Quick answer
Choose a Text contrast tool by three things: local processing, controllable output and clear failures. Insufficient text/background contrast is the most common meme readability problem.
Why it matters
A success/failure-only tool cannot help you isolate the cause.
White text with a black outline works on most backgrounds.
Step by step
- Confirm the use/platform size; don't grab random web images.
- Pick a 1:1 or platform ratio and keep text to 2-3 lines.
- Use a high-contrast outline so it reads on a phone.
- Export PNG and check text/faces/edges.
- Confirm image/likeness rights before publishing.
Common mistakes
- Text too long to read on a phone.
- White text without an outline disappears on bright backgrounds.
- Using unlicensed images/people for commercial content.
- Cropping a watermark/logo and publishing anyway.
Checklist
- Size/ratio match the platform.
- Text is 2-3 lines with a clear outline.
- Image/likeness rights are cleared.
- No watermark/private data.
- Export PNG and spot-check.
