Many Others
Often, users have expressed that they need a quick InDesign previewer, not always a full-blown editor. Some have owned InDesign in the past, while others receive INDD, INDT (InDesign Template), or IDML files from colleagues and clients from time to time. We are happy to offer a fast and affordable solution.
IDMarkz can preview InDesign and IDML files, allowing you to inspect document content without requiring Adobe InDesign. Previews are based on the internal document data, so there is no need to save files with embedded previews. The displayed preview is representative of the original document, with crisp, zoomable text and detailed page rendering for easy review.

I recently purchased IDMARKZ because I am running an older Mac and found out I can no longer upgrade to the most recent versions of Adobe Cloud products without replacing my perfectly good iMac. I have started getting files in the higher version of InDesign, and I hated to have to go back to the customer to ask them to save it back a version if they didn’t include an .idml file when they packaged it. It’s a great product and I wish I had gotten it sooner!

Without reservation, I can honestly say that the program IdMarkz literally saved my quite extensive sermon library from being lost.
I had used InDesign for many years, an excellent program, but far too expensive for the average desktop publisher like myself.
I discovered a brilliant program called ‘Affinity Publisher.’ It may not have the bells and whistles of InDesign, but it’s more than enough capable to run up books and magazines that won’t disappoint.
My problem came when I decided to switch over to Publisher. InDesign did not provide an easy export route for me to save thousands of sermon files I had composed. To tell the truth, I was a little bit in panic mode…even thinking of returning back to the expensive InDesign.
While trying to find a solution for my problem, I came across IDMarkz. It promised to restore my files back into a usable format by using Affinity Publisher. I bit the bullet, paid for and downloaded the IDMarkz program, and ‘Wallar!’ All the files I couldn’t convert all safely converted.
I can honestly say the IDMarkz has proved to be a godsend.
Markzware Hi, I’ll use it whilst browsing files in the finder/file open window within InDesign (I don’t really like using Adobe Bridge!) I use quick view everyday for jpgs, pdfs word files etc and it frustrates the [heck] out of me that Apple/Adobe don’t get this working for their apps - We used to purchase “Artview” from Codeline which did the same but their product doesn’t work with the latest OS/Creative Cloud versions - I used to use Markzware stuff years ago as we had a lot of crossover with Quark files etc but we only ever use inDesign now and don’t really need to convert files anymore. So pleased that I found this today though as I just had to trawl through hundreds of archived Indesign files looking for something specific - without quick view I would have had to open each one in turn!
Not only does IDMarkz convert newer InDesign files to IDML, it also exports files for Affinity Publisher. And with excellent fidelity. So glad I found this tool with the help of their excellent Customer Service, Technical support, and Sales teams.

While working on an InDesign document, the file started acting crazy and I could not get it to work properly. I contacted Markzware to see if they could help, and they bent over backward to accommodate my needs. I highly recommend IDMarkz!
Just discovered new magic in the form of IDMarkz. Now I can open, convert and use dozens of old InDesign files I didn't convert when I choose to not pay a monthly subscription/rent/ransom to Adobe and switched to the powerful Affinity suite of Publisher/Designer/Photo—highly, highly recommended, reasonably-priced, unexpectedly capable graphics tools for professionals. Bravo IDMarkz!
Wonderful tool, does everything I needed :-) Easy to download and easy to use. Thank you so much, this will make my life so much easier!
Markzware ROCKS!!!!
I'm obviously not the only one who is sick of being forced to work around Adobe's constant attempts to screw more cash out of users who have supported their products for DECADES already. Well, I would prefer to give my money and support to third-party software developers like Markzware, who are actually committed to providing products that HELP their customers. Their products are excellent, and the support is absolutely fantastic too.
Love it!

Of course I switched to Affinity. Never think back. Affinity + @Markzware IDmarkz to convert Indesign files.
