About Image Converter
Image Converter combines the common JPG, PNG and WebP conversion workflows into one focused workspace instead of separate pages for every format pair.
Common use cases
Preserve transparency when needed
Choose PNG or WebP for graphics that need transparent pixels instead of flattening them into a non-transparent JPG.
Balance compatibility and file size
Compare JPG and WebP outputs for photographs, or choose PNG when lossless graphics are more important than compact files.
Create editing-friendly copies
Make a PNG copy for graphics work or a broadly compatible JPG copy for software that does not accept a modern source format.
How it works
1
The browser decodes the selected JPG, PNG or WebP into image pixels.
2
You choose the target format instead of navigating to a separate page for every format pair.
3
For JPG and WebP, the quality control changes the amount of lossy compression used when the new file is encoded.
4
The resulting image is created as a new downloadable file while the original remains unchanged.
Privacy & file handling
Common image conversion stays on your device
JPG, PNG and WebP conversion is performed with browser image APIs. The source image does not need to be uploaded to Zavilo for this workflow.
Limitations and important notes
- Changing the container format cannot restore detail that was already lost through compression, resizing or a low-quality source.
- JPG cannot store transparency, so transparent pixels must be flattened when JPG is selected as the output.
- PNG files can be much larger than JPG or WebP for photographic content because PNG uses lossless compression.
- A smaller file is not guaranteed after every conversion; output size depends on the source image, target format and selected quality.
JPG, PNG and WebP: which output should you choose?
| Feature | Best suited to | Transparency | Typical tradeoff |
|---|---|---|---|
| JPG | Photographs and broad software compatibility | No | Compact photo files, but lossy compression |
| PNG | Logos, screenshots, line art and editing | Yes | Lossless quality, often larger files |
| WebP | Modern websites and mixed photo/graphic use | Yes | Efficient web delivery, but some older software may not accept it |
