Three steps, and you decide how bold or detailed the outlines are before you print.
Pick a JPG, PNG, or WEBP file of a pet, a child, a flower, or a favorite place. It opens directly in your browser and is never uploaded.
Choose a preset or set line thickness, detail, and smoothing yourself. The preview redraws as you move each slider.
Download a print-ready PDF in A4 or Letter, or save a PNG image, then print at 100% scale.
The same photo, converted to outlines. Bolder lines suit younger children; finer lines keep more of the original detail.
A pet photo with the Kids Bold preset: thick, easy-to-color outlines.
A flower with the Simple Cartoon preset: balanced outlines with room to color.
A house scene with the Fine Realistic preset: thinner lines that hold detail.
Three common uses. Each one is free and runs entirely in your browser.
Convert a photo of your dog, cat, or other pet into thick outlines that are easy for children to color. The Kids Bold preset gives the boldest lines; crop close to the animal for the cleanest result.
Make worksheets from your own classroom or field-trip photos, which sidesteps the copyright problems of downloading images online. Export as A4 or Letter and print a set for the whole class.
Export a PDF and print at 100% (Actual size), not Fit to page. A4 portrait suits most home printers. If the outlines print too thin, raise the Line thickness slider before exporting.
Yes. Uploading a photo, adjusting the outlines, and downloading a PDF or PNG coloring page are all free. There is no account to create, no watermark, and no limit on how many pages you make. The only optional extra is a small footer credit that you turn on yourself in the export dialog.
Your photos never leave your device. The conversion runs entirely in your web browser using JavaScript and a Web Worker: the image is read from your computer, turned into line art locally, and discarded when you close the tab. Nothing is uploaded to a server, stored, or shared with anyone.
You can upload JPG, PNG, and WEBP images up to 15 MB. Large photos are scaled down automatically (longest side to about 1600 pixels) so processing stays fast. You can export the coloring page as a print-ready PDF in A4 (210×297 mm) or US Letter (216×279 mm), or as a PNG image.
Export a PDF, open it, and set printing scale to 100% or "Actual size" rather than "Fit to page," so the outlines keep their proportions. Choose Portrait or Landscape in the export dialog to match your photo. A4 or Letter at 100% prints correctly on any home or office printer.
Photos with a clear subject, even lighting, and a plain background convert best, because the tool draws outlines where light and dark areas meet. Close-ups of a face, a pet, a flower, or a single object give the cleanest lines. Busy backgrounds, low contrast, or strong shadows add clutter — crop tighter, or raise the Smoothing and Edge strength sliders to simplify the result.
Faint outlines mean the edges are weak: lower Edge strength so more edges are kept, or raise Line thickness for bolder lines. Too many messy lines mean there is too much detail: raise Smoothing and Edge strength, or lower Detail, to keep only the main shapes. Simple Cartoon is a balanced starting point, Kids Bold gives the thickest lines, and Fine Realistic keeps the most detail.
Yes to both. The tool works in mobile browsers on iOS and Android as well as on desktop. You own the coloring pages you create and may print them for home, classroom, or commercial use, as long as you hold the rights to the original photo you upload. Teachers often use their own classroom photos to avoid copyright issues.
