Is this AI image upscaler really free?

Yes. Everyone gets 2 free credits a day, enough for two 2x upscales or one 4x upscale, and downloads have no watermark.

Which image types are supported?

You can upscale photos, anime or illustration art, product shots, screenshots, and most JPG, PNG, or WebP images.

Will my uploaded files be stored permanently?

Guest results are deleted automatically after 7 days. Once you sign in, results stay in your workspace until you delete them — one at a time or in bulk.

Do I need an account?

No — you can start as a guest. Sign in when you want to keep your results or buy credit packs.

Why does 4x take longer than 2x?

4x produces 16x the pixels, so it needs more processing time than 2x. Use 2x for quick previews and 4x for final output.

What do paid credits add?

Nothing is locked behind payment: every mode and tool runs on the free daily credits. Credit packs only add volume — they cover jobs your free credits for the day cannot, and they never expire.
