Image Format Converter

PNG, JPG and WEBP, in any direction, without uploading anything. Drop in one image or a batch, tune quality and watch the output size change live, then download each file or the whole set as a ZIP. Everything runs in your browser.

Drop images here — or paste, or choose files

Multiple files welcome. Files stay on this device; nothing is uploaded.

Warn when a source has EXIF orientation metadata

Downscaling uses the browser's canvas resampler — good, but not LANCZOS-exact, so extreme downscaling can look slightly soft. Aspect ratio is always kept; "max width / height" fits inside the box without upscaling.

Re-encoding through canvas strips EXIF/GPS metadata from every output — that removal is intentional and shown per file.

ZIP is written in this browser: compressed with deflate where CompressionStream is available, store-only otherwise (larger ZIPs on older browsers).
