About Bemiv

Powerful batch image optimisation, lifted out of a Zürich engineering practice. Bemiv was originally a private pipeline that processed hundreds of thousands of marketplace images a week without surprises. The web tool you see is the same code path, exposed at a smaller scale, with the same operational discipline.

Queue worker semantics, exposed in miniature

Each conversion runs in an isolated worker process. Memory contention from one user’s file does not affect another’s work; a single bad image fails on its own and does not starve the queue. The retry policy uses exponential backoff with jitter, capped at five attempts, after which the failure is logged for human review. None of this is exciting; all of it is what makes the tool boringly reliable when other converters become flaky under load.

Determinism by default

Output filenames carry a SHA-256 prefix derived from the source bytes plus the conversion settings. Same source plus same settings produce the same byte stream out, today and tomorrow. The conversion settings round-trip via the download URL, so a customer asking “is this the file we converted on June 12th?” can be answered by inspecting the URL rather than by guessing.

Per-file diagnostics

Failures surface with structured error codes rather than as generic modals. That detail matters when a marketplace ingest job fails on one file in ten thousand and operations needs to know whether the error was an unsupported codec, a malformed colour profile or a broken upload. Bemiv ships those diagnostics as a side effect of its bulk pipeline lineage.

What the public tier looks like

The public Bemiv UI is a single-file web tool. For thousands of files at the same conversion settings, the public UI is the wrong path; talk to us about scripting against the queue worker tier directly. The web converter benefits from the same architecture; bulk customers benefit from the same discipline at scale.

Funding and contracts

The public tier is supported by display advertising. Enterprise queue access is licensed separately and ships with a written agreement under Swiss FADP. We sign DPAs for EU customers, ISDAs for financial customers, and bespoke contracts for marketplace clients with specific audit requirements. The public tier inherits the same retention and privacy guarantees with no additional contract.
