How to use
Compress images in your browser and download JPG, PNG or WebP output. Choose a supported image, select a sensible output quality and format, then run compression and download the result. Compare the exported dimensions and file size with the original.
Choose a sensible compression target
Image compression trades file size against visual detail. A moderate quality setting is often a better starting point than the lowest possible setting. Photographs can tolerate some loss that would be obvious in screenshots, diagrams, interface captures or images containing small text. Compare the exported image at its intended display size before deciding which version to keep.
Compression workflow
- Keep the original image as a backup.
- Resize oversized dimensions before compressing.
- Choose an output format supported by the site or app where you will use it.
- Inspect fine edges, gradients and text for visible artifacts.
- Check the exported file size and dimensions before uploading.
Compression results vary with the image and selected settings. A smaller file is not automatically a better result if important details become difficult to see.
Privacy and limitations
Image compression happens locally in your browser. The page loads standard site analytics; it does not upload the selected image to a Tolvix processing server. Browser support and available output formats can vary by device.

Are my files uploaded?
No. File processing runs in your browser; the selected file is not sent to a Tolvix processing server.
Will all features be preserved?
