Fourteen tools. One app.

CrownConvert auto-detects every file you drop — video, audio, image, document, or text — and gives you exactly the right controls. No menus to hunt through, no formats to remember.

Convert

Batch any-to-any conversion across video, audio, image and text. Pick a target format per file and hit Convert All.

Pull the audio out of any video, with an optional trimmer and live playback before you save.

Trim Audio

Pro

Trim audio with a simple visual editor and live preview — cut to the exact moment, effortlessly.

Trim Video

Cut a clean sub-clip from any video with start/end frame previews and millisecond precision.

Grab Frame

Scrub a video timeline and save any single frame as a full-resolution PNG, JPG, or WEBP.

GIF Maker

Pro

Turn any video clip into a crisp, great-looking animated GIF, with full control over speed and size.

Your files never leave your machine.

Online converters upload your private documents, photos, and footage to someone else's server. CrownConvert doesn't. Every conversion runs locally on your own CPU — there is no server to upload to, no account to create, nothing to leak.

No uploads

Files are processed in place. No cloud, no queue, no waiting behind other people's jobs.

No accounts

No sign-up, no email required to use it, no telemetry phoning home.

No size limits

Drop a 20 GB video — only your disk decides what fits, not an upload cap.

Offline AI

Even one-click background removal runs entirely on your machine — no downloads, no network, no exceptions.

Simple, honest pricing

Try it free. Own it forever.

Start with the free demo and put the core tools to work. When you're ready, one payment unlocks everything — for life, on your machine, with no subscription and no internet check.

Simple to set up

Install and go

No accounts, no configuration, no learning curve. Run the installer once and every tool is ready — it sets up everything it needs for you, automatically.

Windows 10 & 11

Built for 64-bit Windows. Runs natively as a fast, lightweight desktop app.

One-click setup

A single installer puts CrownConvert on your machine and prepares everything it needs — nothing to configure.

Works fully offline

Once it's set up, CrownConvert needs no internet to run — no online checks, no accounts. Every conversion happens locally on your PC.

Good questions

Frequently asked

Does CrownConvert really work completely offline?

Yes. Every conversion runs locally on your own computer. There is no server to upload to and no account to create. Your files never leave your machine — which also means no upload waits and no file-size limits.

What's the difference between the free demo and Pro?

The demo gives you eight core tools with three full-quality uses each — no watermarks. The six Pro-only tools (Trim Audio, Compress, Vid Compress, GIF Maker, Merge, Remove BG) are locked until you activate. A one-time $29.99 Pro license unlocks all 14 tools forever on that machine.

Is it a subscription?

No. Pro is a single one-time payment with no recurring charges, ever. Your license is tied to your machine and survives software updates. Because it's hardware-locked, a major hardware change — such as a new motherboard or drive — may require re-activating it on the new setup.

Will it slow down or watermark my files?

Never. Demo output is full quality with no watermarks of any kind. CrownConvert is tuned for clean, high-quality results out of the box, and converts your files quickly — even in large batches.
