Detailed research
Why Users Compare
BeFunky speaks to the same pain that each platform has different size requirements. TextFaker's narrower promise is useful when the platform is known and the question is only whether Instagram's 4:5 feed crop will preserve the subject.
- Display platform target as 4:5 and 1080 x 1350.
- Show original ratio and orientation.
- Show output quality and file size controls only if needed.
Implementation Notes
Tests should separate geometry from rendering. Unit-test crop rectangles in pure functions, then integration-test canvas export with a small generated image.
- Use generated striped test images to detect wrong crop side.
- Verify output aspect ratio equals 0.8 width divided by height.
- Warn when requested export requires upscaling.
Demand Evidence
Creators in public threads describe border workarounds and manual crop practice. That supports a UI that previews both cover-crop and fit-with-padding modes.
Messaging
Avoid saying TextFaker is an open-source app unless project licensing is proven. Say browser-based and open-source-powered when explaining the alternative.
Research notes
- BeFunky's official resizer page says adjusting photos for every online platform is tricky and supports social media resizing with exact dimensions.
- BeFunky has broader photo-editing and design workflows; TextFaker should be positioned as a targeted open-source-powered crop preview.
- The user problem from public discussions is practical: avoid important content being cropped or occluded.
