Overview
Format Factory is a browser-based video and audio converter that handles the most common media format tasks — container changes, audio extraction, and file compression — without requiring a desktop install or an account to get started.
What it does
The service covers four core jobs: converting video between containers (MP4, MOV, MKV, WEBM, AVI, WMV, FLV, OGV, 3GP), converting audio between formats (MP3, WAV, AAC, M4A, FLAC, OGG, AIFF, ALAC, AMR, WMA, OPUS, AC3), extracting MP3 audio from video files, and compressing MP4 or MP3 files by percentage or target size.
Rather than one generic converter, Format Factory offers 20 dedicated tools — each built for a specific format pair or task. There is a focused page for MOV to MP4, another for WAV to MP3, another for MP4 to MP3, and so on. Each page shares the same underlying batch workflow, so switching between tools does not mean learning a different interface.
How the workflow runs
You upload files from your device or paste direct HTTPS links to publicly accessible media. The uploader detects the media type and routes you to the appropriate converter. From there, you select an output format and configure shared settings for the batch — codec, bitrate, resolution, frame rate, trim, crop, subtitles, audio channels, and more, depending on what the selected output supports.
One detail worth noting: the settings form filters out unsupported codec and container combinations rather than accepting them silently. If a setting does not apply to your chosen output, it simply does not appear. This avoids the common frustration of configuring options that the encoder ignores.
Individual files in a batch can keep their own overrides while the rest inherit shared defaults. Each file reports its own progress — upload, queue position, conversion, completion, or error — so a slow or failed item does not obscure what is happening with the rest.
Who it is for
Format Factory suits people who need to convert or compress media files occasionally or in small batches, without maintaining desktop software. That covers a fairly wide range of users.
Content creators frequently need to change container formats — converting iPhone MOV footage to MP4, or preparing video for a platform that does not accept MKV. Podcasters and audio producers use the extraction tools to pull audio tracks from recorded video sessions. Music collectors converting lossless FLAC or ALAC libraries to MP3 for portable players will find the batch audio converter practical. Casual users who need to shrink a large MP4 before attaching it to an email or uploading it to a service with size limits can use the compression tool without learning encoding parameters.
Because it runs entirely in a browser, it works equally on Windows, macOS, Linux, Chromebooks, Android, and iOS. There are no codecs to install and no application to update.
Pricing and access
Free usage starts without an account after a security check. The free tier includes 10 daily credits, a 250 MB per-file limit, and one active job at a time. That covers most single-file conversions and light batch work.
Paid plans raise the per-file limit to up to 12 GB, increase the number of active jobs to as many as 40 simultaneously, and add monthly credits. The Pro plan is the highest tier mentioned. Credit packs are available for users who need occasional larger workloads without committing to a subscription.
The credit system works on a reservation model: the interface shows the minimum credit cost before a job starts, and the final charge is confirmed after processing completes, since heavier encodes can cost more than the minimum. Signing in provides job history, but a paid plan — not login alone — is what raises file size and concurrency limits.
Privacy
Uploaded files are stored temporarily and used only to complete the requested conversion. Format Factory states that uploaded media is not used to train AI models and that personal information is not sold. Files are kept only as long as needed to process, deliver, and expire the result.
