FAQ
Will conversion lose quality?
JPEG is lossy but at default quality 92% the difference is invisible; no extra scaling is applied.
Will the file size change?
It depends on the target codec: JPG/WebP usually shrink files while uncompressed BMP grows significantly.
Is my image uploaded?
No, decoding, encoding and download all run locally in your browser.
