Someone spends four minutes on your quote form. Name, company, budget range, a long note about what they need. Then the tab freezes, they refresh out of habit, and every field is empty. They do not fill it again. They leave.
That is not a “conversion rate mystery.” It is a draft that never got saved. WordPress forms still treat the browser like a disposable notepad. Refresh, back button, accidental navigation, a service worker update mid-type. Any of those can wipe unpaid work.
Progressify is the DaftPlug PWA plugin that turns your site into an installable app experience. One piece that quietly protects leads is Autosave Forms: it persists form data after a refresh so people do not start over.
What Progressify actually ships for form autosave
Nothing invented here. For this post you get:
- Autosave Forms. Persist form data after refresh.
- Related context that sits next to it: a branded offline page, background sync for comments/forms/cart, the service worker, install prompt styles (banner, popup, overlay, button, QR), push from wp-admin, and app-like UI pieces (tab bar, transitions, dark mode).
Autosave is the “draft survived” feature. Background sync is the “submit while offline, replay later” feature. You can use both. This article is about drafts that survive a refresh, not about queueing a POST for later.
If you want the companion setup for the offline shell itself (branded offline page plus cache rules), read WordPress PWA branded offline page and cache rules.
Why refresh kills forms more often than you think
Most site owners test forms on a calm desktop with perfect Wi‑Fi. Real visitors do messier things:
- They open your form in a mobile browser, switch to Messages, come back, and the tab reloads.
- They hit refresh because the CAPTCHA looked stuck.
- They rotate the phone and a broken theme re-renders the page.
- They use “Open in app” / install prompts and land back on a fresh document.
- A parent page navigation (logo click, sticky menu) nukes the form without a confirm dialog.
Every one of those is a blank form unless something persisted the fields. Browser autofill helps for email and name. It does not restore a multi-paragraph message, a selected package, or a WooCommerce-adjacent quote field you built in Gravity Forms / Contact Form 7 / Fluent Forms.
Autosave Forms exists for that gap. The data stays with the visitor’s browser across a refresh. They see their draft again and keep typing.
How to set this up in WordPress with Progressify
Assume Progressify is installed and the PWA core (manifest + service worker) is already on. Autosave Forms is a front-end persistence feature. It still wants a healthy worker and a site that loads reliably.
1. Open Progressify and enable Autosave Forms
In wp-admin, open Progressify settings. Find Autosave Forms (it may sit near offline / forms / service worker options depending on your layout). Turn it on.
You are asking the plugin to persist form field values so a refresh does not wipe them. Keep the wording in your head: persist after refresh. That is the contract.
2. Confirm the service worker is controlling the page
Chrome → DevTools → Application → Service Workers. Progressify’s worker should be registered and active. If the worker is missing, fix PWA enablement first. Autosave and other offline-adjacent features assume the PWA stack is actually running on the front end.
3. Pick the forms that matter (and test those first)
You do not need every newsletter popup autosaved on day one. Prioritize:
- Contact / lead forms
- Quote or RFP forms with long textareas
- Application or onboarding forms with many fields
- Support forms where people paste error logs
Open each form on a phone and on desktop. Fill half the fields. Refresh. The values should come back. If a particular builder posts through a weird iframe or shadow DOM, verify that form in a real test instead of assuming every plugin markup is identical.
4. Pair autosave with a branded offline page (and sync if you need it)
Autosave helps when the page reloads. A branded offline page helps when the network is gone and they still need a clear screen. Background sync helps when they hit Submit offline and you want the submission queued and replayed later.
Those are three different moments:
| Moment | What Progressify covers | | — | — | | Refresh mid-type | Autosave Forms | | Offline browsing | Branded offline page + cache rules | | Offline submit | Background sync for forms (and comments / cart when relevant) |
Ship autosave first if your biggest leak is “they typed, then refreshed.” Add sync when “they submitted offline and nothing arrived” is the complaint.
5. Install prompts after trust, not before
Install prompt styles (banner, popup, overlay, button, QR) are useful once the site feels app-like. App-like UI (tab bar, transitions, dark mode) and push from wp-admin are retention tools. None of them replace a form that forgets the draft. Get autosave working, then invite install.
What good looks like
A solid Autosave Forms setup feels invisible:
- Half-filled forms survive a hard refresh.
- Back/forward into the form page still shows what they typed (when the browser restores the document from bfcache or a reload path you tested).
- Long textareas come back intact, not just email and name.
- People are not asked to “draft in Notes and paste later.”
- Your lead volume stops dipping on mobile for no SEO reason.
On a membership or SaaS-style WordPress site, good also means you do not surprise people with stale data from a week-old tab if that would be wrong for your flow. Test the happy path: fill, refresh, continue, submit once. Then test abandon: fill, leave for a day, return. Decide whether restoring that draft is still helpful. For most contact forms, yes. For checkout-adjacent flows, verify carefully.
Pitfalls (the ones that bite)
Confusing autosave with background sync. Autosave persists drafts after refresh. Sync queues submissions offline. Different problems. Enable the one you actually need, or both on purpose.
Only testing the default Contact Form 7 demo. Your real form has conditional fields, file inputs, and multi-step logic. Test the production form.
Expecting file inputs to “autosave” like text. File pickers are a special case in browsers. Do not promise visitors that an uploaded PDF will survive refresh unless you have verified that path. Text and selections are the win.
Skipping mobile. Most draft loss happens on phones. Use a real device, not only DevTools device mode.
Turning on every install prompt style at once. One clear prompt beats three overlays fighting the form.
Ignoring the offline page. If they go offline mid-form, they need honest copy: you are offline, your draft should still be here when you reconnect, then submit. Vague errors train abandonment.
Assuming desktop autofill is enough. Autofill does not restore custom fields and long messages.
Practical checklist before you call it done
- Enable Autosave Forms in Progressify.
- Confirm the service worker is active.
- Fill a lead form halfway → refresh → confirm fields return.
- Repeat on iOS Safari and Android Chrome if those are your traffic.
- Submit once successfully so you know the form still posts normally.
- Optionally enable background sync for forms if offline submit matters.
- Keep one install prompt style, not five.
Takeaway
WordPress forms lose money when drafts die on refresh. Responsive design does not fix that. A PWA stack can.
Progressify gives you Autosave Forms so field data persists after a refresh, plus the surrounding PWA pieces (branded offline page, background sync, install prompts, app-like UI, push from wp-admin) when you are ready for them. Start with the forms that take more than thirty seconds to fill. Those are the ones people abandon when the page blinks empty.

Ship autosave. Then refresh a half-filled form on purpose. When the text is still there, the feature earned its place.
