Project with pixel layers become huge suddenly

my project is 3000x2000 points and has over 200 vectors and several reference images in that, the project file was always about 20 mb.

I then decided to add some textures and grain so I switched to the pixel persona (I’m new to that) and add about 10 pixel layer where I used several different brushes.

The project file suddenly reached 500mb which is a lot to save and backup on cloud drives. 
how is that possible? Few pixel layer can make such difference? Is there a way to downsize them since they contains only grain and light textures, no real details? What is the best approach with pixel layers to avoid that?

thank you very much!

Hi Ste72,

How did you import the textures did you place them into your documents as JPGs using File > Place.

Thanks

Hi, no sorry, I didn’t explain well, I’m a beginner... I wanted to get a sense of texture so I just add pixel layers and draw on them with different brushes, very slightly... so overall I have 10 different pixel layers each of them is masked inside a vector layer. 
how can this make the project so huge? Is there a way to tell Affinity to compress those pixel layer when storing them in the project? I do not need the details in those layer,  I just put there some grains to mimic some rumor and a bit of texture.

thanks!

I understood where the problem was by removing one pixel layer at the time and checking the size each time. There was one pixel player that required 350mb to be stored, on that I used a brush that I bought and imported in AD (not one provided by Affinity), I just used it to add some grain so that’s quite surprising for me... anyway I guess the lesson here (at least for me) is to pay attention at which brush I’m using to avoid such behaviour.
