The last file appyou'll ever download.
A complete file toolkit that runs entirely on your own machine. Eighteen instruments — to convert, caption, read, compress and restore — in one quiet application that never asks you to upload a thing.

yours for good
Your files are nobody else's business.
Every day, people hand private footage, scanned contracts and personal photographs to free websites simply to change a file extension — surrendering them to servers they will never see, then waiting in a queue for the privilege. CrownConvert does the same work on the machine already sitting in front of you.
Eighteen tools,
one window.
CrownConvert recognises whatever you drop into it — video, audio, image, PDF, document or plain text — and offers only the controls that make sense.
Convert
Batch any-to-any conversion across video, audio, image and text. Choose a target format for each file, then let the whole queue run at once.
Documents
Word to PDF, PowerPoint to PDF, and back again — with ODT, ODP and RTF besides. Your originals are never altered.
Extract Audio
Lift the sound out of any video, with a visual trimmer and live playback before you commit to saving.
Subtitles
Drop in a recording and receive accurate captions — as subtitle files, or burned into the picture. Fifteen languages, transcribed on your own machine.
Trim Audio
Trim on a visual waveform. Draw the handles, hear the selection, cut to the exact moment.
Trim Video
Take a clean sub-clip from any video, with start and end frames previewed and millisecond precision.
Grab Frame
Scrub a timeline and keep any single frame at full resolution, as PNG, JPG or WEBP.
GIF Maker
Turn a clip into a crisp animated GIF, with speed, width and length entirely in your hands.
Merge
Join several videos or recordings into one. Drag to order them, then let it stitch them together cleanly.
PDF Arrange
Set several PDFs side by side and draw pages between them until the document reads the way you intended. The sources stay untouched.
PDF Split
Break one document into many — by page range, by every few pages, by odd and even, or one file per page.
OCR
Turn scans and photographed pages into documents you can select and search — or lift the words out as plain text.
Compress
Bring images and PDFs down to a target size, keeping the largest, sharpest version that still fits.
Vid Compress
Reduce a video to an exact size while keeping the picture sharp and the motion smooth.
Resize
Resize images in batches to any dimensions, with aspect ratio held and edges kept clean.
Upscale
Genuine AI super-resolution at two, three or four times — rebuilding detail rather than stretching pixels. Quicker with a graphics card, content without one.
Metadata
Strip the location, GPS and camera data hidden inside your photographs before they leave your hands.
Remove BG
Lift the subject out of any photograph in a single click, as a clean transparent PNG. Three levels of quality, up to flawless around hair.
One purchase
ends five bills.
CrownConvert is not merely a converter. Several of its instruments are, on their own, a subscription somebody is paying for this month.
| Inside CrownConvert | What it costs elsewhere |
|---|---|
| PDF arrange, split, merge, convert & OCR to searchable PDF | Adobe Acrobat Pro $20/mo · Smallpdf $9–12/mo |
| Automatic subtitles, transcribed offline | Otter, Descript & online transcription $12–24/mo |
| AI background removal | remove.bg $9/mo, or credits per image |
| AI image upscaling | Topaz Gigapixel $99 · subscription upscalers |
| Compress, resize, trim, GIF & metadata | A scattering of freemium tools with upload ceilings |
Acrobat, a background remover, a transcription service and an upscaler — retired by one application, bought once. Somewhere near $40–60 a month, gone.
It reads almost
anything you own.
The input list is deliberately generous — 60+ video, 55+ audio and 50+ image formats, with Word, PowerPoint and PDF besides. What comes out is a considered set of the formats you actually wanted. Below are examples, not the full inventory.
Nothing leaves
this machine.
The work happens on your own hardware. CrownConvert speaks to us about your account and your licence, or to collect an optional model once. It never speaks to us about your files.
No uploads
Files are handled where they already sit. No cloud, no queue, no waiting behind somebody else's job.
You are not the product
There is an account, and it holds your licence. It never learns what you opened, converted or created.
No ceiling
Give it a twenty-gigabyte film. Only the disk decides what fits — never an upload limit.
Intelligence, offline
Upscaling, background removal, captioning and OCR — the work usually kept behind a paywall — all of it runs here.
Install once,
then forget it.
No configuration and no learning curve. Run the installer and every instrument is ready — it arranges whatever it needs on its own.
One price.
Yours for good.
No subscription, no tiers, no upsell. A single payment opens all eighteen instruments for life. Less than one month of what it replaces.

Questions
you might have
Is it genuinely offline? Do my files go anywhere?
Your files never leave the machine. There is no server to send them to, which is also why there is no upload wait and no size limit. CrownConvert goes online to verify your account and licence and, should you choose a premium model, to collect it once. Nothing about the files you process is ever sent, logged, or seen by us.
What formats does it handle?
Essentially anything in common circulation — 60+ video, 55+ audio and 50+ image formats, alongside Word, PowerPoint and PDF. What it writes back is a considered set of useful targets, so you are never left guessing which to choose.
Do I need a powerful graphics card?
No. Upscaling will use a card if one is present — any make, including the one built into a laptop — and falls back to a simpler method if not. Background removal, captioning and OCR run on the processor.
Speed, though, does follow your hardware, and it would be dishonest to pretend otherwise. CrownConvert runs several jobs at once and lets you choose how many; on a machine with four cores or fewer it runs fewer at a time and tells you plainly when an operation is likely to be slow. The highest background-removal setting also expects a capable machine. Nothing is locked away or degraded — a large batch simply takes longer on a modest computer than on a fast one.
Does it check my licence online?
Occasionally, and never with your files attached. You activate once while connected; after that CrownConvert works offline for weeks at a stretch, re-checking quietly whenever you happen to be online. Travelling, in the air, or simply disconnected — it keeps working throughout.
Is it a subscription?
No. CrownConvert is $49 as a single payment, currently $30 as a launch discount. There are no recurring charges, and lifetime updates across version two are included. Upgrading parts of your machine — a drive, a card, more memory — will not break your licence.
Will it slow down or watermark my files?
Never. There are no watermarks of any kind, no export ceilings and no throttling — you own it, so everything runs at full quality. CrownConvert is tuned for clean results out of the box and moves quickly, even through large batches.
How do I begin after buying?
A licence key arrives at checkout, alongside the download. Install CrownConvert, open it, and paste the key when it asks — the only time you will need to. From then on it opens straight into your instruments.
