Client-side processing

Compression, resizing and conversion run entirely in your browser using WebAssembly and the Canvas API. No file is transmitted when you are using tools as a guest.

No server uploads for guests

Guest sessions have zero network transfer for your image data. The processed file is handed directly back to your browser for download.

EXIF data removed on export

Location tags, camera model and other metadata embedded in JPEG files are stripped during compression, so sensitive details never reach any server.

Common questions

Does Optimage work on iPhone?
Yes. Optimage runs fully in Mobile Safari on iPhone and iPad. No app download is required — open the site, pick your images and download the results.
Do I need to create an account?
No account is needed to use any tool on Optimage. All core features — compress, resize, convert — are available without signing up.
Are my images uploaded to a server?
Guest users' images are processed entirely in the browser using client-side JavaScript. Nothing is sent to our servers. If you sign in to use cloud features, uploads are encrypted in transit and deleted after processing.
Does it work offline?
The tools load from our servers, so an initial internet connection is required. Once the page is loaded, compression and resizing happen locally in your browser and do not require an active connection.
