Drag the frame or use the arrow keys to move it. The frame is exactly A3 (297 × 420 mm), so the print fills the page.

How it works

From photo to a printable paint-by-numbers kit in under a minute, with no account and nothing to install.

  1. Upload a photo

    Pick any JPG, PNG or WebP, or paste one straight from your clipboard. Clear subjects in good light work best, and faces should fill a good part of the frame.

  2. Frame it and choose the detail

    Drag the A3 frame over the part you want, pick portrait or landscape, and choose 8 to 36 colours. Fewer colours and bigger areas are easier for beginners.

  3. Print it and paint

    Download a three-page A3 PDF: the numbered outline to paint on, a colour key with mixing recipes from basic acrylics, and a full-colour preview to work from.

Frequently asked questions

Is OutlineArt free?

Yes. There is no sign-up, no watermark and no limit on how many patterns you make.

Are my photos uploaded anywhere?

No. All the image processing happens in your own browser, so your photos never leave your device. You can even disconnect from the internet once the page has loaded. The site counts anonymous visits with Vercel Web Analytics, which uses no cookies and never sees your photos.

What is in the PDF?

Three A3 pages: the numbered outline to paint on, a colour key that lists every paint number with a mixing recipe and its hex colour, and a full-colour preview of the finished painting.

How should I print it?

Print page 1 at A3, "Actual size" or 100%, on thick paper or card (200gsm or more) so it takes paint well. The colour key and preview are fine on normal paper. You can scale it down to A4 with "Fit to page", but the areas get small.

Which paints do I need?

A basic acrylic set is enough: white, black, red, yellow, blue, burnt sienna, green and magenta. Each colour in the key comes with a recipe such as "3 White + 1 Blue". Treat it as a starting point and compare with the swatch as you mix.

How many colours should I choose?

Around 12 colours with Relaxed detail suits beginners and children. 24 or more with Fine detail keeps faces and small features sharper, but means many more tiny areas to paint.
