How to use Image compressor

Drop an image. Choose JPG, WebP, or PNG and a quality slider. Watch the estimated size, then download. Typical web heroes land between 80–150 KB at ~1200px — pair with Image Resizer for dimensions.

Add your file

Drag & drop, browse files, or press Ctrl+V to paste from the clipboard where supported.

Process in the browser

Work stays in this tab with WebAssembly, Canvas, or other on-device APIs — your file is not uploaded to Omnipus.

Download or share

Save the result to your device, or share it with the OS share sheet when available.

Direct share: Install Omnipus as an app on Android to share files and links into this tool from other apps.

About this tool

Frequently Asked Questions

Is compression lossless?

JPG/WebP below quality 1 are lossy. PNG stays lossless and may not shrink much for photos.

Max file size?

Very large 4K photos may take a second. Everything stays in memory on your device.

Batch?

Add several files; each compresses independently.

Does this strip EXIF?

Canvas export usually drops camera EXIF — often desirable before sharing.

Is Image compressor completely free to use?

Yes. Image compressor on Omnipus is free to use with no subscription paywall for the tool itself.

Are my files or data uploaded to any servers?

No. Image compressor processes your input locally in this browser tab. Your files and text are not sent to Omnipus. Some tools download an engine or model file the first time you use them; that is a download, not an upload.

Does Omnipus add watermarks to exported files?

No. Omnipus does not stamp a site watermark onto files you export from Image compressor.

Can I use Image compressor on my mobile phone?

Yes. Omnipus has touch-friendly controls and can be installed as an app. On Android you can also share files or links into tools from other apps.
