Editorial Policy

How guides are prepared

Guides are organized around real tasks such as exact dimensions, target bytes, email, print, product photos, transparency, mobile memory, and privacy.

Use of official sources

Platform specifications and browser behavior that can change are checked against official documentation when available. Unverified numbers are not presented as guarantees.

Review and update dates

Each guide shows a review date and explains the limits that remain relevant. A date does not mean every third-party platform will keep the same specification.

• Keep the original file before editing.
• Check dimensions, crop, transparency, and file size after download.
• Do not send private source images when reporting a problem.

Translation review

Localized pages are written for the search language rather than produced by swapping a few keywords. Technical format names remain where they are necessary for accuracy.

Advertising separation

Advertising is visually and structurally separated from upload, processing, and download controls. Payment or ad interaction is not required to finish an edit.

Corrections

Corrections should replace inaccurate instructions, update the review date when the substance changes, and preserve a clear distinction between tests, estimates, and official rules.
