macOS - Bulk convert Photoshop PSD files to PNG

Hans — Tue, 20 Jan 2026 08:38:24 +0000

I had to convert quite a few simple PSD files to PNG files (this trick may not work with very complex PSD files).

What worked very well for me:

Rename all PSD files for PNG (so mypic1.psd -> mypic1.png, mypic2.psd -> mypic2.png, etc).
In Terminal, in the directory where the renamed PSD files are store:
```
sips -s format png *
```

This will convert all images (*) to the png format, pretty quick. Note that each file will be overwritten by its PNG formatted version.

I did use HexFiend to verify the headers and make sure these are now indeed PNG.
To optimize the images (saved app. 40% in filesize for my files), use: ImageOptim (highly recommended to optimize file size for PNG and JPG images).

Note: sips (Scriptable Image Processing System) comes with macOS (seemingly since 2005).

Photoshop - For free and online with PhotoPea

For those hating the subscription model of Adobe (like myself) and that are stuck with a broken (old) Photoshop, consider checking out PhotoPea.

It looks, feels and works like Photoshop, it even support layers, effects, actions, transforming with perspective, etc ... it all works!

Since I only every now and then work on graphics (and previously used Photoshop, as I have been using it since version 1), this has become my go-to graphics editor. It runs in your browser, and once the page has been loaded you can even disconnect your Internet connection and keep working. All in your browser.

Truly amazing how they managed to do this and I highly recommend it.

PhotoShop - How to hide multiple layers at once

Hans — Thu, 25 Jul 2013 11:19:04 +0000

I've been using an awesome little screenshot tool for the Mac that takes a screenshot to a PSD file with all desktop items in layers. The downside is that I typically have a lot of stuff going on when taking a screenshot, so it produces a lot of layers.

The easiest way to hide multiple layers at one is easier than I thought it would be:

Select All the layers you'd like to hide.
Right click (or CTRL + left click) the little eye in front of one of the layers.
Click "Hide this layer".

This will hide all the selected layers - see also the attached screenshot.
