Due to limitations in the iOS/iPadOS web browser, on iPads Repper cannot export from source images that are either wider or taller than 4,000 pixels.
You can still design patterns from such source images, but you'll need to export the patterns from another device, like a desktop or laptop computer.
Like your exports, snapshots for patterns based on source images larger than 4,000 pixels in width or height will also show up blank (but rest assured the pattern is still saved; just click a blank snapshot to see the editor load the saved pattern).
<aside> 💡 An easy way to save your designs on iPad and export elsewhere, is to save them as snapshots. Snapshots from too large source images will show a broken icon on iPad, but don't worry, they will work fine on other devices.

Repper is capable of generating large exports on iPads, but it will depend on the age and capabilities of the specific iPad model you have. Older models have less memory and thereby may performance slower or fail to export large patterns, while newer models are very performant.
Due to iOS limitations, the quality of the image will effectively be limited to a 2 megapixel image. Even if you set it to for example 4000×4000 pixels, iOS will downside the quality of your image down to 2 megapixels.
What does this mean for you? If you want to export your pattern larger than 2 megapixels (for example, larger than 2000×1000 or 1400×1400 pixels), do it on another device than your iPad.
If you go over this limit on an iPad, we will give you a warning, so you know what's happening.
<aside> 🍎 Note that this limitation has nothing to do with Repper specifically. Any image you download from a browser on iPad will be downsampled by iOS.

We’ve tested on the latest version of iPadOS (17) and it seems this limitation is no longer there. We need to do more thorough testing, but we can confirm that the limit is now substantially higher than 2 megapixels.
