Queue up to 500 photos at once

Make it this big: a percentage of each photo's own size, or an exact width or height with the aspect locked. The rule step shows the factor each photo needs before anything runs.

Step 1 of 3 · Files

Drop photos or a folder — or one photo to review.

A directory or a selection becomes a queue with one rule for every picture in it. A single photograph — dropped, picked or pasted — opens the review studio instead, with a before and after at 100%.

Pixels are read and worked in this tab; model files travel to it, never the other way.

What you are shown before anything runs

— and — minutes

files · tiles · milliseconds a tile, measured over real tiles cut from your own photographs a moment ago, and the name of the graph those numbers describe.

The blanks are blank on purpose. Nothing on this page quotes a duration it has not timed on the machine it is running on, which is why the estimate arrives after the set and not before it.

Model weights come from our model file server only when you press the control that names their size. Everything else — the runtime, the decoding, the inference, the archive — is served from this domain and executed here.

What this does differently

No requirement and no megapixel field: this is the plain “make it this big” control. Pick a percentage or an exact width or height and see the result in pixels before anything runs. To reach a pixel floor across photos of different sizes, the increase image resolution page solves it per photo instead.

What it will not do

  • Unlocking the aspect ratio is not offered: a stretched photo is a damaged photo.
  • Nothing here shrinks a photo.
  • Above four times, the extra size is resampling, not model detail.

Questions about this

Can I type an exact width?
Yes. Choose an exact width or height, type the number, and the other side follows the photo's own aspect ratio, so nothing is stretched.
What does 150% mean here?
Each side multiplied by 1.5: a 1,200 × 800 photo becomes 1,800 × 1,200. Each row shows the before and after pixels and the factor.
Will it make my photo smaller?
No. Nothing on this site shrinks a photo; a photo already at least as big as the size asked for is kept as it is.
Is a bigger image a sharper image?
Not by itself. Above the model's own magnification the extra pixels are resampled, and the detail check says whether the output carries more detail than a plain enlargement.
