Compress image to 200KB

Several quality and format candidates are encoded until one fits 200KB; each result is decoded again and compared (SSIM) so the best-looking one wins. You see the real file size before downloading.

Resolution is kept by default. Only if the target cannot be reached, opt in to shrinking the dimensions.

Your file is never uploaded — it is processed inside this browser.

Are my files uploaded?

Nerulio processes selected files on your device and has no file-upload API. Optional engines and models are downloaded from third parties; those requests expose connection information such as your IP address.

Will my work be saved automatically?

No. Images and editing state stay in this tab; media output can use local temporary storage. Changing language preserves your work; reloading, closing the tab, or following a link to another page can clear it.
