Convertlix APK: What the Free Tier Includes

There is no working modified APK of Convertlix, because the thing a mod would have to unlock is not in the APK: sign-in and licence validation happen on the server, so a patched client can change what the screen says but cannot mint an entitlement the server did not issue. The more useful answer is that most people searching for one do not need Premium — the free tier runs all 24 tools, and what it caps is file size, batch size and a monthly conversion count, not features.

Convertlix is an Android app (8.0 or later) that converts on the phone itself: a file is opened through Android's own file picker, the work runs locally, and the result is written back to storage. Nothing is uploaded — its network calls carry identity, licence, quota, configuration and payment data only, never a document. Sign-in is required once and there is no guest mode; after that the tools work with the network off. On the free tier a single file can be up to 25 MB (50 MB for audio and ZIP, 100 MB for video), a batch can hold 5 items, and the monthly conversion count is a server-set allowance shown in the app rather than a number printed on a website.

What the free tier actually includes

The part people get wrong is that the free tier is feature-limited. It is not. Every one of the 24 tools is available on a free account — Compress PDF, Merge PDF, Split PDF, PDF Page Manager, Sign PDF, Images to PDF, Cam to PDF, the Image Converter, Image Resizer, Image Cropper, Photo Collage, Watermark Adder, PNG Optimizer, Social Media Resizer, Video Converter, Fix for TV, Audio Converter, Document Converter, OCR & Text Suite, File Compressor, Metadata Cleaner, Hash Checker, Batch File Renamer and the QR generator. The one thing Premium unlocks rather than raises is the styled QR codes.

What free limits is throughput and size:

Those are limits, and worth reading as limits. A 300 MB holiday video will not convert on a free account. Neither will a 40 MB scanned PDF, nor a batch of 60 photos in one pass. If that is your job, free is the wrong tier and no APK changes the arithmetic — the caps are enforced against the licence the server issues.

But the median job on a phone is well inside them. A phone photo is 2–6 MB. A typed PDF exported from Word is under 1 MB. A ten-page scan at 150 DPI greyscale lands between 1 MB and 3 MB, as Why Is My Scanned PDF So Large? works through. Under those conditions the 25 MB ceiling is not the thing you run into; the monthly allowance is, and only if you convert regularly.

Why a patched APK cannot unlock Premium

The honest reason is architectural rather than moral.

The entitlement lives on the server. Convertlix requires one successful sign-in, and the licence, quota and configuration state attached to that account is checked server-side. A modified client can hide a paywall, flip a boolean or draw an "unlimited" badge, and the server will still return the free tier's caps for that account. The screen changes; the ceiling does not. This is also why reinstalling the app does not reset the current month's usage — the count comes back with the account.

A repackaged APK is signed by someone else. Android requires every APK to be signed, and the signature is what ties a build to whoever produced it. A repackaged file has been re-signed with a different key, so the signature no longer tells you it is the same code that was published. You cannot diff a mirror's build against a published one from your phone, so "it's the same app plus a patch" is a claim you have no way to check.

And the privacy property depends on the binary being the real one. The whole argument for converting on the phone is mechanical: the file is handed over by Android's picker, processed locally, and no copy goes anywhere. That property is a property of this code. A build somebody else compiled and signed could add network calls that do carry the document, and the airplane-mode test would not catch a build that queues uploads for later. A file tool you can trust never receives the file — but you only know it never received it if you know what you installed.

On malware, the factual position is enough without embellishment: repackaged APKs are a known distribution route for injected code, because a converter is handed exactly the files a user cares about and runs with whatever permissions its manifest requests. Convertlix asks for no storage permission at all — it uses Android's file and photo pickers, which hand the app one file you chose — and one camera permission used only by Cam to PDF. A re-signed build can request whatever it likes, and a manifest you did not read is a permission set you did not agree to.

How to set Convertlix up on the free tier

1. Install the app from a source you can verify. The package name is com.profazia.convertlix, published by Profazia. Check the package name before you sign in — a lookalike with a different package id is a different app.
2. Sign in once, while you have a connection. This is required and there is no guest mode. The sign-in is what creates the licence and quota state the app reads, and the marker it leaves does not expire.
3. Turn the network off and convert something. This is the honest test of the privacy claim, and it takes thirty seconds. Every tool should still complete with airplane mode on. If a file tool needs a connection to convert, the file is going somewhere.
4. Check the size of your file before you pick it. Free caps are 25 MB per file, 50 MB for audio and ZIP archives, 100 MB for video. Knowing the cap before you start saves the failed attempt.
5. Work in batches of 5. That is the free batch ceiling, except Images to PDF which takes 20. For a long run of photos, several passes of 5 cost the same number of conversions as one pass of 20 would — one per successful job — so plan around the job count, not the file count.
6. Only consider Premium once you actually hit a wall. If you have not seen a size or allowance error, you do not need it yet.

What Premium adds, and what it does not

Premium raises the per-file ceiling to 2 GB, batches to 200 items, makes conversions unlimited, and unlocks the styled QR codes. It is from $9.99/mo or $99.99/yr (USD base; your local price is shown at checkout, and many countries are priced in local currency with tax included). It works on one device at a time and is tied to your email address, so moving to a new phone takes a sign-out rather than a second purchase — and sharing one subscription across a household does not work.

What it does not do is change where the conversion happens. There is no "Premium cloud" that would be faster; Premium jobs run on your handset exactly as free ones do. Which means Premium buys you headroom, not a different product — and it is the honest reason a mod APK is a poor trade even setting aside that it does not work. The thing being "unlocked" is a quota, and the quota is the cheap part.

When free is genuinely not enough

• Long video. A 20-minute 4K clip is well past 100 MB, and often past 2 GB once you account for the source. For that job a desktop tool such as HandBrake is free, runs locally, and will beat any phone on encode time — it just needs a computer.
• Bulk work. Renaming or converting 200 files in one pass is a Premium batch size. Under free you are doing 40 passes of 5.
• Regular daily use. The monthly allowance is shared across all 24 tools and resets on the UTC calendar month. Successful jobs cost one conversion each; failed, cancelled or timed-out jobs cost nothing. If you convert several files most days, you will meet it.
• PDF to Word. Convertlix does not have this tool at all, on either tier. The Document Converter goes into PDF, DOCX or TXT, and OCR pulls text out of scans; neither reconstructs an editable Word layout from a finished PDF.

FAQ

Is there a Convertlix mod APK or cracked version?

Not one that unlocks anything. Convertlix validates the licence and the conversion quota on the server against the account you signed in with, so a patched client can alter what the interface displays but cannot make the server grant Premium limits. Any build that claims otherwise has been re-signed with someone else's key, which means you have no way to verify it contains the same code.

Is the free tier enough for most people?

For occasional phone-sized jobs, usually. All 24 tools are available on free; the caps are 25 MB per file (50 MB audio and ZIP, 100 MB video), batches of 5, and a server-set monthly conversion allowance shown in the app. Where it stops being enough is long video, bulk batches, and using it most days — those are the three walls people actually hit.

Does Convertlix work offline?

Yes, after one successful sign-in. A new installation needs a connection for that first sign-in and for licence, quota and payment calls; once the marker exists, every tool converts with mobile data and Wi-Fi off, and the marker does not expire. Airplane mode is the honest test of the claim that the file is never uploaded.

Does Convertlix upload my file?

No. The file is opened through Android's own file picker or photo picker, converted on the phone, and written back to storage, so no copy is sent anywhere and nothing sits on a server to be deleted later. Its network requests carry identity, licence, quota, configuration and payment data only. The app asks for no storage permission, so it cannot read anything you did not hand it — which is also why a build signed by someone other than the publisher voids the whole argument.

What exactly does Premium change?

It raises the per-file ceiling from 25 MB to 2 GB, batch size from 5 to 200 items, makes conversions unlimited instead of a monthly allowance, and unlocks the styled QR codes. It is from $9.99/mo or $99.99/yr (USD base; local price shown at checkout), and works on one device at a time. Conversion still runs on the phone — Premium does not move anything to a server.

If you came here for a shortcut past the paywall, the shortest honest one is to check whether the paywall is in your way at all: run Merge PDFs Without Uploading Them Anywhere or Compress a PDF Under 2 MB on Android (Free) on a free account and see whether you ever meet a cap.
