Everything runs locally on your device. Your images never upload to Focera servers — private by design.

Before & after preview

Compare quality with a slider, then download JPEG or WebP ready for the web, forms, and messaging apps.

How It Works

Reducing image size should be fast and private. Focera keeps the whole flow on one page — upload, choose a compression level, compress, and download without an account or desktop installer.

  1. Upload your image. Drag and drop a JPG, PNG, or WebP file up to 10 MB, or click the zone to browse from your device.
  2. Pick a level and format. Extreme and Strong save the most space; Balanced is a solid default; Light keeps more detail. Choose Auto, JPEG, or WebP output.
  3. Compress and download. Processing runs in your browser. Compare sizes and quality, then download again anytime.

Jump back to the image compressor anytime to process another file.

FAQ

Is this image compressor free?

Yes. Upload, compress, preview, and download with no account, subscription, or credit card.

Are my images uploaded to a server?

No. Compression runs entirely in your browser. Your files stay on your device.

How does compression work?

Your image is optionally resized to a max dimension for the chosen level, then re-encoded as JPEG or WebP at a lower quality. Stronger levels use lower quality and smaller dimensions for more savings.

Which formats are supported?

Upload JPG, PNG, or WebP files up to 10 MB. Output can be Auto, JPEG, or WebP.

Will quality look the same?

Light keeps more detail; Extreme saves the most space. Use the before/after slider to judge quality, then try another level if needed.

Do I need to install software?

No. Open the page in a modern browser, drop your image, and compress immediately.

Can I use the results commercially?

Yes. Compressed files you download are yours to use in marketing, web, client work, and personal projects.
