How to convert AFPUB to WebP

  1. Add your AFPUB publications

    Drop AFPUB (Affinity Publisher) files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.

  2. WebP is already chosen

    Press Convert. Open Options first if you want to change the defaults. The work happens in this tab.

  3. Download

    Save the WebP, or download everything as one ZIP if you converted several files.

Why ToAny

  • Private by construction

    The AFPUB to WebP converter is part of this page and runs inside your browser. Your publications are never sent to ToAny or to anyone else.

  • No upload, no queue

    Nothing has to travel to a server and back, so the conversion starts the moment you press Convert, even on a slow connection.

  • Free, without an account

    No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.

AFPUB to WebP: what to expect

AFPUB opens only in Affinity, so a printer, a client or a website cannot use it without an exported file. WebP is smaller than JPG or PNG at similar quality and keeps transparency. AFPUB is at home in books, magazines, brochures and other multi-page layouts that are still being edited; WebP is the usual choice for images on websites.

The defaults suit most files. Under Options you can set the quality, aim for a target file size and resize the result.

The WebP encoder is a WebAssembly module that downloads the first time you convert to WebP and is cached afterwards.

AFPUB vs WebP

AFPUB

Affinity Publisher document

AFPUB is the project file of Affinity Publisher, Serif's page-layout app. It holds pages, master pages, text frames, linked images and styles for documents such as brochures, magazines and books. ToAny reads the preview picture Affinity saves inside the file, so what you get is Affinity's own render of the document, at the size Affinity stored it (up to about 512 pixels on the long side), not the layers or the full-size artwork. For a multi-page publication only the single preview Affinity chose to save is available.

WEBP

WebP image

WebP is Google's image format for the web. It is typically a quarter to a third smaller than JPG or PNG at similar quality and supports both transparency and animation. Browsers handle it well; older editors, printers' portals and some messaging apps do not.

Questions

Are my publications uploaded anywhere?

No. The AFPUB to WebP conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.

Does converting AFPUB to WebP reduce quality?

A little: ToAny writes WebP in its lossy mode, so a small amount of detail is traded for a much smaller file. At the default setting the difference is hard to notice. You can raise the quality under Options; there is no lossless setting.

Can I convert several AFPUB files at once?

Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.

How do I convert AFPUB to WebP on Windows, Mac, iPhone or Android?

The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the AFPUB file, press Convert and save the WebP. There is nothing to install.

Is there a file size limit?

Pictures of up to 120 megapixels are accepted (for example 12,000 by 10,000 pixels); a larger one is refused with a message. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
