How to use this tool

  1. Add PNG files. Drop one image or drag in a whole folder's worth, up to 20 files and 20 MB per file.
  2. Set the quality. The slider starts at 90. Move it down for a smaller JPG or up for more detail. The setting applies to every file in the batch.
  3. Start the conversion. Each PNG is drawn onto a white canvas at its original width and height, then encoded as JPG.
  4. Review the list. Finished files show their new size. Anything that fails is labelled with a short reason instead of leaving you guessing.
  5. Save the output. Use the Download button on any row, or Download all (ZIP) for the complete set.

Why use this tool

Transparent PNGs are wonderful on the web and awkward everywhere else. Print software, older office suites and some upload forms either reject the alpha channel or show it as black. This converter resolves that by filling the transparent areas with white before the JPEG encoder ever sees them, so a logo with a clear background comes out as a clean white card rather than a dark rectangle.

The quality slider gives you direct control over the size-versus-detail trade. A screenshot full of text survives well at 90; a soft photograph can drop to 70 without obvious damage. Because every file is processed on your machine, a batch of scanned documents or product shots does not travel over the internet, and there is no per-file upload delay between images.

Frequently asked questions

What happens to transparent areas?
They become solid white. JPG has no transparency channel, so the tool paints a white background before drawing the PNG on top of it. If you need the transparency, keep the file as PNG instead.
Which quality should I choose?
90 is a sensible default for photos and screenshots. Lower it towards 70 or 80 when file size matters more than fine detail, and keep it above 90 for images with small text. The value is read as each file is processed.
Does the converter keep the original size?
The width and height are unchanged. Only the encoding changes, so the JPG file size depends on the quality you select and on how much detail the picture contains. A flat graphic often compresses far better than a photo.
Can I convert several PNG files at once?
Yes, up to 20 files in one batch. Each finished image can be downloaded on its own, or you can save the whole batch in a ZIP archive that uses a unique name for every file.
