Huge file size??

[EWZ]

Hello ,

I am new to Affinity and am just starting to work myself into the programs 

I have created an Affinityphoto file consisting of several cut outs out of JPG's. The file has continued to grow to a size of 1 GB. So I have followed some threads in this forum about file sizes and how to reduce them.

I have tried the the option to delete the snapshot via:
"Save" or "Save as..." the file.
Close the document.
Reopen the document
Then do another "Save" or "Save as..."

This hardly reduced the file size.

Then I have rasterised all the layers and did the "save as procedure again" wich helped a little as it reduced my file to 993MB

Then I took all the layers and copied them into a new file this reduced the size to 928MB

I have then tried to change the format from RGB to ICC wich reduced the size further to 814MB 

But I couldn't find any further advice on reducing file sizes and 853MB is still to big...

 

I have attached my file with the smallest possible size I was able to create and would be very grateful for any advice on how to further reduce the size.

 

Thank you very much in advance

Rasterise & Trim on each layer brought the size down to 6571 kb

Or export as psd, open in Photo, save as afphoto and it's 6446 kb

Thank you very much for your help
I didn't get it quite as small as you did using the same methods but still to a more handball file size of 46,1 MB could you maybe explain why these methods worked so I can understand for the next file.. and skip the trial and error method

or  are there any pre settings, or something I did wrong, to prevent the file from getting so big?

would be great to know

Afraid not, I haven't a clue, Affinity file sizes are a mystery to me. How you didn't achieve the same reduction is the second mystery

When I've finished resizing an image on a layer I find it's best to Rasterise and Trim with the occassional Save AS another name but  that's about it. Good luck

When you rescale a bitmap image, it is not resampled, so it retains all of its original pixels. You can use the "rasterise" command after rescaling, and the image will be resampled to the dpi specified in the document.

That's why some of your layers have a huge dpi (2500+), at 72 dpi of your document.
