How to use
- All conversion happens in your browser — images are never uploaded, so you can safely process private photos.
- JPG / BMP do not support transparency; images with transparent areas get a white background. Use PNG / WebP / AVIF to keep transparency.
- HEIC (iPhone photos) and TIFF cannot be previewed directly by the browser, so the tool decodes them first to make a thumbnail — adding them is a bit slower.
- AVIF has the highest compression but encodes slowly; please be patient when batch-converting large images.
