Convert Sketch to PSD
Sometimes, we want to work with Sketch graphics in Photoshop. Sketch does not provide a PSD export, and Photoshop does not provide a Sketch import. Converting it manually is hard, but it can be done automatically, see how!
Sketch to PSD
Today (the beginning of 2020), Photopea is the best tool to convert Sketch graphics to Photoshop files. Go to Photopea.com to start a free online photo editor. If you see a Welcome Screen, you can close it by pressing the Cross in the top right corner.
Open a Sketch file from your computer: click File - Open (in the top left corner), then, find and select the Sketch file (or use drag and drop).
You should see the graphics of the Sketch file in front of you. Now, just click File - Save As PSD. And that's all! So simple :)
Missing fonts
If you see the text rendered with incorrect fonts, you can load the correct fonts into Photopea before opening a Sketch file (File - Open, choosing one or more TTF / OTF files).
Photopea can let you store these fonts in a Local Storage (so that they remain even after closing Photopea). The Local Storage can be cleared in Edit - Local Storage, or by deleting cookies and site data in the settings of your browser.
