Conversion keeps the original pixel dimensions. JPEG output uses a white background where the source has transparency.

Note: Animated images are exported as a still image (first frame). Browser support for decoding uncommon formats can vary.

Your image is processed inside your browser and is not uploaded to PixelNest servers. Very large files can use significant memory; for best results, use a current browser and keep the tab open while processing.

Choosing an image format

JPEG is widely supported and often useful for photographs. PNG preserves sharp edges and transparency without lossy compression. WebP supports lossy and lossless compression and is broadly supported by modern browsers.

Will conversion improve quality?

Converting a file does not recover detail that was lost in an earlier export. When converting to JPEG or WebP, a lower quality setting can reduce size but may introduce compression artefacts. Always inspect the preview before downloading.
