Image Converter — WebP, AVIF, JPEG & PNG
Convert any image to WebP, AVIF, JPEG, or PNG in your browser. Choose the output quality, see the file size before and after, and download the result — no signup, no upload to any server.
Short answer
All conversion happens in your browser. No files are uploaded anywhere. AVIF produces the smallest files but may not be supported by older browsers. PNG is lossless and best for screenshots or images with transparency.
When should you convert an image?
Converting an image format is most useful when you need a smaller file without losing too much quality, or when a specific platform or tool requires a particular format. Moving from PNG to WebP can cut file size dramatically while keeping the image looking nearly the same.
If you are sending images on the web, converting to WebP or AVIF before uploading can speed up page loads. If you need lossless quality for editing, converting to PNG keeps every pixel intact. If the destination only accepts JPEG, a quick conversion handles that without extra steps.
Output format comparison
| Format | Best for | Compression | Why choose it |
|---|---|---|---|
| WebP | Small files, good quality | Lossy & lossless | Best default for web images |
| AVIF | Smallest files at same quality | Lossy & lossless | Best compression, check browser support |
| JPEG | Wide compatibility | Lossy only | Safe choice for photos everywhere |
| PNG | Lossless, supports transparency | Lossless only | Best for screenshots, logos, fine detail |
Which format should you pick?
- WebP is a strong default for web images — good quality at smaller sizes than JPEG, and widely supported in modern browsers.
- AVIF gives you the best compression available today, but older browsers and apps may not open it.
- JPEG is the safest format for maximum compatibility — every device and browser can open it, though it does not support transparency.
- PNG is the right choice when you cannot afford any quality loss or need transparent backgrounds.
- If you are unsure, start with WebP. It usually gives you the best balance of size and quality for most uses.
How to convert an image format
Upload the image
Open the Image Converter and drop or browse for the file you want to convert. JPG, PNG, WebP, AVIF, GIF, and BMP are all supported as input.
Choose the output format
Pick WebP for a good balance of size and quality, AVIF for the smallest files, JPEG for wide compatibility, or PNG for lossless quality.
Adjust quality
For lossy formats like WebP, AVIF, and JPEG, use the quality slider to find the right balance between file size and visual fidelity.
Download the result
Convert the image and download the new file. The tool shows you the before and after size so you can see how much you saved.
Preview before you commit
After converting, the tool shows the before and after file size. If the new file is barely smaller, the original format may already be efficient enough. Try lowering the quality slider a little to find the sweet spot where the image still looks good but the size drops.
FAQ
What image formats can I convert to?
You can convert any image to WebP, AVIF, JPEG, or PNG. Each format has different trade-offs between file size and quality, so the best choice depends on where the image will be used.
When should I use WebP instead of JPEG?
WebP produces smaller files than JPEG at similar quality and supports transparency. Use it for web images where you want faster load times without a big quality trade-off.
Is AVIF better than WebP?
AVIF can produce even smaller files than WebP with good quality, especially at low bitrates. However, AVIF support is not universal in older browsers, so WebP is often the safer default for wide compatibility.
When should I use PNG instead of a lossy format?
Use PNG when you need lossless quality or transparency and cannot afford any compression artifacts. Screenshots, logos, and images with sharp text or fine lines are good candidates.
Is this image converter free and private?
Yes. It is a free browser tool with no signup. Your image is processed on your device and nothing is uploaded to a server.
