Key points about image format conversion

output format: PNG (lossless) · JPG (lossy) · WEBP (high compression) · BMP (uncompressed) · GIF (animation)

Formats trade off size and quality: PNG suits transparency and crisp graphics; JPG suits photos; WEBP is smaller at similar quality; BMP is raw uncompressed; GIF supports simple animation.

The tool decodes and re-encodes locally with no upload, ideal for batch organizing assets, unifying website resources, and reducing load size.

Frequently asked questions

Does conversion lose quality?

JPG/WEBP are lossy and may lose a little; PNG/BMP are lossless and keep all detail.

Can it convert in bulk?

Yes, select many images at once and output a uniform target format.

Does it need internet?

No. All encoding runs locally in the browser; images are never uploaded.
