Images
Free Online Image Converter
Convert images between JPG, PNG, and WebP.
Supports JPG, PNG, WebP.
Processed on your device
Used for WebP. Lower values usually make smaller files.
What this tool does
Image Converter turns JPG, PNG, and WebP images into a format you choose. It can handle a batch, name each download from the original filename, and pack successful results into a ZIP file.
How to convert images
- Choose the output format. For JPG, set the background color first.
- Add one or more images.
- Download a single result, or download a ZIP if several files succeeded.
Supported formats
- Between JPG, PNG, and WebP, in either direction.
- Up to 20 files, 40 MB each, within the same pixel limits as the resizer: 8,192 pixels per side and 16 megapixels.
Limitations
JPG output always loses transparency. WebP and JPG quality below the maximum is lossy. A failed file does not stop the rest of the batch. This tool does not resize on purpose; dimensions stay the same. Use the Image Resizer for dimensions and the Image Compressor when the goal is a smaller photo.
Privacy
Conversion uses the browser canvas. The ZIP step uses JavaScript already loaded from this site. Image bytes are not sent to a third-party conversion service.
Frequently asked questions
What happens to transparency?
PNG and WebP can keep transparent pixels. JPG cannot. When JPG is selected, transparent areas are filled with the background color chosen before conversion.
Can I convert several images?
Yes. Add up to 20 images. Download each file separately, or download a ZIP when more than one conversion succeeds.
Are HEIC, GIF, and AVIF supported?
No. The converter accepts JPG, PNG, and WebP only. Other files are rejected with an error for that item.
Does converting upload the batch?
No. Each file is read locally. The ZIP is also built in the browser with a local compression library, not by a file-hosting service.
