Are my images uploaded to the server when I compress them?

No. This image compressor works entirely in your browser using the canvas API. Your images are not uploaded or stored on NovaTools Hub servers.

Which image formats does this tool support?

You can compress common web image formats such as JPG, PNG, and WEBP. The compressed output is provided as a JPEG file.

Will compressing my image reduce its quality?

Yes, compression reduces file size by discarding some image detail. You can adjust the quality slider and optional max width to balance size and visual quality.

Compression tips

Use the quality slider to balance file size and clarity. Lower quality shrinks files faster, while higher quality preserves detail for portfolios, product photos, and client approvals.

Set a max width when exporting for web or social to reduce size further.
Keep original files if you plan to edit images again later.
Check the preview before downloading to confirm sharpness and color.
