Everything it does.

260 conversions, 16 tools, optional AI models; all of it on your machine, and every job accounted for.

The tools we built in.

OpenConvert is more than a converter. It is meant to replace every web search you have ever run about your own files.

Images

Remove background Cuts the subject out and leaves the rest transparent, matted on your own machine.
needs a model
Upscale Enlarges two or four times over without the softness that usually comes with it.
needs a model
Invert colours Flips every colour to its opposite.
Black and white Drops the colour and keeps the tone.
Compress Makes the file smaller at a quality you choose. The format does not change; only the size does.
Colour picker Reads the exact colour of any pixel, magnified so you can see which one you are taking.
Read text in image Finds the words in a screenshot or a scan and hands them back as text.

PDFs and documents

Extract text
Compress Deflates the streams a producer left uncompressed and drops the document metadata. Nothing is re-encoded, so nothing is lost.
Password Locks the document with AES-256, and an owner password if you want a second one.
Split Breaks one document into several, every so many pages or at ranges you name.
Merge documents Joins documents end to end, hyperlinks intact.
Modify pages Puts the pages in the order you give.
Sign Places a signature image on a page. The receipt records it as a stamped image, because that is what it is.

Audio

Remove background noise Takes the hiss and the room out of a speech recording.

It opens on $0.02, about what a CloudConvert conversion works out at per file. Per-file and per-minute pricing at the hosted tools changes by plan and by month, and background removal or OCR credits cost several times a plain conversion, so treat every rate here as an estimate and pick the one closest to what you actually pay. The only figure this page asserts is its own, and that one is zero.

receipts

Every job leaves a note.

Beside every output is a small file saying what happened to yours. On for every conversion, and switchable off in settings.

What ran: The engine and its exact version: oc-images, libheif 1.17.6
What it did to the file: Lossless, lossy, rebuilt or generated.
What it was allowed to do: The sandbox that actually engaged, and the memory and time limits
What it read: A hash of the exact bytes, so the input can be identified later
What it sent: The number of network calls. It is zero.

How the confinement it records actually works →

A receipt expanded in OpenConvert, listing engine, class, limits, hashes and network calls.
