I'm copy from Photoshop CS6 this selection:

enter image description here

Which is exactly 16x50 pixels, correctly snapped with grid.

Once I paste in Illustrator CC 2019, it round both pixel sizes and grid position:

enter image description here

Why 15,998x49,994px at 121,999, 144,997 position?

Can I keep original pixels and preserve sizes?

Or do I need to manually fix it?

    Hi. Welcome to GDSE. It's only a rounding error. You can ignore it. There's nothing to fix. Also why didn't you just create the image in Illustrator? There's no need to use Photosohop at all for this. – Billy Kerr Jun 8 at 9:54

I think it's default behaviour

The only possible reason as i think must be again photoshop pixel characteristic vs illustrators vector characteristic.

so the steps i followed was changing dpi and images etc and i figured out that whenever you embed physical file it always embedded with scaling of 100% while same file opened in photoshop and when pasted it into illustrator it embedded with scaling of 99.987% . i tested same with low pixel resolutions like 4*4 px etc and it's also embedded with 99.987% but the display will show complete 4*4 instead of some float value so below is my conclusion

From my perspective : this can't be changed since it must be algorithm issue of illustrator which embed images from clipboard and there might not be any other solution.

the only logical solution is make your dpi something which converts 99.987 ratio to 100% and that dpi is exact 72.0093612 and when i made my canvas to 72.0093612 dpi and then exported the magical thing was shocking since if photoshop really converted it to float DPI then illustrator image should be embedded with 100% instead of again 99.987 so basically you have no chances other than resizing manually.

figure 1 : embedding physical file

figure 2 : embedding clipboard file

enter image description here

figure 3 : values while embedding @99.987% exact in low resolution float in high

TLDR : Don't worry about placed files since it's very low different and it can be overrided easily but if you talking about changing default then sorry it shouldn't be possible as far as i know

    It seems Photoshop use ppi as integer and illustrator as float? Thats the rounding error... – markzzz Jun 8 at 7:11
  • yeah that might be point. anyway but sorry for your problem since that's all I can help :) even we all face same. it jus't maybe i didn't noticed it at all since always i do scaling manually :P – Mr.Online Jun 8 at 7:18

Verify the psd document has exactly 72 ppi as resolution

enter image description here

If that's the case, there shouldn't be any problem:

  • Yes, it has 72 of course – markzzz Jun 7 at 19:53
  • @Danielillo I think we can't change this property since it is some core level issue :) – Mr.Online Jun 8 at 5:28

I'm not sure changing PPI would matter. But it's strange, it's almost like you are working in... megapixels??? Test it out on blank documents and try again, if it's still giving you issues reinstall. I just had a bug last week where my illustrator snap to pixel grid worked fine, but the visual lines themselves were rotated 1 degree counterclockwise. nothing like a fresh clean install to keep me from ripping out my hair that I don't have :)
