Will my HTML work?
Start with one HTML file up to 2 MB, with its styles and scripts embedded. Interactive buttons, calculations, charts and animations can run inside the preview.
Best fit
- Single .html or .htm files
- Embedded CSS, JavaScript and images
- Responsive layouts with touch-friendly controls
- HTTPS resources when their provider allows them
Current limits
- No companion folders, ZIP files or server-side code
- Browser storage and service workers are restricted
- No camera, microphone, location or popup access
- Inputs inside a tool are not saved by PocketPages
Phone/Desktop changes the preview width. It does not rewrite your layout. Dark mode changes PocketPages; your HTML keeps its own colors. External scripts and forms may send entered information to other services.
What to ask the HTML creator
“Export one self-contained HTML file under 2 MB. Embed styles, scripts and assets. Make it responsive with a viewport tag and touch-friendly inputs. Avoid local storage, service workers, popups and server-side code. Clearly explain any internet dependency.”

These checks use the same sandbox as your uploaded file. Mark the result you actually observe. Nothing is marked passed automatically. Your observations stay in this tab until you copy them; reloading clears them.
Expected: Change either number. The total should update immediately. Open the phone keyboard and check that inputs stay reachable.
