1. Upload your image

Click Select Image(s), drag and drop, or paste (Ctrl/Cmd+V). Supported formats include JPG, PNG, WebP, AVIF, GIF, SVG, and HEIC/HEIF. You can select multiple files for batch work.

2. Choose dimensions or a preset

Enter width and height, or pick a social preset (Instagram, YouTube, TikTok, profile picture, and more). Keep aspect ratio locked unless you intentionally want to stretch the image.

3. Crop (optional)

Open the Crop tab, choose freeform or a ratio like 1:1 or 9:16, adjust the handles, then Apply Crop.

4. Convert format

Use Convert Image Format for JPG, PNG, WebP, or AVIF. WebP and AVIF often produce smaller files than JPG at similar visual quality. Animated GIFs export as a single frame.

5. Compress & download

On the Compression tab, lower quality for smaller files (JPG/WebP/AVIF). Preview the estimated size, then download one image or process a batch as a ZIP.
