Can it support images of size in 4-5 GBs?

Can I upload & edit a large image of size varying in GBs? Also will I be able to zoom in & zoom out to that image to the pixel level?

• There are total memory limit on browser tab (16G limit per tab in Chrome, but 32GB on Firefox ?).
• There image dimensions limits, that browser can handle.
• Even PhotoShop has limits: "PSD limits pixel dimensions to 30,000 x 30,000 and max size to 2GB (but not PSB format, which can handle 300,000 x 300,000 and 4 exabytes).

miniPaint does not check any limits, but undo feature will not work if you load too much data. I tested minipaint with 150 MB JPG image, it works, but slowly.

I am almost sure that if you load few GB image, it will crash because of exceeding limits or will take lots of time to load on computer with lots of memory. You can always try and let us know. But I personally would try to use desktop apps to edit such big images.

And it is nothing can be done to optimize even more, because miniPaint is already optimized to save memory as much as possible.

Thanks for the inputs.

Hi, Today I tried opening a 40 MB photo on minipaint. But it gave me error. You had mentioned that you were able to open a 150 MB photo (though it was slow). So I was curious to know how you managed to open the same? Any setting that we need to take care of? Please let me know. Thanks.

Can you share that image? I image if it is few colors PNG with very big dimensions, miniPaint could have problems. OR maybe wrong format? it should open 40 MB images without big issues.

p.s. there are no settings for that, default miniPaint must open such files.

You can try this file: https://effigis.com/wp-content/themes/effigis_2014/img/GeoEye_GeoEye1_50cm_8bit_RGB_DRA_Mining_2009FEB14_8bits_sub_r_15.jpg It does not works both ways, either by specifying URL or by downloading & specifying its local path.

I can open and edit it.

But it gave me error

What errors? how you are opening it? And which browser & version?

Here is the screenshot of error. I'm using option File -> Open -> Open URL & giving the URL https://effigis.com/wp-content/themes/effigis_2014/img/GeoEye_GeoEye1_50cm_8bit_RGB_DRA_Mining_2009FEB14_8bits_sub_r_15.jpg in there.

You get CORS (https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS) error, basically effigis.com server does not allow to take resources from its domain using JavaScript. You should save that image on your computer and open it locally.
