Key Capabilities

Images Stay on Your Device

Decoding and conversion run in your browser. Your photos are never uploaded.

JPEG, PNG and WebP

Convert between any of the three formats and download the result with the matching file extension.

Transparency Handled Honestly

PNG and WebP keep transparency between each other. JPEG cannot, so transparent areas become white, with a warning before you convert.

Same Size, High Quality

The pixel dimensions do not change, and JPEG and WebP are encoded at high quality.

100% Client-Side Processing

When you use Convert Image, your data never leaves your browser. All transformations execute in-memory on your local machine with zero server uploads. Web assets are downloaded to run the tool, but your input data is never transmitted.

Frequently Asked Questions

Is my image uploaded anywhere?

No. Your browser reads, converts, and re-encodes the image on your device. Nothing is sent to YoussefLabs servers. The page does download the code needed to run the tool.

What happens to transparency?

PNG and WebP both support transparency, so it is kept when converting between them. JPEG has no transparency: converting a PNG or WebP to JPEG fills transparent areas with white.

Does the converted image keep its EXIF metadata?

The converted image is re-encoded by the browser and may not retain EXIF metadata such as camera model or location. Photo orientation is applied to the pixels, so phone photos are not rotated incorrectly.

Can I make the file smaller or change its size?

This tool only changes the format. Use Image Compressor to reduce the file size, or Resize Image to change the dimensions. Animated images and GIFs are not supported.
