How to convert images online
- 1
Upload your image
Choose one image or a small batch from your device, or drag the files into the converter. Common formats like JPG, PNG, WebP, and AVIF are supported.
- 2
Choose the new image format
Pick the output format you need, then adjust quality if the format supports lossy compression. This is useful when you want a smaller file, better compatibility, or a format that preserves transparency.
- 3
Convert and download
Run the conversion and download the new image files when they are ready. The process happens in your browser, so you can convert image files online without sending them to a remote server.
Understanding the settings
JPEG is usually the safest choice for photos when you want broad compatibility and smaller files. PNG is better for screenshots, graphics, and images that need transparency. WebP is a strong modern format for websites because it often keeps good quality at a smaller size, while AVIF can be even more efficient when your target workflow supports it. If the source already contains compression artefacts, converting it to a lossless format will not restore the missing detail.
Best settings for common goals
Format comparison
| Format | Best for | File size | Quality |
|---|---|---|---|
| JPEG | Photos and broad compatibility | Small | Lossy |
| PNG | Screenshots, graphics, and transparency | Large | Lossless |
| WebP | Website images and modern delivery | Small | Efficient lossy or lossless |
| AVIF | Next-generation web optimization | Very small | High efficiency |
Practical guidance
Compatibility, privacy, and limitations
Things to keep in mind
- Converting a lossy source into a lossless format does not restore detail that was already lost in the original image.
- Newer formats like AVIF can be more efficient, but some older software and workflows still behave more predictably with JPEG or PNG.
