Frequently asked questions
Which format should I choose?
WebP for the web — it's the smallest at great quality and supports transparency. JPG for maximum compatibility with older software. PNG when you need lossless quality or transparency.
Does converting to JPG remove transparency?
Yes — JPG has no transparency, so transparent areas are filled with white. Use WebP or PNG if you need to keep transparency.
Are my images uploaded?
No. Conversion happens in your browser with the Canvas API; your files never leave your device.
How this tool helps
A project may require one image format even though your source files use another. Use WebP for modern websites, JPG for compatibility, and PNG when lossless detail or transparency matters.
How to use it
- Add the source images.
- Select the output format and quality.
- Check the previews, then download the converted files or ZIP.
Example
Convert a folder of PNG screenshots to WebP before adding them to a documentation site.
What you get
The tool preserves dimensions and creates a new file in the selected format; the source file is unchanged.
Good to know
Limitations: JPG cannot preserve transparency. Quality settings affect file size and visible detail, especially in photographs.
Privacy: Conversion uses the browser Canvas API and does not upload your files.
How PixelTools makes this decision
PixelTools shows the settings and the result side by side so you can make an informed choice before downloading. File size is measured from the actual browser-generated output, while dimensions, format, and visual preview are kept visible because a smaller file is not automatically a better file. The original is never overwritten.
These tools are maintained as practical, browser-first utilities rather than upload forms. We document the trade-offs for each task, test the output in the browser, and link to related guides when a different format or workflow may be a better fit. For troubleshooting, see Help & Support; for the full data-handling explanation, read the Privacy Policy.
