Editorial Policy
How we make every guide.
This page explains, in plain language, how Alpha Image Premium researches, reviews, tests, updates and fact-checks the tools and guides you rely on.
Maintained by the Alpha Image Editorial Team · Last updated November 2026
How articles are researched
Every guide begins with a scoped research brief. Our editors review the current state of the technique across authoritative sources — browser vendor documentation (MDN, Chrome, WebKit), IETF and W3C specifications, published academic papers on image processing, and hands-on testing across real workflows. When we cite numbers (compression savings, file sizes, browser support), those numbers are measured on our own reference dataset — never copy-pasted from other sites.
How content is reviewed
Draft articles go through a two-stage review. The first pass is a technical review by a subject-matter engineer or designer who reproduces every step in the guide from scratch. The second pass is an editorial review focused on clarity, accessibility, structure and reading level. Only after both reviewers sign off is an article published. Every published article carries a Verified Author badge and, where applicable, the reviewer's name in the changelog.
How tools are tested
Every tool on Alpha Image Premium is tested against a fixed regression suite of 100+ sample images spanning photography, screenshots, transparent PNGs, huge canvases, and edge-case formats. We test in the latest stable Chrome, Safari, Firefox and Edge on desktop and mobile before every release. If a tool cannot produce a lossless-quality result on the same input as a well-known desktop editor, it does not ship.
Update policy
Guides that reference platform sizes (Instagram, YouTube, TikTok) or format support tables are reviewed on a quarterly cadence. Everything else is reviewed at least once a year. When we substantively update an article, the 'Last updated' date and version number both change, and the old version is preserved in our internal changelog for auditability.
Fact-checking policy
Every factual claim in an article is traceable to a primary source (a spec, a vendor doc, a first-party benchmark, or an in-house test). If we discover a factual error after publication, we correct it within 48 hours and add a dated correction note at the bottom of the article. If a correction changes the practical recommendation, we notify readers who linked to it whenever we have the ability to do so.
Editorial independence
We are not paid to feature, recommend or rank third-party products, formats or platforms. When a guide mentions an external tool it is because it is genuinely the best fit for the reader's task. Any commercial relationship (sponsorship, affiliate) will always be disclosed clearly at the top of the article — and we currently have none.
