What this site will and will not claim.
This page explains how the guides, comparisons and tool documentation are written, what gets checked, and how corrections work. It is deliberately short enough to read before trusting a number.
The short version
- Every factual claim should point to a source you can open, or to a test described on this site.
- Competitor limits are dated. If two official pages disagree, the article says so instead of picking one silently.
- No paid rankings, no affiliate links, no “best” label without a published criterion.
- No invented tests, quotes, customer stories or user counts.
- If a claim changes, the page's updated date changes with it.
What we publish
Three kinds of pages: tool documentation (what the converter does and where it fails), guides (one format or workflow question), and comparisons (a shortlist of tools for a named job). The comparisons include this site when it is one of the options, and say so at the top of the article.
How facts are checked
Product limits, file-size caps and pricing come from the vendor's own pages — pricing, help centre, terms or size-limits pages — not from a roundup that may be out of date. The date of the check is visible in the article and in the source list. When a vendor's own pages conflict, both numbers are reported and the reader is told to plan for the stricter one.
Technical claims about codecs, sample rates and file sizes are checked against format documentation or a local test. If a number cannot be traced to either, it is removed rather than estimated into the text.
How the converter is tested
The engine is exercised against fixed fixtures on every change: MP4/AAC, MOV/AAC, MOV/ProRes with PCM, M4A/AAC, M4A/ALAC (which must fail), WAV 16-bit, WAV 24-bit/96 kHz, MP3, a silent MP4, a truncated MP4, a 5.1 source, a MOV with two audio tracks, and a trimmed file. Outputs are checked with ffprobe for codec, duration, sample rate and channel count. The browser matrix covers Chromium, Firefox and WebKit. The how-it-works page describes the same limits in user terms.
What we do not do
- We do not sell placements or rank a tool because of a commercial relationship.
- We do not use affiliate links in comparisons.
- We do not give star ratings without a public rubric that a reader could reproduce.
- We do not claim a competitor failed a test we did not run.
- We do not help remove DRM or convert content the user has no right to use.
- We do not call a conversion “lossless” when the output is a lossy format.
Corrections and updates
Each guide and comparison carries an updated date. A correction changes that date and the JSON-LD
dateModified value with it. Competitor limits are rechecked when the article is revised; they
are not continuously monitored, so a page can be older than the vendor's latest change. The source list is
the first place to check before relying on a cap.
Authorship and automation
This site is maintained by an independent publisher that builds single-purpose browser tools. There is no invented author biography, no stock “audio expert” persona and no fake review panel. Drafting is assisted by software; the factual claims, limits and test results are checked against the linked sources. No test result, quotation or customer story is generated.
Contact
A contact address is being set up. Until it is published, corrections are recorded as dated revisions on the page that changed, and the about page describes the site's scope.
