@Aaa Bbb - You can drag-and-drop multiple images from your desktop onto a Miro board via a browser or Miro desktop app.

But I use only iPad

But you said "but can I do the same using website", so I assumed you were asking of you could do this using a browser.

Yes, browser on iPad

@Aaa Bbb - My second reply was sent at 4am while sleep-deprived due to our first baby who is 5 weeks old 

Let’s take a step back and put this all together into one question:

“Can I select and upload more than one image at a time using a browser on an iPad”?

My answer: I don’t know what is possible on a browser on an iPad, however, I can say that it works on a browser on Windows 11:

Next, I tried this using the Chrome mobile browser on my Samsung Android 11 phone, and I chose to put Chrome in “Desktop site” mode, and I could select images and upload them to a board at the same time:

You could try this using Chrome on your iPad.

2025 August Entry - I found a way to upload many images at once. Drag and drop of multiple image into the MIRO canvas (using windows) is not permitted

Step 1: Load them into a cloud storage folder ( I am using Microsoft One Drive)
Step 2: Use the upload feature in MIRO (where you can select the cloud drives)
Step 3: Select all the images and click upload. All your images will be upload as a batch

Tip: Once all images are into Miro, select all the images. At the top right - there should be a round circle with 4 white circles within. This should be the auto layout handle. Drag to the right or drag down. Miro will help you arrange the images in a grid (especially if your images are powerpoint slide images). Hope this helps some one
