It could also be nice with an loader indicator after pressing add, people will think they haven't pressed the button...

Could you please provide a test case? This may depend on the exact accept attribute value, as one theory that comes to mind is format conversion taking the time. Also, what are the camera settings in both cases, are the photos JPEG or HEIC? 1945005 4 jesperbendtsen83 2023-03-29 09:13:46 -0700 I can give you access to the test system, actually you already have access with safaribrowsertest@hotmail.com from another bug report? I can guide you guys to the upload area, if its okay?

Please help my users are complaining... 1956927 8 jesperbendtsen83 2023-05-22 05:45:16 -0700 The same thing happens in iOS 16.5 In iOS 16.3.1 adding 60 images in a file input takes about one second, in iOS 16.4 and above the same thing takes over a minute!? Public test site, scroll to "Using file inputs", add about 60 images: https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/file#using_file_inputs 1957434 9 georaldc 2023-05-23 14:08:03 -0700 (In reply to Jesper Bendtsen from comment #8) > The same thing happens in iOS 16.5 > > In iOS 16.3.1 adding 60 images in a file input takes about one second, in > iOS 16.4 and above the same thing takes over a minute!? > > Public test site, scroll to "Using file inputs", add about 60 images: > https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/ > file#using_file_inputs Been noticing this same behavior as well where there is a delay after selecting multiple images that seems to grow the more images you select. Just curious, but have you also been experiencing this issue I brought up here? https://bugs.webkit.org/show_bug.cgi?id=256711 Ever since 16.4.1, our users have been randomly encountering this issue now. Just happened to see your bug post as I was searching for other closely related issues (that dealt with browser uploads on IOS 16.4 and newer) 1957665 10 akeerthi 2023-05-24 11:21:06 -0700 (In reply to Jesper Bendtsen from comment #7) > Any update on this? Please help my users are complaining... Apologies for the late response. This is something we are looking into. The issue is fallout from our adoption of a new system photo picker in iOS 16.4. However, we have identified ways that we can improve the performance in WebKit. 1978374 11 jesperbendtsen83 2023-09-19 11:57:27 -0700 Still extremely slow in iOS 17, any update? 1978709 12 akeerthi 2023-09-20 10:22:17 -0700 After additional investigation, it appears that this issue is underneath WebKit. I don't have any other updates at this time. 1979900 13 ap 2023-09-25 12:07:12 -0700 Let's mark this as RESOLVED/MOVED for clarity. Please file any additional reports via https://feedbackassistant.apple.com for Apple engineers looking into this to have the most visibility into your feedback. 2005632 14 jesperbendtsen83 2024-01-17 11:29:09 -0800 Are there any plans to make this better? We have a web app where our users often take 60-70 photos for upload. It takes approx. one minute before they return to the web app after selecting images from the iOS image gallery and uploading can begin. Users think iOS has crashed, no loader is shown. Can't you go back to the old photo API before iOS 16.4, back then it was fast, there was no delay after selecting 60-70 and the upload started immediately in iOS Safari. Why is it so super slow now in iOS Safari, please explain? Doesn't feel production ready...
