Gimp file exported as .jpg no longer compatible with Canva

[TheArtOfAdventure]

I have used GIMP for years and saved my art as jpg's and then succesfully uploaded them to Canva for printing.  I got a new laptop and installed the new GIMP and now when i export as a jpg it works, but when i export it to Canva the files say "We are unable to upload this file as it is incompatible with Canva or it has been corrupted".  
My old jpg files i saved on the previous computer still work to upload no problem.  I have double checked that Gimp is still exporting as an RGB format, and have tried all sorts of other stuff to no avail.  The exported files are definately a .jpg but they are no longer recognized in Canva as compatible.  I have also updated my browser as well.  Does anyone have any ideas on how to get this to work?  I work with Canva all day long and now can't upload any of my files, I have no idea how to fix this.  
I wonder if i should download the older version of GIMP, since it still works on my old laptop but not the new version on my new laptop.  What could have changed?

Not much help on the Canva jpeg requirements page, so best guess.

A jpeg can be progressive or interlaced. By default Gimp 2.10 jpeg is progressive. Try re-saving with progressive un-ticked in the export advanced options. While there maybe un-tick all the metadata options as well.

Thank you for your quick reply! Your right, Canva isn't much help with thier requirements. I have gone ahead and done that, and have attempted to upload in Canva but it has the same incompatibility issues. I tried a bunch of different combinations, but especially unticking the Progressive in the export advanced options. I wonder what could have possibly changed in the updated Canva so that jpg's are no longer compatible? I have been digging more into the actual jpg files and they look the absolute same in properties. Am i able to find a copy of the older GIMP and download it on my new laptop? I need to find a solution, even if its a workaround since this is what i do for a living and i use Gimp and Canva everyday. Any other outside the box ideas anyone has? Thanks in advance for your time!

Are you really using Windows XP ? Not that it is a problem.

What version of Gimp were you using and I will get you a download link. Otherwise you have to go here: https://download.gimp.org/mirror/pub/gimp/ and trawl through the various versions.

One snag is installing an old version will / might uninstall your Gimp 2.10 It would be better to determine what is wrong with the newer images

If you have an old (workable with Canva) image you can share, then there are tools such as command line ImageMagick which can determine the file properties.

Edit: Just a thought. What determines your image size? Gimp 2.10 now defaults to 300 ppi (used to be 72) so if you set canvas size by inches the file size is that much larger.

I do believe I have Windows 10.

I was using Gimp 2.10.8 on my old laptop, and have Gimp 2.10.14 on the new one. I would love a download link!

If i can solve the problem with the newer images I would definitely prefer that, but I have no idea how to fix that so going back to an old version might have to work.

I'm not sure what you meant by "If you have an old (workable with Canva) image you can share, then there are tools such as command line ImageMagick which can determine the file properties." I am not familiar with ImageMagick and what it does. Can I attach a jpg image thats compatible with Canva and one thats not on this forum?

File sizes shouldn't be an issue with the new default 300 ppi. I work with 600mb files and then save them as a jpg at a much saller size. Canva limits their file sizes to 25mb but mine is always well within that.

I will be surprised if there is any difference between a Gimp 2.10.8 jpeg and Gimp 2.10.14 however:

The last Gimp 2.10.8 installer to download
https://download.gimp.org/mirror/pub/gim...etup-2.exe

comes from here: https://download.gimp.org/mirror/pub/gim...0/windows/

I did see the Canva file sizes and limits but worth asking the question. They also take png format.

Thanks so much for your input! 
After working with it and experimenting for the last few hours I have discovered its NOT the different version of GIMP.  I took the Tiff. file to the old laptop and saved it as a .JPG in GIMP and the same Canva problem occured. 

It seems the problem is the original .Tiff files that I scanned of my artwork.  The old ones i scanned pre-December work great and export as .JPG's and upload to Canva no problem.  The new ones that I scanned in December don't work, no matter how many i try.  The ONLY difference is that i changed the DPI scanning from 360 to 300. (and I made the dimensions bigger which made the file size bigger from 300MB to 600MB but that shouldn't make a difference because when i convert it to JPG i compress it to a smaller file size.)  

Do you have any thoughts on how a scanned .Tiff file opened in GIMP and exported as JPG is now no longer being recognized as compatible in Canva from December on? It just seems SO weird, how could a converted .Tiff to JPG no longer work?  I can succesfully save the older .Tiffs (pre-December) in GIMP and they upload to Canva just fine.  Very mysterious? :-)

Beyond "progressive" there are now two rather different version of JPEG, the JFIF format and the EXIF one. JFIF is the "traditional" one, EXIF is a bit more recent and more complete (can also include sound...). AFAIK Gimp produces the JFIF, bt this could be a matter of library used.

The format is reporded by ImageMagick's identify -verbose.

Just some thoughts and long shots.

Scanned tiff's from old laptop work, tiff's scanned in new laptop fail. What changed? You must have installed the scanner software in the new machine. Has it been updated for Windows 10 and changed somehow? I would have a good look at the tiff properties, in particular the color profile. There are different versions of sRGB. Gimp 2.10 does handle tiff files in a different way and has much more color management than Gimp 2.8 You can set a different RGB profile using `Image -> Color Management -> Assign Color Profile.

You thought the previous Gimp was 2.10.8 Maybe that was Gimp 2.8.something ? Gimp 2.8 does not have as much color management & jpeg options as 2.10
Download is https://download.gimp.org/mirror/pub/gim...-setup.exe This will replace your existing Gimp 2.10.x

Do your editing in Gimp. Export in some other format, say png. Convert the png to jpeg using some other application. I would try XnViewMP which is a free viewer/converter application. You can download a Windows version here: https://newsgroup.xnview.com/viewtopic.php?f=82&t=39812
