PNG · 30 MB per file · Up to 20 files

Original files stay unchanged. Downloads contain re-encoded images, not an archive of the originals. Open-source processing libraries.

HOW THIS TOOL WORKS

Choose up to 20 PNG images, review the output settings and click Process images. The tool checks file contents, converts images locally and verifies the exported format and dimensions. Download one JPG image or a ZIP of completed results.

What this PNG to JPG converter preserves

JPEG does not support transparency. Choose a background colour before processing. JPEG uses lossy compression, so conversion cannot be described as lossless. Small PNG graphics can become larger as JPEG.

How to convert PNG to JPG online

This converter handles the complete PNG to JPG workflow on one page, including multiple files. It does not require a desktop extension or an account.

  1. Choose original PNG files or drag them into the tool.
  2. Choose JPEG quality and the background colour used for transparent pixels.
  3. Start processing. Each image shows its own completion or error message.
  4. Compare Original and Output, then download a file or the completed batch as a ZIP.

PNG to JPG: quality and file size

JPEG does not support transparency. Choose a background colour before processing. JPEG uses lossy compression, so conversion cannot be described as lossless. Small PNG graphics can become larger as JPEG.

The preview represents browser-rendered images. Keep your originals for archival storage and colour-critical work. The tool does not promise a smaller file or recover detail that was missing in the source.

Batch convert PNG files without uploading

Files are processed sequentially in a separate Web Worker so the page stays responsive. Cancel stops the current worker and keeps completed downloads. A file that fails does not stop the rest of the batch.

Downloads remain available while this page is open. Clear all files to release their previews and results. Large batches can exceed mobile browser memory, so use fewer files if your browser stops processing.

Frequently asked questions

01Is this PNG to JPG converter free?+

Yes. There is no sign-up, watermark or payment step. The displayed file size, image dimension and batch limits apply.

02What happens to transparent PNG backgrounds?+

Transparent areas are flattened onto the background colour you choose. White is the default. Check the output preview before downloading, especially around semi-transparent edges and logos.

03Are my images uploaded to a server?+

No. The page downloads its processing code, then reads and converts your chosen images locally. ZIP archives are also created on your device.

04Can I batch convert PNG files?+

Yes. Add up to 20 images within the 80 MB input limit. Process the queue, then download files separately or use the ZIP button. The total generated output is limited to 120 MB.

05Why did one of my files fail?+

The tool checks actual file contents rather than trusting extensions. A mismatched format, corrupt file, animated image, unsupported HEIC variant or image over the resource limits produces a per-file error. Completed files remain downloadable.
