Fill & Sign mobile retired in 2025

Looking for an alternative?

Adobe retired the Fill & Sign mobile app. JustFill picks up the Fill workflow — and handles scanned, flat, and complex PDFs Acrobat can't touch.

Focused on the Fill part. For signatures you can insert a signature image; for drawn or typed e-signatures with audit trails use a dedicated tool.

Six reasons people are switching

Adobe Fill & Sign covered a narrow slice of form work. Here's what JustFill does differently.

The mobile app is gone

Adobe retired the Fill & Sign mobile app in 2025 and now directs users to the Acrobat Reader mobile app. If you relied on the dedicated Fill & Sign app, you need a replacement — JustFill runs in any mobile browser with no install.

Works on scanned and flat PDFs

Adobe Fill & Sign shows "greyed out" tools on PDFs without interactive form fields, password-protected documents, or scanned images. JustFill draws fields on top of any PDF visually — scans, flat forms, or exported Word documents.

No Acrobat subscription required

Adobe's Fill & Sign replacement path leads into Acrobat subscriptions starting at $12.99/month. JustFill has a permanent free tier where you can draw fields and fill any PDF without paying, and paid plans start at $9.99/month with AI-powered field detection.

AI detects fields automatically

Drawing every field by hand on a 5-page form is tedious. On paid plans, JustFill analyzes your document and creates fillable fields for you — text lines, checkboxes, signature areas, even in complex tables. You review and adjust, then fill.

Reusable templates for recurring forms

Every time you open the same form in Adobe you place fields again. JustFill saves your field layout as a template. Next month, upload the new PDF and the fields appear in the right place — you just fill in the new data and download.

Voice dictation built in

JustFill includes voice dictation in English, Polish, German, French, and Spanish. Click the microphone, speak your data, and it's transcribed into the right fields. No equivalent feature in Adobe Fill & Sign.

JustFill vs Adobe's form-filling options

A side-by-side look at how the options compare on availability, cost, and what each one can actually do.

Common Adobe Fill & Sign problems, solved

If any of these sound familiar, JustFill handles them differently.

Fill & Sign tools greyed out

Why it happens

The PDF has security restrictions or no interactive form fields. Acrobat can only fill AcroForm PDFs.

How JustFill handles it

JustFill draws fields on top of the image — restrictions don't matter because the original is untouched until download.

"Unsupported content" error

Why it happens

Acrobat can't recognize the document structure — common on scans, photographs of forms, or PDFs generated from unusual sources.

How JustFill handles it

JustFill treats every PDF as an image and lets you place fields anywhere, regardless of how the file was produced.

No more mobile app

Why it happens

Adobe retired the dedicated Fill & Sign mobile app in 2025. The migration path is to install the full Acrobat Reader mobile app.

How JustFill handles it

JustFill runs in mobile Safari, Chrome, and Firefox. Nothing to install. Touch interface for drawing and typing fields.

Can't save as a reusable template

Why it happens

Adobe Fill & Sign has no template feature — every time you open the same form you place fields again.

How JustFill handles it

Save your field layout once. Next time the same form opens, fields are already in place.

Subscription required for anything beyond basics

Why it happens

Acrobat Standard starts at $12.99/month, Pro at $19.99/month annually, and advanced AI features are in the $24.99/month Studio tier.

How JustFill handles it

JustFill has a permanent free tier. Paid plans start lower than Acrobat Standard and include AI features Acrobat charges extra for.

Frequently Asked Questions

Adobe consolidated the Fill & Sign mobile app into the Acrobat Reader mobile app in 2025. The dedicated Fill & Sign app is no longer available for download and users are directed to install Acrobat Reader instead. The stand-alone app will not receive further updates.
JustFill replaces the core Fill & Sign workflow — drawing text fields on a PDF, typing values, and downloading the filled document. It also covers scenarios Adobe Fill & Sign never handled well, like scanned PDFs and flat forms without AcroForm fields. For advanced Acrobat features like Bates numbering, redaction for compliance, or PDF/A archival output you still need Acrobat Pro.
JustFill focuses on the "Fill" part of Adobe Fill & Sign — filling text, checkboxes, and data fields on any PDF. For signatures, you can upload a signature image (photograph or pre-made PNG/JPG of your signature) and place it where a signature is needed. JustFill does not currently include a draw-by-mouse signature pad or typed cursive signatures. For basic free self-signing with a drawn signature, Adobe Acrobat Reader on desktop and mobile remains a good free option. For legally binding e-signature workflows with audit trails, multi-party signing, and compliance (eIDAS, ESIGN Act), use DocuSign, Dropbox Sign, or Adobe Acrobat Sign.
Yes. Open JustFill in Safari or Chrome on iOS, upload your PDF, draw fields with your finger, and download the filled document. No App Store install, no Adobe account. It also works on Android and any mobile browser.
The most common reasons are a password-protected PDF, a document with editing restrictions set by the author, or a scanned image saved as PDF without recognizable form fields. JustFill avoids these restrictions because it places fields on top of the PDF image — the underlying file is not modified until you download the filled version.
JustFill has a permanent free tier that covers basic form filling with no watermarks and no time limits. Paid plans start at $9.99/month compared to Adobe Acrobat Standard at $12.99/month (annual) or Pro at $19.99/month (annual). Adobe Acrobat Studio with AI Assistant is $24.99/month — JustFill includes AI field detection on its paid plans.
You can preview the interface and basic features without an account. To save templates, use AI detection, or fill more than a few documents you need a free account. No credit card is required.
Filled PDFs you already downloaded from Adobe Fill & Sign remain yours — they are standard PDF files. JustFill opens and works with any PDF, including ones originally filled in Adobe. You can upload an Adobe-filled PDF to JustFill and continue editing, adding more fields, or filling additional data.
No. JustFill is an independent tool built and maintained by a separate company. Adobe and Adobe Fill & Sign are trademarks of Adobe Inc. — JustFill is not affiliated with, endorsed by, or sponsored by Adobe.
Adobe Fill & Sign did not use a portable template format, so there is nothing to import. In JustFill, upload the same blank PDF you used in Adobe, draw or auto-detect the fields once, and save as a JustFill template. From then on that layout is reusable.
Files are uploaded to JustFill servers only when you explicitly trigger AI analysis or save a document — otherwise rendering happens in your browser. All transfers use encrypted connections and JustFill is GDPR compliant. You can delete your account and data at any time.
If you mostly filled forms in Fill & Sign (the free workflow) and only need field filling, JustFill covers it at lower cost with better support for scanned and flat PDFs plus AI detection. If you need Acrobat Pro's full PDF editing, OCR, redaction, and compliance features, keep your subscription — JustFill is not a full Acrobat replacement.
