Is there a way to make readable text in jpg using only 20% quality?

Hello Guys, 

 

I work with maps and delivery system.

So, the map layer is in 20% quality jpg, and that's nice.

 

But if I create a layer of text and instructions, and save the image at 20%, the text will be not good to read.

So, I need at least 80% to make the text nice, but the final file will be too large and the map will be same.

 

Is there to save the image at 20% and make the text readable? (I create white boxes with black text inside).

 

Greetings from BR.

20% quality for a JPEG is pretty much garbage level quality. I don't think you'll be able to get what you want.

 

You can also experiment with the Chroma Subsampling options in the Save Configuration dialog. There's only 3 settings and their description makes it clear which ones are best quality vs. smallest size. 4:4:4 is the best, 4:2:0 is the worst.

Dumb question but feel like it needs to be asked. Why are you using JPG?  It erode over time since it is a lossy format.  Have you tried saving in PNG instead?

It's because the images are used on phones, so it need to open fast. 

I think PNG is a little slow to open.

 

I tried 50% and it's readable now. Thanks.
