About AspectDock
Learn how AspectDock builds and reviews privacy-first aspect ratio calculators, image tools, dimension guides, and factual canvas presets for practical use.
Who publishes AspectDock
AspectDock is an independent website that builds and maintains aspect ratio calculators, image tools, and reference guides. You can use every tool without creating an account.
Your images stay private
The image editor works in your browser. Your images are not uploaded to AspectDock, and analytics does not collect filenames, image contents, or the dimensions you enter.
How we build and check the tools
Ratio results come from the formulas shown on the relevant page and are covered by automated tests. Image previews and exports use the same dimensions and fitting rules. Platform presets link to the first-party source used for the listed size.
Keeping information current
A review date shows when we last checked a guide or policy. Third-party platform requirements can change after that date, so check the linked official source before an important export.
