Is it safe to compress a photo of my ID or residence permit online?

It depends on the site. The main risk with online compressors is that they upload your image to their servers to process it there. With this tool the image is opened and compressed inside your browser using Canvas, it is not uploaded to any server, and the output carries no EXIF data. What remains is handling the copy that lands on your device with care.

Where the risk really is

When you upload a photo of your ID, residence permit or passport to a server-based compressor, a copy now sits on a machine you do not control. You do not know how long it stays, who can reach it, or whether it ends up in logs or backups. One image of such a document carries your name, ID number, date of birth and face together, which is exactly what someone needs to impersonate you.

What this tool does with your photo

  1. When you choose the photo, the browser reads it straight from your device without sending it over the internet.
  2. The Image compressor draws the image onto a Canvas element inside the page itself, applying the correct orientation.
  3. The browser re-encodes that drawing as JPEG or WebP at the quality you pick.
  4. The resulting file lands in your Downloads folder. There is no upload step at any point.

Because the image is redrawn, the EXIF data stored in the original, such as the location, phone model and time taken, does not carry into the output. That is a bonus when you send a document photo to someone. If you want to check what a file contains before sending it, inspect it with the Image metadata inspector and remover tool.

How to check for yourself

On a computer, open your browser's developer tools, go to the Network tab, and compress a photo. You will see that none of the requests that appear carry your image file. It is a good habit for vetting any online tool before trusting it with documents, not just this one.

What is still your responsibility

  • The compressed copy goes to your Downloads folder. On a shared or work computer, delete it once you are done.
  • Browser extensions can sometimes read page content. Use a browser without untrusted extensions when handling sensitive documents.
  • Sending the compressed photo by chat or email is a separate step. Send it only to the party that actually asked for it.
  • Avoid keeping document photos in a camera roll that syncs automatically to a cloud account you never check.

Common questions

Does it work on a phone without uploading too?

Yes, it works the same way in a phone browser: the processing happens on your device.

Will compression make the document details hard to read?

Push the quality too low and small numbers can suffer. Start at 80 and zoom into the preview to make sure every number is readable.

Does the tool remove the location from the photo?

Yes, EXIF data is not carried into the output because the image is redrawn.
