Image Compressor
Resize and compress images locally. Your files never leave your device.
Shrink image file sizes for faster websites, email attachments, or social posts. Adjust quality and max width, then download a compressed copy. Unlike cloud compressors, this tool uses the Canvas API in your browser — your photos are never uploaded.

FAQ
- Are my images uploaded?
- No. Compression uses the Canvas API in your browser. Files stay on your device.
- Which formats are supported?
- JPG and PNG input. Output is JPG (or PNG if the source was PNG).
- How much can I reduce file size?
- Results depend on the original image and quality setting. Photos often shrink 50–80% at moderate quality.
- Will compression reduce image quality?
- Yes, lowering quality reduces visual fidelity. Use the preview to find a balance between size and clarity.
