How do I convert PSB to JPG?

Upload your PSB file above. It is converted to JPG automatically (change the output format or quality in the Settings tab if you need to), then click Download. There is nothing to install.

Does converting PSB to JPG lose quality?

JPG is lossy, so some fine detail is discarded to make the file smaller. Raise the quality in Settings for a closer copy.

Will the JPG keep the transparent background?

No. JPG can’t store transparency, so transparent areas are filled with the background colour you pick in Settings (white by default).

PSB or JPG: which should I use?

Use PSB for huge Photoshop projects larger than a PSD allows. Use JPG for photos you share, email, print or upload. Keep in mind the main drawback of JPG: no transparency, and every re-save loses a little more detail.

PSB is Photoshop’s large-document format for files bigger than 2 GB or wider than 30,000 pixels, such as panoramas and large-format print designs.
