[Jpeg resave much bigger than the original]

Thank you all for your answers!

- But I still don't understand why the file is 3 times bigger than the original. You can all just try it by yourselves.

Because if I want to keep the same weight than the original, I should export it at 60% quality, and the result is awful...

- And I don't understand why, when I do a 2nd export (from the 1st one), the weight doesn't change much.

Thank you Carl and Walt for the replies!

When I resave I use File > Export, and I keep 100% quality. But I think that 3 times bigger than the original size is weird, no?

You can do the test by yourselves with small files around 200Ko-400Ko.

Hi there,

When I download a jpeg picture from the internet at 200Ko for example, if I resave it in Affinity v2 , it grows to 600ko. So 3 times bigger!

But if I resave the last one, it grows from 600Ko to 620ko.

It is usually better with webp files.

Why is that and how to avoid it?

Thanks.
