Use cases

  • Converting PNG screenshots to JPEG for smaller file sizes
  • Converting a photo library to WebP for better web performance
  • Converting WebP images to PNG for compatibility with older software
  • Preparing images in a specific format required by a CMS or platform

Frequently asked questions

Should I use WebP, JPEG, or PNG?

WebP is the best choice for web — it's smaller than JPEG at the same quality and supports transparency like PNG. Use JPEG for broad compatibility, and PNG for images requiring lossless quality or transparency on legacy systems.

Will converting PNG to JPEG lose the transparency?

Yes — JPEG doesn't support transparency. Transparent areas will be filled with white (or a custom color if you use the Flatten Transparency operation first). Use WebP if you need both small file size and transparency.

Does converting change image dimensions?

No. Format conversion only changes the file encoding, not the dimensions. Add a Resize operation alongside Convert if you want to change dimensions too.

Can I convert TIFF or AVIF files?

PixelForge can read TIFF and AVIF files, but output is limited to JPEG, PNG, and WebP. This covers the vast majority of web and design use cases.
