Kindle Collection Manager

by

I wrote the Kindle Collection Manager many years ago to add missing functionality to the Amazon Kindle range of eBook readers.

It’s a Windows desktop app that allows books to be arranged into collections – both manually and automatically based on folders – then the collection configuration is uploaded to the Kindle device.

Unfortunately Amazon locked down the file system on all devices from the Paperwhite onward which renders the app unusable.

For owners of previous versions of the Kindle eBook reader where the collections.json file is still accessible over USB, the KCM will still work.

Here’s a link to download the last version that was released.

Lossless compression of JPEG, PNG, GIF, TIFF and BMP images

by

After years of using the JPEG & PNG Stripper to remove the metadata from my images before publishing on the web, I’ve recently discovered an even better tool.

It’s called PNG Gauntlet and performs LOSSLESS compression on JPEG, PNG, GIF, TIFF and BMP files.

It analyses an image file, strips any redundant information and metadata then applies multiple compression methods until the best result is found.

In my experience, it can even reduce the file size of images that the JPEG & PNG Stripper has previously processed.
