Compress images without uploading them

  • Useful for IDs, forms, internal screenshots, and private photos.
  • Free to use with no sign-up, email, or account required.
  • No server upload: selected image files stay on your device.
  • Batch ZIP export for forms, email, websites, and repeat upload tasks.

FAQ

Are my images uploaded to PicZip?

No. PicZip compresses selected images in your browser. Your image files are not uploaded to a PicZip server for compression.

Is PicZip free to use?

Yes. The core image compressor is free to use and does not require an account, email address, or subscription.

Which image formats are supported?

PicZip supports JPG, PNG, and WebP images. You can keep the original format or choose a different output format when smaller files matter.

Can I compress multiple images at once?

Yes. You can add multiple files, compress them in sequence, and download the results as one ZIP file.

Why does a target size sometimes need lower quality?

A strict target like 100KB may require a lower quality value or smaller dimensions, especially for large photos with many details.
