AV1 still-frame demonstration — a frame encoded with libaom-av1 · CRF 24 and measured with ffmpeg. AVIF is AV1 intra, so this is the same codec the app uses for video, applied to a still. It is not output from the Make Video Small video pipeline.

Visual Preview Studio
Inspect it before you commit.
Every preset is previewed against the source, with its projected output size, before a single master encode runs.
How it works
Three steps, then it is your machine’s problem.
02
Let it analyse
The engine reads your CPU, GPU and RAM headroom, then proposes a preset that fits the hardware you actually have.
Ultra Quality · Balanced · Max Compression
03
Walk away
The master queue works through every file with live telemetry. Set it to shut the machine down when the last job lands.
Under the hood
Built for people with too many files.
Every core, every shader
Detects NVIDIA, AMD and Intel silicon and routes the encode to whichever path is fastest on your machine. Or force CPU-side SVT-AV1 when you want the smallest possible file and can spare the time.
Nothing leaves the disk
There is no upload step, no account, and no telemetry. Pull the network cable and every feature still works — which is the easiest way to verify the claim rather than take our word for it.
Your PC
Cloud
- No sign-up, no licence key
- No analytics or crash reporting
- No queue, no per-minute billing
- Verified by pulling the network cable
Folder in, folder out
Drop a directory and the master queue works through it unattended.
Live system telemetry
Watch CPU, RAM and GPU headroom while it runs, and throttle it if you need the machine back.
Set it going, then go to bed
Route output anywhere, optionally delete sources once an encode verifies, and shut the machine down when the last job in the queue lands.
Custom output folderAuto-delete sourceShutdown when finishedStealth / Balanced / Beast
No ceiling
No file size limit, no monthly minutes, no queue position. The only constraint is your own disk.
Image Studio & AI Enhancer
It does stills too.
Upscaling, exact-size compression and metadata control, running on your own machine alongside the video engine.
AI upscaling
Real-ESRGAN running on your own GPU. Enlarge up to 4× while recovering detail rather than smearing it.
4× upscale · Vulkan · lossless PNG out
Hit an exact size
A 14-iteration binary search converges on the file size you asked for. Useful when something has to fit under a hard upload limit.
Exact KB target · WebP · AVIF
Metadata studio
Strip GPS coordinates, camera serials and every other EXIF field in one pass, then write back only the fields you actually want to publish.
Privacy guard · metadata injector
Preferences
Tuned to your hardware, not an average one.
Two engines
GPU hardware acceleration when you want it done now, CPU-side SVT-AV1 when you want it as small as it will go.
Decide what it costs you
Stealth keeps the machine usable while it works. Beast Mode takes every core you have. Balanced sits in between.
Finish without you
Custom output routing, optional source deletion after a verified encode, and shutdown when the queue empties.

Comparison
Where it wins, and where it doesn’t.
HandBrake and FFmpeg are genuinely great and cost nothing. This is what changes if you use this instead.

Large because FFmpeg, the Python engine and the upscaling models ship inside it. Nothing is downloaded afterwards.
