Round to Pixel command
XD could really use a Round to Pixel command. Yes, I'm pulling this straight from Sketch, but it's awfully useful. The command simply rounds every anchor point to the nearest whole-pixel value, eliminating fractional pixels.
This feature has been added in our November update (version 0.6.2): choose Object > Align to Pixel Grid to tweak the X/Y/W/H so the object(s) are crisply aligned with the pixel grid. You can use this command with a multiple selection or with groups selected to align multiple objects at once.
Note: aligning to pixel grid does not always mean the X/Y/W/H won’t have fractions. For center-stroked shapes (lines and Pen tool, mostly), sometimes the X/Y need to end in .5 to keep the stroke crisply aligned on-pixel.
I see some people in the discussion thread here are asking for snap to pixel “by default.” Adobe XD should already do that, with very few exceptions (see https://adobexd.uservoice.com/forums/353010/suggestions/16962847-resizing-multiple-selection-or-group-loses-pixel-alignment). If you’re encountering other situations where objects you created in XD are not pixel aligned by default, please file a new bug here in UserVoice.
Thanks everyone for all your feedback and votes on this feature!

You create an element at 56x56px, but then you move it around and the spacing between elements then has decimals. When all you just want it to snap to grid.

XD on Windows doesn't have the top level menu, so I can't choose the option "Object>Align to Pixel Grid"...
Is there a keyboard shortcut ?
Snap to pixel by default would be way better. Never in my puff have i specified a box to be 212.5 x 214.3px with a margin of 22.5px all around. :/
If you're building an app for Web/App UI it should be restricted as such.
PS Blend modes please
I don't understand why we need subpixels!!! they are so annoying.
I get decimal values constantly. They are rarely perfect .5 values either. I find myself wandering through my prototypes looking for them and removing them manually.

Yeah, If we can we have a keyboard shortcut for that, that will be epic
RE: "Note: aligning to pixel grid does not always mean the X/Y/W/H won’t have fractions. For center-stroked shapes (lines and Pen tool, mostly), sometimes the X/Y need to end in .5 to keep the stroke crisply aligned on-pixel."
Can someone please explain to me why this happens? I find the .5 values to be a nuisance when aligning and measuring distances between elements.
I'm assuming this has something to do with the line being centered over the pixel, but I'm not sure I fully understand. If I were to create a 1px tall rectangle instead, I feel that it behaves more like how the line SHOULD behave. Am I missing something?
Snap to pixel by default not by command please Tom.

This is a constant irritation. Please snap to pixels by default when resizing objects. The measure feature doesn't work when objects don't snap to pixels.
example: A box is 100 x 100px on the 100x 100y. Drag another box to position it but the second box is 100.53x 100.52y these items will not "align" properly.

In addition, resizing things like boxes breaks objects from the current rounding into fractional pixels at times.
Isaac Powell commented
Yes, make align to pixel the default for all, with object-level override available.
I agree with the comments below. Snap to pixel should be default and other pixel options can be tweaked as and when desired. Glad to see this started.
Having to mess with fractional positioning in the input field when resizing or positioning when there could be an option to be all be aligned to pixel grid would be great.
Note: XD should keep most of your content automatically snapped to the pixel grid by default. The main case it doesn't is when creating paths with the Pen tool.
If you're seeing other examples where content you created in XD is not crisply aligned to pixels, please let us know by creating a bug report at https://adobexd.uservoice.com/forums/353010-adobe-xd-bugs.

This is a big one for me. Today, I was trying to create an icon with widths that where 1.5px (or 3px @2x) and it was a real pain to have to manually add '.5' to my dimensions in the attributes panel.
Who is using sub-pixels? Seriously. Round to Pixel should be by default not an option.
Alan Valek commented
Daniel, elements still render better if designed on a pixel grid.
It seems like XD is snapping to grid by default? Everything should snap to pixel grid by default and you should tell it that you want a specific element to go sub-pixel.
