Direct answer
To use image-resizer, start with a small representative input, change dimensions while preserving an intentional aspect ratio, and inspect the result before relying on it.
Key takeaways
- Purpose: change dimensions while preserving an intentional aspect ratio.
- Check: pixel dimensions, aspect ratio, transparency, edges and visual artifacts.
- Limitation: lossy formats may introduce halos and some formats cannot preserve transparency.
Common mistakes
- Assuming the output is correct because the operation completed. Instead, inspect pixel dimensions, aspect ratio, transparency, edges and visual artifacts.
- Using production or confidential material as the first test. Use a 2400 by 1600 pixel product photo instead.
- Ignoring compatibility: lossy formats may introduce halos and some formats cannot preserve transparency.
