Free Image Compressor

Reduce image file size instantly while preserving quality. 100% private processing in your browser.

The image compressor shrinks JPG, PNG and WebP files in your browser — nothing is uploaded, so it is safe for personal photos, client assets and confidential screenshots. Drop in an image, adjust the quality, and download a smaller version that looks the same but loads faster on your website, email or app.

Your image is processed locally in your browser and is not uploaded.

Supports JPG, PNG, WebP

How to compress an image

  1. Click Add image or drag a JPG, PNG or WebP into the tool.
  2. Move the quality slider — lower means a smaller file but more compression artifacts.
  3. Click Download to save the compressed image.

Worked example

A 4.2 MB photo from a phone needs to go into an email that caps attachments at 1 MB. You drop it into the compressor, set quality to 70%, and download a 680 KB JPG that looks the same on screen. The original never left your device, so it is safe to use for a photo of a signed document or a customer's property.

Frequently Asked Questions

Is my image uploaded to a server?

No, all compression happens locally in your browser using native HTML5 Canvas. Your images never leave your device.

What formats can I compress?

You can compress JPG, PNG, and WebP images. Transparent PNGs will be preserved if compressed to WebP, or flattened to white if converted to JPG.

How does the quality slider work?

The quality slider controls the compression level. Lower quality results in smaller file sizes but may introduce visual artifacts.
