Convert Images Between PNG, JPEG, WebP, and AVIF Formats

An upload form rejects your PNG, a website needs a smaller WebP, or a client insists on a plain JPEG for an email attachment. The Image Converter changes a picture between PNG, JPEG, WebP, and AVIF without a graphics program or a command line. You keep the same pixels and simply swap the container and compression, which is exactly what you need when compatibility or file size decides the format. The conversion runs entirely in the browser, so your image never leaves your device.

How to Convert an Image to a New Format

  1. Open the Image Converter and drop your image into the upload area, or browse for it on your device.
  2. Choose the target format: PNG for lossless, JPEG for photos, WebP for the web, or AVIF for the smallest files.
  3. Adjust the quality slider if the target format supports compression, such as 85 for a good JPEG balance.
  4. Click convert and let the tool re-encode the image in place.
  5. Preview the result and download the converted file, or convert another image from the same screen.

Real Example: Shrinking a PNG Screenshot for a Blog

A 1.4 MB PNG screenshot is too heavy for a blog post. Converting it to WebP at quality 80 drops it to roughly 180 KB with no visible difference on screen, and the browser still renders it perfectly. When the content management system later demands a JPEG fallback, the same tool produces one in a second pass.

Tips for Choosing the Right Output Format

When You Need an Image Format Conversion

Frequently Asked Questions

Which formats can I convert between?

The converter supports PNG, JPEG, WebP, and AVIF in both directions. Every combination among the four formats is available from the target format dropdown.

Does converting to JPEG remove transparency?

Yes. JPEG has no alpha channel, so transparent areas are flattened onto a background color during conversion. Use PNG or WebP when you need to keep transparency.

What does the quality slider control?

The slider sets the compression level for lossy formats such as JPEG, WebP, and AVIF. Lower values give smaller files with more visible artifacts; higher values preserve detail at a larger size.

Is AVIF supported by all browsers?

No. AVIF works in current Chrome, Firefox, Safari, and Edge, but older browsers cannot display it. Ship a WebP or JPEG fallback when your audience may use outdated software.

Will conversion change the dimensions of my image?

No. Converting changes only the encoding and container. The pixel width and height stay identical, so you never need to re-crop or re-place the image afterwards.

Are my images uploaded to a server?

No. The conversion runs entirely in your browser, so the image file never leaves your device. This makes the tool safe for sensitive screenshots and documents.

Can I convert several images at once?

The tool handles one image per conversion for precise control over format and quality. For batch work, convert the same file to multiple formats in quick succession.

Why is my converted file larger than the original?

A lossless PNG converted to a high-quality JPEG or WebP can grow, especially for graphics with flat colors. Lower the quality slider or pick AVIF to shrink the output.
