About Format Factory

Format Factory is an online video and audio converter for common media jobs. It changes video containers, converts audio, extracts an MP3 from video, and compresses MP4 or MP3 files. The homepage is the starting point, while each conversion page focuses on one format pair or task. Use a general converter when you want to choose among several outputs, or open a focused page when you already know the result, such as MOV to MP4 or WAV to MP3.

You choose files in the browser and cloud workers perform the media processing. This keeps the workflow available on Windows, macOS, Linux, Chromebooks, phones, and tablets without asking you to install codecs or maintain another desktop program.

How Format Factory converts media online

The path stays the same across the homepage and the focused conversion pages. You provide the media, choose the result, and run the queue. Available controls change to match the selected output.

  1. Add the files

    Choose one or more video or audio files from your device. The uploader checks the media type before it sends you to the matching converter.

  2. Choose the result

    Select an output format and start with the shared settings for the batch. Open a file's settings when it needs a different codec, size, trim, crop, subtitle, or audio setup.

  3. Convert and download

    Start the queue and follow each file separately as it uploads and converts. A finished file can be downloaded as soon as it is ready, even while the rest of the batch is still running.

Format Factory supported video and audio formats

The converter accepts the containers and codecs commonly produced by phones, cameras, screen recorders, editing software, music apps, and older media libraries. Each converter only shows the outputs supported by its media type and task.

Format Factory quality and file-size controls

Default settings give most files a practical starting point, but you can also open the CPU options supported by the selected output. Video controls can include codec, quality or bitrate, encoding speed, resize, frame rate, subtitles, audio, effects, trim, and crop.

Audio settings can include codec-specific quality or bitrate, sample rate, channels, volume, effects, and trim. Some choices only work with certain containers or codecs. The form filters unsupported combinations rather than accepting a setting and quietly producing a different result.

Shared settings can apply to all compatible files, while one file can keep an override. Compression by percentage or target size remains an estimate because the source and encoder affect the final size.

Why Format Factory works for batch media

Media conversion becomes repetitive when several files need the same result. The interface keeps shared settings together, reports each file separately, and lets one item keep an override without forcing a new batch.

Batch-ready controls

New files inherit the shared output and settings. Apply a change to the whole batch or keep a specific override on one file.

A browser-based workspace

The interface works in a modern browser, while cloud workers run the media processing. There is no desktop installer to maintain.

Progress for every file

Each item reports its own upload, queue, conversion, completion, or error state, so one slow file does not hide the rest.

Settings that match the output

The form shows only the controls supported by the selected container and codec instead of accepting options the final file cannot use.

Privacy and temporary file handling

Uploaded media is sent to the services needed to store the file temporarily and complete the requested conversion. Files and outputs remain available only as long as needed to process, deliver, troubleshoot, and expire the result. The service does not use uploaded media to train AI models and does not sell personal information.

Upload only media that you have the right to process. Account, payment, job, and analytics data is handled separately from the media. Read the privacy policy for details about data handling and service providers.

Format Factory plans and usage limits

Free usage starts with 10 daily credits, files up to 250 MB, and one active job at a time. Paid plans add monthly credits and raise the per-file and active-job limits. The Pro plan supports files up to 12 GB and as many as 40 active jobs.

Before a job starts, the interface shows the credit balance and minimum reservation. Processing-heavy jobs can cost more, so the final charge appears after completion. Credit packs cover occasional larger workloads without a subscription.

Format Factory common questions

What is Format Factory?

Format Factory is an online video and audio converter for changing media formats, extracting MP3 audio from video, and compressing MP4 or MP3 files. You manage the job in a browser and cloud workers process the media.

Do I need to install anything?

No. The converter works through a modern web browser, so there is no desktop application or local codec package to install. Choose files, select the result, and manage the conversion online.

Do I need an account to convert a file?

You can start without signing in after the required security check. Signing in gives you account-based job history. Paid plans, rather than login alone, raise file and active-job limits.

How many files can I convert at once?

A video, audio, extraction, or compression batch can contain up to 50 compatible files. The batch shares one output format and defaults, while individual files can keep advanced setting overrides.

Which video and audio formats are supported?

Video inputs include MP4, MOV, MKV, WEBM, AVI, WMV, FLV, OGV, and 3GP. Audio inputs include MP3, WAV, AAC, AIFF, ALAC, AMR, M4A, OGG, FLAC, WMA, OPUS, and AC3. Outputs depend on the converter.

Can I control output quality and file size?

Yes. Depending on the output, settings can include CPU codec, quality or bitrate, resize, frame rate, audio options, subtitles, effects, trim, and crop. Unsupported combinations are hidden instead of silently replaced.

How much does it cost?

Free usage includes 10 daily credits and a 250 MB limit per file. A job reserves a minimum before it starts and reports the actual processing charge after completion. Subscriptions add monthly credits and raise file and active-job limits.

What happens to uploaded files after conversion?

Uploaded media is used to run the conversion you requested. Files and outputs are kept only as long as needed to process, deliver, troubleshoot, and expire results. Uploaded media is not used to train AI models, and personal information is not sold. Read the privacy policy for more detail.
