One of our most highly requested features, the ability to upload a ZIP archive, is now live. Many users will find uploading a ZIP through our Web Interface to be far more productive than optimizing images a one-file-at-a-time – of course, if you prefer, you can still drop in as many “single files” as you like in one go.
Being able to upload a ZIP to get the contained images optimized presents several advantages:
- The folder structure within the archive is preserved, so you won’t need to reorganise your data, which can be quite tedious. For instance, WordPress users might like to ZIP the contents of their wp-content/uploads folder, let Kraken.io optimize them, and then overwrite the original folder on their WordPress blog.
- The approach we have taken is that once the ZIP archive has been fully uploaded, Kraken.io will fire up a background job to do the busy work of unpacking, optimizing and re-assembling the archive, meaning you can safely close your browser (or laptop) and come back later. Once the job has completed, the “optimized” ZIP archive will be available for download in the Optimized Archives section of your Kraken.io account, where it shall remain for as long as you need it.
How do I use this feature?
To use the ZIP uploader, simply visit Web Interface PRO while logged in to your Kraken.io account. You’ll notice a new button below the dropspace labeled “Upload a ZIP Containing Your Images”. Clicking on it will present you with a dialog box inviting you to select the ZIP you would like to upload from your computer.
Before you do that, you might want to tweak the optimization settings, located at the top section of the uploader, to your preferences. Any and all settings you choose will be applied, as with the normal Uploader tool.
Once you have selected the archive you would like to have optimized, you will get an upload progress indicator until the upload has completed. It is important that your browser remains open during the upload process, but once it is done, it is safe to close your browser. You can come back later to download the optimized archive, as previously mentioned.
The archive will remain in the Optimized Archives section of your Kraken.io account until you decide to delete it.
What happens to other (non-image) files present in the original ZIP archive?
You’ll get those back too. The archive will be the same as it was before, only with less bloated and faster, better images.
That’s it! Feel free to drop us a comment or an email us if you have any questions about this feature, we would love to get your feedback!
