Zamzar File Size Limit: 50 MB, 2 Files a Day
Zamzar's free limit is 50 MB and 2 files per 24 hours — and over 50 MB it converts, then blocks the download. What that means and what to do instead.
Zamzar's free tier is limited to 2 files per day — restated on their signup page as 2 files per 24 hours — with a 50 MB free file size limit stated on their homepage. The detail that catches people out: exceeding 50 MB does not stop the conversion. It runs, and then, in Zamzar's own words, "You will need to create a paid Zamzar account to be able to download your converted file." You can watch a job complete and still be unable to retrieve the result. All figures as of September 2026 — check Zamzar's pricing before planning around them.
If the file fits on a phone, Convertlix avoids the whole shape of that problem: it is an Android app (8.0 or later) that converts on the handset, opening the file through Android's own picker, so nothing is uploaded and there is no paywall between the conversion and the file — the result is written straight back to your storage. Sign-in is required once, with no guest mode; after that the tools work with the network off. Free files are capped at 25 MB (50 MB for audio and ZIP, 100 MB for video), batches at 5 items, and the monthly conversion count is a server-set allowance shown in the app. That per-file ceiling is lower than Zamzar's 50 MB, which is worth being clear about up front.
Converted, then blocked at download
This is the most searchable frustration with Zamzar and it is not a bug. The free limit is enforced at the download step rather than the upload step. Your file goes up, the conversion happens, the job reports as finished — and the download is gated behind a paid account because the input exceeded 50 MB.
Two things follow from that, and both are worth knowing before you start:
- The time is spent either way. Uploading a 120 MB video on a phone connection and waiting for the conversion is real minutes, and none of it is refunded by the block. The upload is also the half of a cloud conversion you cannot speed up.
- The file has already been transferred. By the time you learn you cannot download the result, the input has been on their servers for the duration of the job. That is not a criticism of their handling of it — see the retention section — but it is a fact about sequence that a size check beforehand avoids.
So the practical advice is boring and effective: check the file size before you upload, not after. Anything over 50 MB on a free Zamzar account is a job you cannot finish.
The free limits, as of September 2026
| Free-tier limit | Zamzar (Sept 2026) | Convertlix free |
|---|---|---|
| Job count | 2 files per day (2 per 24 hours) | A server-set monthly allowance shown in the app |
| Max file size | 50 MB; over that, download is blocked | 25 MB (50 MB audio/ZIP, 100 MB video) |
| Where it runs | Their servers | Your phone |
| Formats | 1100–1200+ claimed | 24 tools across PDF, image, video, audio, document, utility, QR |
| Retention | Free: stored securely up to 24 hours. Paid: until you delete | None — there is no server copy |
| What you lose | Download blocked over 50 MB; 2 jobs a day | A lower per-file ceiling; Android only |
Note that Zamzar's limits are per day, not per month. Two files today, two more tomorrow. For a one-off job that is a perfectly sensible free tier; for an afternoon of clearing a backlog it is the binding constraint, and it is the reason people search for the limit in the first place.
For context, their paid tiers as of September 2026 raise the per-file ceiling: Basic at $12/mo (200 MB), Pro at $19/mo (400 MB), Business at $39/mo (2 GB).
What Zamzar does better, plainly
- Format breadth. Zamzar claims support for 1100–1200+ format conversions. That is far beyond what any 24-tool phone app covers, and if your format is unusual, breadth is what matters most.
- A 50 MB free ceiling with no format restriction. Double Convertlix's 25 MB general cap, and it applies across their catalogue rather than to a subset.
- Nothing to install for a one-off job. If you need one conversion, once, from a borrowed computer, a web tool is the right tool and an app install is overhead.
- Email-when-done, and a stored file library. Start a long conversion, close the tab, get a mail. A phone app that converts locally cannot offer that, because there is no server holding the job.
- A desktop app. For repeat work on a computer, that is a real product a mobile-only toolkit does not have.
Retention: a library is a feature and a fact
Zamzar's stated policy, as of September 2026: free users' converted files are stored securely for a maximum of 24 hours; paying users' files are stored until they choose to delete them; and all users can delete sooner than that.
It is worth stating both halves honestly. Indefinite retention on paid plans is a deliberate feature — it is a file library, and if you convert the same set of documents repeatedly, having them there is exactly what you are paying for. Calling that a privacy failure would be dishonest.
It is also, for a privacy-motivated searcher, the fact they came to find. Files that stay until you delete them are files that exist somewhere until you delete them, and every consequence of that follows from the same architecture — one that has to receive the file before it can convert it.
The Convertlix argument here is architectural and nothing else. There is no retention policy because there is nothing to retain: the file is opened through Android's picker, converted on the phone, and written back. A file tool you can trust never receives the file. Verify it the cheap way — sign in once, switch on airplane mode, convert something. The same reasoning is worked through in Remove GPS and EXIF Data From Photos (Android), where the whole point is a file you would rather not hand to a server at all.
How to get past Zamzar's 50 MB free limit
- Check the file size before you upload. On Android, long-press the file in Files and read the size. Over 50 MB, a free Zamzar job will convert and then refuse the download, so knowing first saves the entire upload.
- Shrink the input rather than paying for the ceiling. A 60 MB scanned PDF is usually 60 MB because of image resolution and colour depth, not page count; Why Is My Scanned PDF So Large? covers what actually makes it big and Compress a PDF Under 2 MB on Android (Free) covers getting it down.
- Split the job if the format allows. Two 40 MB halves are two jobs — which is exactly your free daily allowance, so it works once per day and not twice.
- Do it locally if the file is phone-sized. Under 25 MB, or 100 MB for video, Convertlix converts on the handset with no upload, no download gate and no daily job count — just the monthly allowance the app shows you.
- Pay for the tier if the format is the reason you're there. If you need a conversion Zamzar supports and a phone toolkit does not, their Basic plan at $12/mo for a 200 MB ceiling (September 2026) is the honest answer, and a cheaper one than working around it.
When Convertlix is the wrong choice here
- Your file is between 25 MB and 50 MB and isn't audio, ZIP or video. Zamzar's free ceiling is higher than Convertlix's free one for that band. Premium raises it to 2 GB at from $9.99/mo or $99.99/yr (USD base; local price shown at checkout), but that is a paid step against their free one.
- Your format is exotic. Against 1100–1200+ claimed conversions, 24 tools is a narrow set. If yours isn't among them, breadth wins.
- PDF to Word. Convertlix does not have this tool. The Document Converter goes into PDF, DOCX or TXT and OCR pulls text out of scans; neither rebuilds an editable Word layout from a finished PDF.
- You want a stored library or an email when it's done. Both require a server holding your file, which is the thing being deliberately given up.
- You are not on Android. Convertlix is Android only, 8.0 and later. On a desktop, HandBrake for video and LibreOffice for documents are free and keep the file on your machine.
FAQ
What is Zamzar's free file size limit?
Zamzar's homepage states a 50 MB free limit as of September 2026. Above that the conversion still runs, but their notice says you will need to create a paid account to download the converted file — so the block lands at the download step, not the upload. Their paid tiers raise the ceiling to 200 MB (Basic, $12/mo), 400 MB (Pro, $19/mo) and 2 GB (Business, $39/mo).
How many files can I convert free on Zamzar?
Two files per day on the free tier as of September 2026, described on their signup page as 2 files per 24 hours. It is a daily allowance rather than a monthly one, so it resets, but it also means a backlog of five documents takes three days. Check their pricing page for the current figure.
Why can't I download my converted file from Zamzar?
The usual reason is that the input was over the 50 MB free limit. Zamzar performs the conversion and then gates the download behind a paid account, so a job that appears to have finished successfully can still be unretrievable. Checking the file size before uploading is what avoids spending the upload time for nothing.
How long does Zamzar keep my files?
As of September 2026 their policy states free users' converted files are stored securely for a maximum of 24 hours, while paying users' files are stored until they choose to delete them; all users can delete sooner. The indefinite paid retention is a deliberate feature — it gives you a file library — and it is also the thing to know if you would rather your documents not sit on a server.
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 your storage, so there is no upload, no server copy and no retention window to reason about. Its network requests carry identity, licence, quota, configuration and payment data only, and it asks for no storage permission. Sign in once, turn on airplane mode, and every tool still converts.
If the file is already under 25 MB, the 50 MB question never comes up and neither does the two-a-day count; Turn Photos Into One PDF for an Upload (Android) is the same task done on the handset.
