How can we help?
Start with documentation for the product you use, browse FAQs, or reach a human through contact. Each app also keeps its own always-current help pages on its subdomain.
Which page will answer your question fastest
Support here is split across four surfaces, and picking the right one usually saves more time than anything else. If you are trying to do a specific thing — make a transparent cutout, fill a PDF form, convert a file — go to the tutorials, which are step-by-step and written around one task each.
If you are trying to find out whether a feature exists at all, the tool maps are the fastest route: every tool and page in each app, listed with a one-line description and a direct link. If you want to understand how something works or where its limits are — file size caps, supported formats, what runs on your device versus a server — that is documentation.
For short, common questions about privacy, pricing, accounts, or browser support, the FAQ is grouped by product and answers most of them in a paragraph. Anything that is genuinely a bug, or is specific to your file, goes to contact.
Before you write in
Because the apps process files on your own device, we cannot see what happened on yours — there is no server-side log of your session to look at, which is the same property that keeps your files private. That makes the detail in your message the only diagnostic information available, so a few specifics turn a multi-round exchange into a single reply:
- Which app and which page.The apps live on separate subdomains and share almost no code, so “the editor” is ambiguous — a URL is not.
- Browser and device. Most hard failures are capability differences — WebGPU, WebCodecs, and available memory vary a lot between browsers and phones.
- The file, described not attached. Format, rough size, and anything unusual about it. Please do not send us your document — we would rather reproduce it with a sample from Novus Examples.
- What you expected versus what happened. Including the exact wording of any error message.
Documentation by product
Every app has a documentation page here on the hub, a tool map listing each of its surfaces, and a tutorials hub. The summary under each entry says what that app is for, so you can tell at a glance whether it is the one you want.

Hub docs vs in-app help
Each app also keeps its own help pages on its subdomain. Those are always the most current — they ship with the app, so they change the day a feature does. The documentation here on the hub is the wider view: what the app is for, how it fits alongside the others, and where its boundaries are. When the two disagree about a detail, trust the app.
If a question is about the hub itself — this site, the blog, our privacy and cookie handling, or advertising — the answers live in the FAQ, privacy policy, and cookie policy. Recent changes across every app are recorded on the changelog.
