What is MyMediaTools?

MyMediaTools is a free online media converter that runs entirely in your web browser. It offers 2,478+ tools to convert, compress, trim, and process video, audio, and image files — without ever uploading them to a server.

Conversions are performed locally using FFmpeg.wasm (the FFmpeg media framework compiled to WebAssembly) and Mediabunny (hardware-accelerated WebCodecs). For every tool, MyMediaTools also displays the exact FFmpeg command used — so you can copy it and run the same conversion on your desktop for files of any size.

Who is it for?
Creators, podcasters, developers, students, journalists, and anyone who needs to convert media without uploading sensitive content to a third party.
What does it cost?
Nothing. There is no signup, no email collection, no watermark, no premium tier on the in-browser tools.
How private is it?
Completely. Your file is read into your browser’s memory and processed locally — no upload, no cloud storage, no telemetry on file contents.
What size files?
Up to ~1 GB in-browser via WebAssembly. For larger files, copy the FFmpeg command shown on any tool page and run it locally — no size limit.

How it works

Three steps. No accounts, no uploads, no waiting in a queue.

  1. Choose your tool

    Search or browse 2,478+ conversion tools organized by format and operation.

  2. Drop your file

    Drag and drop the file onto the tool page. It stays in your browser — nothing is uploaded to any server.

  3. Convert & download

    Click convert, then download. Or copy the displayed FFmpeg command to run the same conversion locally on files of any size.

Why use MyMediaTools?

Built for privacy, speed, and people who actually understand their media stack.

100% private

No upload step. Your file never leaves your device. Verifiable in DevTools — there are no outbound requests for your file content.

Free forever

No signup, no email collection, no paywall, no watermark, no per-day limits. Convert as many files as you want.

Hardware-accelerated

Mediabunny uses your device’s WebCodecs API for native, GPU-backed conversion. FFmpeg.wasm is the fallback for formats WebCodecs doesn’t cover.

Real FFmpeg, exposed

Every tool shows the exact FFmpeg command being run. Copy it to your terminal for scripting, batch jobs, or files larger than 1 GB.

2,478+ tools

Every reasonable format pair across video, audio, and image — convert, compress, trim, extract, resize, mute, rotate.

Works anywhere

Chrome, Edge, Firefox, Safari 16.4+. macOS, Windows, Linux, ChromeOS, iOS, Android. No install, no extension required.

MyMediaTools vs traditional online converters

Most online converters upload your files to a server, queue them, and email or download the result. MyMediaTools does everything in your browser. Here is how that changes the experience:

Feature MyMediaTools Typical online converter
Where files are processed In your browser On a remote server
Upload required No Yes
Privacy Files never leave your device Files stored on third-party servers
Cost Free, unlimited conversions Free tier with caps; paid for more
Signup required No Usually yes
Watermark Never Common on free tier
Speed for small files Instant — no upload wait Bound by upload bandwidth
FFmpeg command shown Yes — copyable on every tool No
File size limit ~1 GB in-browser; unlimited via copied command Hard cap on free tier (often 100 MB)

Who uses MyMediaTools?

From individual creators to teams handling sensitive media, MyMediaTools fits any workflow where files are too private — or too numerous — to upload.

Podcasters

Convert WAV recordings to MP3 or M4A for distribution, trim intros, normalize loudness, extract audio from video interviews.

Video creators

Convert MOV exports to MP4 for upload, compress 4K masters, transcode MKV to WebM, change codecs without re-rendering.

Developers

Grab the exact FFmpeg command for any conversion and drop it into a build script, CI job, or batch processor.

Journalists & lawyers

Handle confidential recordings, depositions, and source material without ever uploading them to a third-party server.

Students & researchers

Convert lecture recordings, interview audio, and dataset media files without account creation or quotas.

Anyone with old media

Convert legacy AVI, WMV, FLV, AIFF, or WMA files into modern formats your phone, browser, or editor can play.

Frequently asked questions

Everything you might want to know about converting media in your browser.

Is MyMediaTools really free?
Yes. Every browser-based conversion tool on MyMediaTools is 100% free with no signup, no watermarks, no ads in the output, and no file-count limits. Files up to about 1 GB are processed entirely in your browser. For larger files, copy the displayed FFmpeg command and run it locally.
Do my files get uploaded to a server?
No. Every conversion runs locally in your browser using WebAssembly (FFmpeg.wasm) or WebCodecs (Mediabunny). Your file never leaves your device — there is no upload step, no cloud storage, and no server-side processing. This is verifiable in your browser DevTools Network tab.
How does browser-based media conversion work?
MyMediaTools compiles FFmpeg to WebAssembly and runs it inside your browser. When you drop a file, the binary data is read into memory, FFmpeg processes it locally, and the output is offered as a download — all without contacting a server. Newer browsers also expose WebCodecs (Mediabunny), which uses hardware-accelerated codecs for faster conversions of supported formats.
What is the file size limit?
Browser memory caps the practical limit at roughly 1 GB for FFmpeg.wasm. Mediabunny uses streaming and has no fixed ceiling. For any file size with no limits, every tool page also displays the exact FFmpeg command you can copy and run locally on macOS, Windows, or Linux.
What formats are supported?
MyMediaTools supports 50 video formats and 21 audio formats including MP4, MOV, MKV, WebM, AVI, WMV, FLV, MP3, WAV, FLAC, AAC, M4A, OGG, and many more. See the full list below for every supported input and output format.
Why does each tool show an FFmpeg command?
The FFmpeg command shown on every tool page is the exact same recipe used by the browser engine — so what you see is what runs. You can copy it and paste it into Terminal (macOS/Linux) or Command Prompt (Windows) to run the same conversion locally on files of any size, or to script batch jobs.
Is MyMediaTools safe for sensitive files?
Yes. Because nothing is uploaded, MyMediaTools is suitable for confidential, NDA-restricted, or regulated content (e.g., medical, legal, financial recordings). Files are processed in an isolated browser tab and discarded when you close it.
Does it work on mobile?
Yes — any modern browser on iOS, Android, macOS, Windows, Linux, or ChromeOS works. Chrome, Edge, Firefox, and Safari (16.4+) are fully supported. Performance scales with device CPU; for very large files we recommend a desktop browser.
How is this different from CloudConvert, Zamzar, or Convertio?
Traditional online converters upload your file to their servers, queue it on shared infrastructure, and email or download the result. MyMediaTools converts entirely in your browser — there is no upload, no queue, no server bill (so it stays free at scale), and no privacy risk. You also get the FFmpeg command for reuse.
Can I use the output commercially?
Yes. MyMediaTools imposes no usage restrictions on files you convert with it. Note that FFmpeg itself is licensed under LGPL/GPL — review FFmpeg licensing for commercial distribution of the binary, but converted output is yours.

About MyMediaTools

MyMediaTools was built by media engineers who were frustrated with uploading sensitive client work to third-party converters. We use the same open-source media stack the entire industry runs on — FFmpeg — and compile it to WebAssembly so it runs in your browser instead of on someone else’s server.

Every tool on this site is generated from a recipe of FFmpeg flags and UI controls. The command you see in the tool page is, byte-for-byte, the command that runs in the browser engine. There is no hidden post-processing, no upselling, no quality reduction. If a setting works on the command line, it works here.

Want to convert files larger than 1 GB, batch hundreds of files, or schedule conversions? Copy the FFmpeg command and run it locally — that is the entire point of showing it. MyMediaTools is for the conversion you want to do right now without thinking about it. The FFmpeg command is for everything else.
