With Slidebank being a web application, there are some natural file size limits, above which the server is likely to time out on upload.
The limit for individual file uploads is currently 250MB.
This issue is not as straightforward as it may seem, however, since it's a question of server load. A very large but uncomplicated file may actually cause less of a load on the servers than a smaller file with more intricate setup.
Now that more people are working from home, there may also be home internet bandwidth issues at play.
If you are finding that your files are timing out on upload, please:
Check the file size. Is it over 250MB? If so, it may need to be broken up into different files or made smaller in some way (see below) before uploading.
If under 250MB, please cancel the upload and try again. There may have been an issue with internet connectivity interfering with the upload.
If the problem persists, please get in touch and we'll investigate.
How can I make my Slides smaller...
Whilst most PowerPoint slides weigh in a just a few kB each. However, we occasionally come across excessively large slides of 10MB each, and it doesn't take many of them to make a PowerPoint file exceeding 250MB.
Here are some things you can try to reduce side sizes:
First off, you can get PowerPoint 2019 itself to compress the slide images.
Click ‘Save As’ and ‘Tools’...
...then experiment with the PowerPoint compression options shown here…
Secondly, there is a useful piece of software called NXpowerLite, (https://www.neuxpower.com/nxpowerlite-desktop) which claims to reduce the size of PowerPoint and other Office files by up to 95%. A 14-day free Trial is often available, so you might want to give it a go.
Lastly, an unfortunate habit of some creative Agencies is to simply drag and drop huge graphics (often TIFF files) straight into your slides, resulting in images that would project well onto the Empire State Building but which are overkill for normal use. This is often done to save an Agency some time, so just ask them to stop. What they should really do is reduce excessive graphic files to a size altogether more manageable - especially helpful for cloud-based Apps.
