No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. A small install base leaves thin data to model from.

    You might wonder why you need this plugin when the “Convert to blocks” button is right there at the top of every Classic block. Well, click that and it will eff up any images you had using the <figure class=”alignleft”> (or alignright) code. The default WP “convert to blocks” strips out the figure code entirely and POOF your alignment class is gone and your caption is off god knows where. But not this plugin! Add this and when you open your classic page in the block editor, it preserves the figure tag and alignment class. Saved me having to redo image settings on 600 post. Thank you 10up.

    All this does is convert posts into HTML blocks, same as happens if you manually tell WordPress to convert a classic HTML post to blocks. Ok, it saves a single mouse click… why install a plugin to save one mouse click?

    When you run a command and open a URL, the browser opens articles one after another and converts them into blocks. It magically automatically converts blocks quickly and accurately. This topic was modified 2 years, 2 months ago by megane9988.

    Saves me a lot of time. Used it two times on large projects. I did not try the bulk option, but I just read that it can have bugs or crashes. Probably due to server load or unusual post content? What I did instead was create a button that that when pressed automatically opens in a new tab the 20 posts from the Posts Table view. I then waited for them to load. After they were all loaded I went to each page and updated the page. I then waited a while for all of them to be saved and double checked in the Posts Table if all the posts were converted to the Block editor. The little icon showing if the post is Classic or Block comes very handy! Once I confirmed that all 20 posts from the Posts Table view were converted I moved to the next page and repeated the process. This semi-automated process helps prevent “bugs” or perhaps random server spikes. I was running this on my own private cloud server with little resources. Surprisingly saving 20 posts at once was possible without any crashes. I did not have any bugs or issues. Thank you for creating this plugin!

    I have a load of old posts and pages done in the original WP editor which desperately needed converting to blocks in order to play nicely with a child theme I was working on. We know the block editor has the facility to go through posts/pages one-by-one and convert to blocks – but this is painful…. This plugin seems to do that job for you, but silently in the background. Once I’d activated it and saved the settings, nothing happened….at least, not visually. It was only when I started to look at the entries made in the legacy editor that I could see they had been converted to block format – silently! The only improvement I can suggest is a message on the plug-in interface page which says something like, “when you have ticked the checkboxes, press the save button and your conversion will commence as a background task.” I don’t know if that would make sense in keeping with the way the plug-in works. I only have a couple of hundred posts so it did the job quickly. I don’t know how it would perform on a site with thousands of old posts in legacy editor format. Either way, thanks to the author for saving me the time.

    Very good plugin, which helps to migrate a lot of posts. We have a project with ~8000 posts, which needs to be converted. Only standard text and images… Unfortunatly WordPress itself is pushing Gutenberg, but not providing tools for this task. This plugin is helping a lot. Basically it opens the browser, clicks the button, saves the post, opens the next post … A quite clever solution, which unfortunately is slow and sometimes breaks.. Means you have to monitor the task and reload the tab from time to time… This topic was modified 2 years, 8 months ago by Adrian Mörchen.

    This is the only plugin that is actively maintained and gets the job done. I see that in the next revision it will receive basic settings on which post types it works on, but until then, read the support for the solution to the problem that you have lost Gutenberg on all custom post types.
