Free online PKPASS to WEBP converter

Source format: pkpass

PKPASS is the file format used by Apple Wallet for digital passes such as boarding passes, event tickets, coupons, loyalty cards, and store cards. A PKPASS file is usually a signed package that contains images, pass data in JSON, and metadata needed for Wallet to display and verify the pass. It is commonly created by airlines, venues, retailers, and developers who distribute passes to iPhone and Apple Watch users.

Because PKPASS is a pass container rather than a simple image format, it is not meant to be edited like a photo. If you want to convert it to an image format such as WEBP, the usual goal is to extract or render the pass artwork for previewing, archiving, or sharing.

Target format: webp

WEBP is a modern image format developed by Google. It supports lossy and lossless compression, transparency, and smaller file sizes than many older formats at similar visual quality. WEBP is widely used on the web, in apps, and in content workflows where efficient image delivery matters.

Compared with a pass package like PKPASS, WEBP is a single image file, so it is useful when you need a static visual representation of the pass rather than a functional Wallet pass. It is a good choice for thumbnails, previews, and web publishing.

How to perform the conversion

There is no direct one-click conversion from PKPASS to WEBP in most desktop apps because PKPASS is a signed pass bundle. The practical workflow is to extract the pass artwork and then save or convert that image to WEBP.

1. Open or unpack the PKPASS file. A PKPASS file is essentially a ZIP-based package. You can rename pass.pkpass to pass.zip and extract it with a file archiver such as 7-Zip, WinRAR, or the built-in archive tool on your system.
2. Locate the image you want to convert. Inside the package, look for files such as thumbnail.png, icon.png, logo.png, or background artwork referenced by the pass. These are usually PNG images.
3. Choose the best source image. For a WEBP preview, the most useful file is often the main background or thumbnail image, depending on how the pass is designed.
4. Convert the extracted image to WEBP. Use an image editor or converter that supports WEBP, such as GIMP, ImageMagick, or Photoshop with WEBP support. For example, with ImageMagick you can run magick input.png output.webp.
5. Verify the result. Open the WEBP file in an image viewer or browser to confirm that the image looks correct and that transparency, cropping, and colors are preserved as expected.

If you only need a quick preview and do not want to install software, you can convert the file on 101convert.com for free, without installing any software.

In GIMP, the process is typically File → Open for the extracted PNG, then File → Export As and choose a .webp filename. In Photoshop, use a WEBP-capable plugin or export workflow if available. In ImageMagick, batch conversion is convenient when a PKPASS contains multiple images.

Notes on quality, compatibility, or limitations

PKPASS to WEBP is not a true format conversion in the same sense as converting a document to PDF. A PKPASS file contains structured pass data, signatures, and multiple assets, while WEBP stores only a single image. That means the conversion usually captures only one visual component of the pass, not the interactive Wallet functionality.

Some passes include multiple image assets, and the best-looking WEBP may depend on which file you choose. If the pass uses transparency or layered design, make sure your converter preserves alpha transparency. Also note that Apple Wallet passes are often protected by signing and may not be intended for redistribution as images.

For archival or preview purposes, WEBP is efficient and compact. For actual Wallet use, however, you must keep the original .pkpass file, because a WEBP image cannot be imported back into Apple Wallet as a pass.
