Illustrator changes the image resolution on its own when placing it

[Guest]

Illustrator changes the image resolution on its own when placing it , but not all the images !!

I placed an image  with 300 ppi into illustrator and it changed to 72 ppi, that of course changed the size significantly.

P.S. - I used place command in file menu, i dragged the image directly to illustrator and used the open command in file menu, same result
- I checked the page resolution and the document raster effects, they both 300
- I tried another vector software it didn't change the image resolution.

- I saved it as TIFF from photoshop (which read the size and resolution correctly) and illustrator got it right !! but i need it jpg !!

So, what could be the problem here ??

"5 Same JPEG re-placed when cut and pasted into new document 300dpi at 100% - CORRECT SIZE AND SCALE"

Does that mean that Photoshop did not save the ppi correctly the first time?

It did save it correctly, I have been told by Adobe that there is a fix in V.23

Hello, I have the same issue. Adobe, please could you fix it? If the image you've pasted has the resolution other than 72 ppi, Illustrator changes its size. Leave the size of the image - it is more important than ppi.

"Hello, I have the same issue"

Since you have a different version, can you please create a new thread?

And post step by step what exactly you are doing?

Also image specs and what exactly happens. Thank you.

Sure, here it is

In the View, click "Actual size" and it should fix it (you can also press Ctrl/Cmmnd + 1)

People should learn that PPI's says nothing about resoultion. 

It's just information for a printer or output device.

If you take a 1000px x 1000px in photoshop, you can put it on 72ppi/dpi. The printer will print 1000/72 =13,8 inch wide/high. If you change the image to 300dpi (without checking 'RESIZE IMAGE') the resolution will still be 1000px X 1000px but the printer will print it at 1000/300 = 3,3 inches wide/hight!  So much misunderstading about dpi/ppi.  Just focus on RESOLUTION in pixels when you are working with pixels!

If you open the original file in illustrator and copy it to your desired illustrator file, the resize doesn't applied to the picture

It's 2022 and I've been wrestling with the same issue as everyone else in this thread. For the record, I'm an experienced CC user and am using the latest edition. After messing around with this for hours....here's how I solved the problem:

1. I resized my image in Photoshop to the exact size needed in my Illustrator document and saved as a PSD (my photoshop document settings were 300 ppi, CMYK color, and US Web Coated (SWOP) v2).
2. In Illustrator, I used "place" (Shift+Ctrl+P) to place the psd image. (My Illustrator settings were CMYK and raster effects High 300 ppi. And my View was set to Overprint Preview.)
3. Clicked Embed
4. Then right clicked on the image and selected "Make Pixel Perfect"

The jagged edges of my image finally disapeared and became sharp. And remained that way even when viewed at 400%. Good luck!

I got the same problem. But I later I found out that instead of open or place the image, I simple drag down from the downloaded folder, The pixel size of the image does not changed a bit. I realized it very late but helped me a lot when i had to image trace them. Hope this is helpful to anyone who reads.

For some genius reason, illustrator seems to use the physical image dimensions/dpi which you can set in photoshop rather than using the pixel dimensions like every other program on the planet. This worked for me: 

1. Open it in photoshop
2. Image->Image Size
3. UNCHECK "resample" so photoshop will not change the pixels, it will only change the DPI/Size. So let's say you have a 1000px by 1000px image which photoshop has set to a 4" x 4" physical size at 250 DPI, and you change the image size in photoshop to 8"x8"... with resample checked, you'll have a 2000x2000 image at 250 dpi. With resample unchecked, you will have the same exact 1000x1000 image, but it will set the dpi to 125.
4. Import the image with the new physical dimensions/dpi into illustrator and it will set fine.

Illustrator will honor the ppi settings from Photoshop. If you change it in Photoshop without resampling, you will keep the same number of pixels, but just change the metatada that tells Illustrator how to set the size when you place it.
