Detailed research
Open Alternative Fit
A ratio calculator is a practical open-web alternative to opening a hosted media editor when no export is needed. It answers the source-dimension question first.
Feature Parity And Limits
Kapwing handles image and video resizing. TextFaker should not imply it edits video or produces resized outputs; it only provides the ratio facts used to make those decisions.
Data Control And Pricing
For a single unpublished image, local dimension reading can be preferable to starting a hosted media project. TextFaker still follows the site's shared access rules after free uses.
Where Kapwing Still Wins
Kapwing is stronger when the user needs timeline editing, social-format export, captions, or media conversion alongside resizing.
Practical Migration
Check the image ratio in TextFaker, then use the copied common-ratio match to pick a Kapwing canvas or another editor preset.
Research notes
- Kapwing's official resize page covers media resizing, not only ratio calculation.
- TextFaker should be positioned as a pre-edit fact checker.
- The comparison should mention video only as part of Kapwing's broader scope.
