## About

### Convert any image to the right format

Different formats exist for different jobs: WebP and AVIF for lightweight web delivery, PNG for lossless graphics and transparency, JPEG for universally-compatible photos. This converter re-encodes each image on an HTML5 canvas at the quality you choose, so you can switch WebP to JPG, PNG to WebP, or JPG to PNG without installing software or uploading anything.

### Batch, private, and honest about support

Drop a whole folder of images and convert them together, then download each one or all at once. Because encoding runs in your browser, the tool detects which formats your browser can actually produce and disables the rest — so you never get a silently-broken file. Every image is processed locally and never sent to a server.

## FAQ

### How do I convert a WEBP image to JPG for free?

Upload your WEBP file, select JPG as the output format, set your preferred quality level, and click Convert. Download the JPG file instantly — no signup or software needed.

### What is the difference between JPG, PNG, and WEBP?

JPG is best for photos (small files, slight quality loss). PNG is best for graphics needing transparency (larger files, no quality loss). WEBP offers the best of both — smaller files than JPG with optional transparency support.

### Why convert images to WEBP?

WEBP images are 25-34% smaller than JPG at equivalent quality, making websites load faster. Google recommends WEBP for web pages, and all modern browsers support it.

### Can I convert PNG to JPG without losing the image quality?

PNG to JPG conversion always involves some quality change because JPG uses lossy compression. Set the quality slider to 90-95% to minimize visible quality loss while still reducing file size.

### Does converting image formats remove the background transparency?

Converting PNG (transparent) to JPG will fill the transparent areas with white, since JPG doesn't support transparency. To keep transparency, convert to WEBP or keep as PNG.

### Can I convert multiple images at once?

Yes. The batch processing feature lets you upload and convert multiple images simultaneously, saving all converted files at once.

### Does converting to JPG remove transparency?

Yes — JPG has no transparency, so transparent areas become a solid background. Use PNG or WEBP if you need to keep transparency.

### Can I convert several images at once?

Yes — add a batch and convert them all to the chosen format in one go.
