, which handles DRM-protected library loans, plus Thorium Reader, Google Play Books, and Kobo. Amazon Kindle devices now accept EPUB through Send to Kindle, but for older Kindles convert the file first with our EPUB to MOBI tool.
