Best practices for better results

Image optimization works best when you choose the right balance between file size, visual quality, dimensions, format compatibility and privacy. These tips help you get a cleaner result.

  • Start from the original image whenever possible.
  • Review the output before publishing or deleting your original file.
  • Use related tools like resize, convert or metadata removal when you need a more specific result.
  • Choose the right format for the job: JPEG for photos, PNG for sharp graphics and WebP for modern websites.

What happens to your images?

When you choose a file, your browser reads it locally and creates the processed version on your own device. CompressImage.ca does not receive the original image or the finished file.

That local-first approach is useful for personal photos, client work, screenshots, documents, product images and other files you do not want to upload to a third-party server.

When to use another tool

The best tool depends on what you are trying to fix. Compression reduces file size, resizing changes dimensions, conversion changes format, cropping changes framing, and metadata removal cleans hidden information from the file.

JXL to WebP FAQ

Why convert JXL to WebP?

WebP is small and supported by every modern browser, while JPEG XL is not yet. WebP is a practical choice when a JXL image is headed for a website today.

Does WebP keep transparency?

Yes. WebP supports an alpha channel, so any transparency in the JXL is carried through to the WebP.

What quality should I use?

Quality 80 to 90 keeps the image looking identical while cutting the file size. Lower it further if loading speed matters most.

Is my file uploaded?

No. The JPEG XL file is decoded and re-encoded to WebP entirely in your browser, so it never leaves your device.
