Image

Convert, compress, resize and inspect images without installing an editor or uploading anything — files are read locally by your browser using the canvas API. Turn a PNG into WebP, shrink a photo below an upload limit, crop to an exact ratio, view or strip EXIF metadata, or generate favicons and QR codes. Because nothing is uploaded, these tools also suit screenshots and documents you'd rather keep private.
