I am using Illustrator CC 2019. I have some images which when I open in illustrator, I get the following error. The image is opening fine in MS paint and Picasa photo viewer. I resave the file from ms paint after making few barely visible dots but the issue still persists.

What should I do to fix this issue ?

Correct answer Test Screen Name

Please try this. Copy the file. Rename the file so .jpg is .png instead. Try opening the renamed file.

Rename/change the file extensions: so from (image.jpg to image.png) ant try to open with Ilustrator ore Photoshop 😉

Thanks!!! Your suggestion worked for me. I opened with paint, saved as .png and now opened normally in Illustrator.

There should be no issue opening the JPEG file format in AI, whether you're trying to edit them directly, or trace them is beside the point. AI can open JPEG files natively.

Were these erroring images actually saved as .jpeg from within your photo editing software, or were their extensions changed at the OS level in the hopes of turning some other format to a .jpeg?

If the file extensions weren't just changed at the OS level, it would mean there's some other corruption going on with the file itself. Do they open in Photoshop? If so, you might try clearing the corruption by saving as a different file type, like TIFF or EPS, then opening that new file and saving as jpeg over the original jpeg or possibly just opening the new file type in AI ( it can also open EPS and TIFF natively).

That's cleared the issue for me in the past.

Photoshop doesn't open the file as well. This is really unusual as a free software like ms paint is able to open the file but not photoshop and illustrator.

I get following error in photoshop.

I did not change the file's extension. It was saved as jpeg only from the beginning.

You might be able to save as a different file type in one of your other programs to get past that error.

There's definitely something wrong with the files themselves if neither AI or PS will open them.

arjun,

In addition to what Steve said, you can have Link ticked for a linked file or unticked for an embedded one.

A linked file helps you keep the AI file size down since it is only referred to, an embedded file adds to the file size but allows you to change the (appearance of the) image in certain ways such as the Object>Envelope Distort options and the Effect>Warp options.

Illustrator creates vector objects, not pixel-based like MS Paint or Picasa.

You DON'T OPEN a JPEG file because it is composed of pixels.

If you'd like the JPEG image to appear in your illustration, you choose File > Place and scale to the size you like. But you won't be able to edit the JPEG file.

I was using it as a drag-n-drop reference linked file only.

When I chose place, I got the following error.
