Version 2.0 of PixCompare for iOS available


PixCompare V2.0 is a major rewrite of PixCompare – focusing on cleaner and easier useability. There is basically just one button that you have to press to initiate search and use the app.

With the release, we also decided to change the business modell of PixCompare. Instead of a free download with an in-app purchase, we are now charging $0.99 right from the start.

Updates for PixVeew and PixCompare Mac posted

New versions for both PixCompare Mac and PixVeew are available.

PixCompare for Mac Version 4.2

  • Increased limit for one-to-folder search to 100.000 pictures
  • French localization
  • Up/Down keys also work when main window is not in front

New Version of PixCompare and PixVeew

Both applications were updated, among other things, support for 10.11 (El Capitan) was improved. See PixCompare and PixVeew on lakehorn.com.

For PixVeew, I’ve decided to remove the “Plus Mode” In-App purchase. In the 6 months I’ve had this feature, about 60 users actually payed for this upgrade.  This does not add up for me. The additional effort is not worth the earnings in any way. Therefore, I’ve removed the In-App purchase and activated all features in the basic mode, i.e. unlimited printing and recompressing.

I want to sincerely thank the 60 people who chose to pay for the “Plus Mode”. You still made a difference! Together with the 4000+ users, this justifies the continuation of the development of PixVeew. New features and versions will be available in the future. If you have any specific request or idea, contact me!

Update to PixCompare

New version V4.1(.1) was posted today to the Mac App Store. Update includes:

  • Improved performance on the comparison part of more than 2x
  • Therefore increased limit of number of pictures to 30.000 – on a fast machine it takes about 15 minutes to compare that. (depending on the picture size)
  • Added Finder server so that you can start a compare of a folder directly from within the Finder
  • some bug fixes and improvements to the compare algorithm

Let me know what you think or contact me for improvements or ideas!

Updates for PixCompare and PixVeew posted to Mac App Store

Version 4.01 of PixCompare improves comparison performance by more than 2x. Also updated the minimal requirements to Mac OS X 10.8.

Version 1.1 of PixVeew (new name, changed due to already a lot of PixViewer apps floating around). Added some controls in full screen view that were available in the old FastPic. I’ll add more feature from the old apps, but they will be available as an in-app purchase only.


PixCompare 4.0 now available on the Mac AppStore!


Using PixCompare, you can compare picture files to search for duplicates or similar pictures in a large collection of picture files. It works on JPEG, PNG and GIF files.


I finally finished the Cocoa update for PixCompare! This was a complete rewrite, so that current and future Mac OS releases will be supported properly. Starting with this version, I’m also going to charge a small fee for the application. I plan to add new features over the next couple of months, including the now missing printing functionality. If you have any ideas or feature requests, contact me!

PixCompare Terminal command

The is the first release of the PixCompare engine for command line use. It takes 2 jpeg files and returns a similarity value.

I have several Axis webcams in use, and sometimes their built-in motion recognition just runs amok – it saves a picture every second even though there is no motion at all. Therefore, before copying the pictures away, I use this command to compare the current picture with the last picture taken. If it is different enough, it gets saved.

Download pixo_cmd

% pixo_cmd picture1.jpg picture2.jpg

It returns a float value 0 or higher, where

  • 0.00 – 2.00 very similar or identical
  • 2.00 – 10.00 pretty similar
  • 10.00 – 20.00 somewhat similar, e.g. some colors are the same
  • > 20.00 different
