COMPRESS • Adjust JPEG quality with a simple slider to balance size and clarity • Set a target file size in KB and let the app find the optimal quality for you • Choose whether to preserve or remove EXIF metadata CONVERT • Convert images to JPEG for smaller file sizes with lossy compression • Convert images to PNG for lossless quality with transparency support • Extract all frames from a GIF and save them as individual PNG images EDIT • Adjust — fine-tune brightness, contrast, saturation, and sharpness • Transform — rotate by 90° or 180°, flip horizontally or vertically • Crop — trim edges with pixel-level precision • Resize — set a custom width and height in pixels All image processing is performed locally using on-device APIs. The app works fully offline and never sends your photos anywhere.
