Good to know

  • The Photoshop document has a single layer holding the picture.
  • PSB files keep layers; the layers are flattened into one picture, so they are not kept in the PSD.
  • Tick Remove metadata in Options to leave out information stored in the picture, such as the camera and the place.

Frequently asked questions

Is converting PSB to PSD free?

Yes. Everyone gets 25 free credits a day, with no account needed. Conversions on our server use one credit per started minute of work, so most cost a single credit. Credits reset at midnight UTC.

Are my PSB pictures uploaded anywhere?

Pictures up to 200 MB never leave your device: ConvertKitty converts them inside your browser, with ImageMagick compiled to WebAssembly. Only larger files, or formats your browser cannot handle (camera RAW, PostScript, XPS, LibreOffice and Publisher files, and video or audio), are sent to our server, over an encrypted connection, and deleted 72 hours after the conversion. The button says "Upload and convert" whenever that happens.

How large can the PSB file be?

Files up to 200 MB are converted right in your browser. Larger files, up to 1 GB, are converted on our server.

Can I change the size or quality of the PSD?

Yes. Click Options next to the file to set a width and height, choose a quality, remove metadata and more. Only the settings that make sense for PSB to PSD are shown.

Can I convert several PSB files at once?

Yes. Add as many files as you like; they are converted one after another, and each one gets its own Download button.
