WebP, JPG and PNG: choose by output needs
Choose an image format by transparency, edit history, receiving-system support and measured output size.
Format trade-offs
PNG provides lossless raster compression and supports transparency. JPG uses lossy compression and has no alpha channel. WebP supports lossy and lossless variants and transparency. Actual file size depends on the image and encoder settings.
A reproducible comparison
- Start from the same source image.
- Use a matching Tooldit converter to export candidate formats without resizing.
- Record dimensions and bytes, then inspect edges, gradients and text at the same zoom.

Avoid unsupported promises
Do not assume one format is always smaller or that re-encoding repairs lost detail. Test the destination application and retain a high-quality original. Animated inputs can become a still frame in these converters.
Privacy and output checks
Tooldit file and text tools process their contents locally. Optional page analytics is separate, and SEO and contact tools use network services. Read the Privacy Policy. Keep original files and inspect the output before sharing it. Examples in this guide are instructions, not measured performance tests.
