AlphaPNG is a free, privacy-first PNG toolkit that runs entirely in your browser. Compress PNGs by quality or target size, reduce colors, optimize APNGs, resize, crop, trim and convert between PNG, JPG, WebP, AVIF and JFIF without losing the alpha channel. Make transparent PNGs by removing a solid color, or cut out portraits with an on-device AI background remover. Images never leave your device, there is no watermark, and no account is needed. Pro adds 50-file batches, folder uploads and advanced compression.
