Overview

MConverter brings video, audio, image, e-book, document, subtitle and archive conversion into one service. It can convert multiple files together, including different source formats to a single target format, and folder input reaches compatible files in subfolders. That makes it a practical fit for varied collections and repeat jobs, rather than just isolated, single-file conversions.

Files can be selected from Google Drive, Microsoft OneDrive and Dropbox. A Google Workspace Marketplace app supports conversion in Drive, while an API enables automated file conversion and PDF compression, including integrations with Make.com and similar platforms. These options are most useful when conversion is part of a recurring workflow; they matter less to someone who only needs an occasional file converted.

Key features

Batch and folder input reduce the work of assembling mixed queues. The free plan, however, allows only eight files at once and 15 files per day, with a 100 MB limit per file. That is enough to try the service or handle modest workloads, but not a good fit for frequent high-volume use or files beyond that size.

MConverter says each file is converted in a separate isolated environment, limiting interference between users' jobs. It says transfers use TLS 1.3 and HSTS, uploaded files are deleted from its servers four hours after conversion, and users can delete them immediately. The company also says it processes files in-house, does not share files with third parties for advertising or marketing, and uses cloud providers with ISO/IEC 27001 and SOC 2 certifications. Those are meaningful safeguards for an online converter, though they do not change the practical consideration that files are uploaded to a service.

Pricing

The free plan costs 0.00 USD per free and permits 15 files per day, eight files at once and 100 MB per file. It is the sensible option for light use, but the daily quota and size ceiling can quickly rule it out for regular queues.

Plus costs 12.99 USD per month, billed monthly. It raises simultaneous processing to 250 files, permits files up to 1 GB and removes the daily conversion limit; it also removes ads and includes human customer support. This is the entry paid tier for people whose main needs are more throughput and larger files.

Pro costs 25.99 USD per month, billed monthly, and raises the limits to 750 files at once and 2 GB per file, with unlimited daily conversions and priority human support. Max costs 33.99 USD per month, billed monthly, and allows 1,000 files at once and 10 GB per file, also with unlimited daily conversions and priority support. Pro suits larger queues than Plus can accommodate; Max is the relevant step up when the 2 GB file ceiling is the blocker. A One-Day Pass offers full access for 24 hours, all Plus features and no subscription, with custom pricing; it fits a short burst of work better than an ongoing monthly plan. The paid plans are billed monthly, so their higher limits come with a recurring cost rather than a one-off purchase.

Platforms

MConverter supports web, Android, iOS, Linux, macOS and Windows, as well as an extension and API. That range accommodates both browser-based use and automated workflows across platforms.

Who it's for

MConverter is a strong match for people converting mixed file types in batches, working with folders or cloud-stored files, and teams or individuals automating conversion through an API. Occasional users can start on the free plan. Anyone with sustained high volume or files larger than 100 MB will need a paid tier, while users who do not need cloud access, folder handling or automation may have little reason to pay for those capabilities.

Pros and cons

Pro: Batch conversion accepts different source formats for one target, and folder input can include compatible files in subfolders, reducing manual queue preparation.
Pro: Drive, OneDrive and Dropbox selection, a Drive app and an API support cloud-based and automated workflows.
Pro: Paid plans scale from 1 GB to 10 GB per file and remove the daily conversion cap, with support included at each paid level.
Con: The free plan's 15-file daily quota, eight-file batch limit and 100 MB ceiling make it unsuitable for steady or large-file work.
Con: Pro and Max cost 25.99 USD per month and 33.99 USD per month respectively; their larger limits only make sense when the lower tiers' caps are genuinely restrictive.

Alternatives

For a broader list of file conversion software, consider how much batch capacity, platform support and workflow automation matter before choosing a service.

AnyConv is a free alternative with no registration, up to 60 files per hour and a 100 MB maximum upload; choose it when an hourly allowance and no-account use matter more than MConverter's cloud selection or API.
Freemake Video Converter offers core conversion features free with no expiration and a Mega Pack lifetime license; it is an option for those who prefer a free, non-expiring core offering.
HandBrake is free software for Linux, macOS and Windows; choose it if those desktop platforms and a free tool are the priority.
Pandoc is free software released under the GPL and supports Linux, macOS, self-hosted, web and Windows use; it is an alternative for readers seeking that free-software option.
XnConvert is freeware for private, educational and non-profit use, with a company license priced at 6.50 EUR for 100+ licenses; it is worth considering when that licensing structure fits.
Any Video Converter offers a free download with basic features for macOS and Windows; choose it if a desktop-oriented alternative with a free basic tier is a better fit.
Converseen is free software released under the GNU GPL version 3 for Linux, macOS and Windows; consider it if those platforms and that license suit your needs.
Doxillion Document Converter has a free version limited to non-commercial use and fewer formats for home use; it is an alternative when document conversion and those restrictions fit.

Verdict

Choose MConverter if you need broad format coverage alongside batch and folder handling, cloud file selection or API-based automation. The free plan makes it accessible for light use, and paid tiers offer a clear route to larger files and uncapped daily conversions. Look elsewhere if you need frequent large-file conversions but cannot justify a monthly plan, or if a simple desktop converter would cover your needs without an online workflow.
