Key takeaway
JPEG/JPG shines for photos; PNG for sharp UI/transparency; WebP often wins on size with good quality.
Pick by content type, not habit.
What it means
JPEG is lossy photo-friendly.
PNG supports lossless and alpha transparency.
WebP offers lossy/lossless with strong compression; check support needs for very old clients.
When you would use it
Exporting from design tools, optimizing CMS media, building performance budgets.
How to use the tool
Use the matching TCB Tools page and work top to bottom:
- Open Image Converter / Compressor as needed.
- Identify content (photo vs UI).
- Convert/export, then compare size and clarity.
- Keep a master.
No account is required. Results update as you type.
How to choose + examples
Example: photo as JPEG/WebP; logo with transparency as PNG/WebP lossless.
A screenshot with text often looks worse as low-quality JPEG — prefer PNG/WebP.
How to read the result
Smaller is not always better if text blurs.
Test on target devices.
Planning/practical guidance.
Common mistakes
- JPEG for logos with text. Use PNG/WebP.
- PNG for huge photos. Use JPEG/WebP.
- Ignoring transparency needs. Check alpha.
- No fallback plan when required. Know audience browsers.
