A free image upscaler that does not ask for anything first

What you get without signing up

Two upscales a day, up to 4 megapixels out, no account, no card, no watermark, full download. That is the whole free tier and there is no step after it where the file is held back. A free account raises it to three a day at up to 8 megapixels and grants a batch of credits for anything larger, still without a card.

Why the daily cap exists, honestly

Because this one costs us money to run. Most of the editor is free because it executes in your browser and costs nothing to give away — an unlimited offer there is easy. An upscale is real GPU time on somebody’s hardware, so an unmetered version would be a promise we would quietly have to break later. Two a day is what we can hand out without that happening, and we would rather say so than dress a limit up as a feature.

It is not a resize

Enlarging in Photoshop, GIMP or Preview interpolates — it averages between the pixels you already have, which produces a bigger file with no more information in it. A model reconstructs instead: it has seen enough edges to rebuild what a boundary ought to look like at four times the size. That is why the result reads as sharp rather than as a smooth enlargement. It also means the gain is biggest on photographs, where there is real texture to rebuild, and smallest — occasionally negative — on flat type, where a reconstructed letterform can come back subtly the wrong shape.

The part most upscalers do not tell you

The picture is uploaded. That is unavoidable for a model of this size and we are not going to imply otherwise — the rest of this editor runs in your browser and genuinely transmits nothing, which is exactly why it matters to be precise about the one tool that does not. The source is deleted the moment the upscale returns, held under a storage rule that clears anything left within 24 hours, and is never used to train a model.

What it is actually for

It exists because print work keeps arriving too small — a logo lifted off a website that now has to go on a shirt, a customer supplying the only file they have. It sits alongside a full layered editor rather than on its own, so the upscaled result can go straight into colour separation, background removal or a layered PSD without a round trip through another tool.
