Choose a file, check compatibility and create a real downloadable output on your device. No account or file upload is needed.
Static images only. Animated inputs become one frame; multipage TIFF uses the first page. ICO decoding depends on your browser. EXIF, orientation metadata and color profiles are not preserved; canvas decoding may apply orientation. JPEG flattens transparency onto white. PNG/TIFF/BMP ignore quality settings. BMP flattens onto white; TIFF uses uncompressed RGBA. ICO fits the image into 256×256. SVG embeds a raster PNG; it is not vector tracing. GIF uses 256 colors and binary transparency; AVIF uses a local single-thread WASM encoder. Output can be larger than input. SVG resources may be blocked by the browser.
Use a recent desktop browser with WebAssembly, workers, Blob downloads and enough free RAM. File contents stay in this tab; engine/model download requests do not include your files. Browser extensions can have their own access. This tool uses the single-thread engine and does not require cross-origin isolation; a future multithread engine would require COOP/COEP headers and SharedArrayBuffer. Cancel terminates active workers. Clear releases local file references and output URLs.
