Editorial policy
Useful by default. Verifiable by design.
Ownership
Independent publishing with a named author.
Author
ImageBig is written and maintained by Yang Maojuan Dàshū, an independent software developer and project builder based in China. Author attribution is shown on editorial and tool pages.
Independence
ImageBig is not affiliated with Etsy, Canva, Bigjpg, Upscayl, Adobe, or the printer or marketplace providers mentioned on the site. Product names are used only to describe workflows and comparisons.
Commercial disclosure
ImageBig currently offers a free browser preview without an account. If a future page contains a sponsorship, affiliate relationship, paid placement, or other material commercial relationship, the relationship should be disclosed on that page.
Sources
Separate standards, calculations, and provider rules.
Primary sources first
Technical claims should link to the relevant standard, research paper, official documentation, or provider help center. When no universal standard exists, the page should say so and identify the printer, marketplace, or provider requirements as the authority.
Calculations are not guarantees
Pixel and DPI calculations describe mathematical outcomes. They do not certify sharpness, color, bleed, accepted file formats, marketplace approval, or production readiness.
Verification dates
Editorial pages show a publication and last-reviewed date. A date is changed only after the relevant sources, calculations, links, and limitations have been checked. Provider-specific requirements should be rechecked before production.
AI assistance
Automation can help draft; it cannot supply evidence.
ImageBig may use automated tooling for drafting, code validation, formatting, and consistency checks. Generated text is not treated as a source, real expert, customer, test result, or third-party endorsement.
Corrections
Report incorrect facts, broken links, unclear limitations, or misleading claims through the Contact page. Corrections are reviewed against the page URL, visible evidence, and available primary sources.
What is not published
ImageBig does not intentionally publish fabricated reviews, invented statistics, fake authors, undisclosed paid rankings, or claims that a free preview is a verified production file.
