A small guide to getting started
How to Print Coloring Pages
Print a library picture or your own converted photo on the paper you have. Start with the kind of image you want to print, then check the sheet before using ink.
A picture from the library
- Open any coloring page and choose A4 or US Letter.
- Select Print this page to open a clean print sheet. Wait for the image to load, then press the print button.
- Before direct printing
Even if you choose US Letter on ColorWillow, the print dialog may still default to A4. Check Paper size in the dialog and change it to Letter before printing.
- Check the preview shows one page with the whole drawing visible before printing.
Save a PDF for later
Choose a paper size on the coloring page and select Save as PDF. The PDF is created in your browser using the original PNG, centered on one sheet with the same safe margin.
A Free or AI result
After a Free conversion
- When conversion finishes, keep the result open and select the paper in “Paper size”.
- Choose “Download PDF” to keep a copy, or “Print” to open the print dialog.
- Free printing and PDF download run on your device without an account or credits. Download before closing the page if you want to keep the result.
After an AI conversion
- Wait for the finished result, then select the paper in “Paper size”.
- Choose “Download PDF” to save the file, or “Print creation” to prepare the print sheet. You do not need to generate the image again to change the paper size.
A downloaded PDF or PNG
- Open the PDF in your PDF viewer and choose the matching paper size.
- Start with Actual size or 100%. If the preview clips any part of the drawing, use Fit to printable area and check again; this may make it a little smaller. Avoid Fill or borderless enlargement when they crop the image.
PNG
Open the original downloaded PNG in your image or printing app. Choose the paper size, then Fit to page with the full image visible. Keep its proportions and avoid crop-to-fill. The website’s paper choice does not set the paper size in that other app.
Before direct printing
Match the paper size to the sheet in your printer. For ColorWillow’s prepared print sheet, start at 100% scale, with no additional margins and headers and footers off. The sheet already includes a 10 mm safe margin. Check that the preview shows the whole drawing on one page.
Match the paper in your printer
For US Letter paper, choose Letter (8.5 × 11 in). For A4 paper, choose A4 (210 × 297 mm). Check both the website and the print dialog; they can have different defaults.
Actual PDF previews: the same square flower drawing, centered on one sheet in each size. Open a sample to check the page layout before printing.

Why is there white space around the drawing?

This Letter preview uses the same image and layout as the downloadable sample. The dashed guide marks the area inside the page’s 10 mm (about 0.39 in) safe margin.
A square picture leaves more space above and below it on a portrait sheet. The image keeps its proportions; that extra space does not mean part of it is missing.
The dashed guide is only shown here. It is not printed in the sample PDF. Check your printer’s preview too, because its printable area may differ.
Print several pages together
- Choose “Add to list” on a picture card. Open the print list to remove pictures or change their order. The list stays in this browser tab, expires after 30 minutes without print-list activity and holds up to 10 pictures.
- Choose A4 or US Letter and decide whether to include a cover. Select Print to prepare every picture before the browser’s print dialog opens. A cover adds one sheet.
- You can also download the whole list as one PDF. Canceling preparation or closing the print dialog keeps your list so you can try again.
Arrange a small, usable book
Use the print list for a quick one-picture-per-sheet PDF, with an optional cover. Choose Add to book draft when you want page text or more control over the cover and order. The list stays intact. For a ready-made sequence, start with a book from the coloring book library.
If the print preview does not look right
The edges are cut off or the picture is too small
Use the same paper size on ColorWillow and in the print dialog. For direct printing, choose 100% scale, no extra margins, and turn off headers and footers. The sheet already has a safe margin. If you print the downloaded PNG in another app, use Fit to page instead.
A sheet is blank or there are extra pages
Wait until the pictures finish preparing. Check the preview page count: one sheet per picture, plus one if you selected a cover. Check paper size and margins. If a picture fails to load, cancel, check your connection and retry; you can remove the named picture from the list.
The print dialog does not open
Try the Print button again after preparation finishes. If your browser still does not open a print dialog, download the PDF and print it from your PDF viewer. Check its preview and paper settings before printing.
A note on clarity
A PDF sets the page layout; it does not add image detail. Use the original download, not a screenshot. For Free results, 1024 px can retain more detail than 512 px but takes more memory and requires another conversion; small source photos are not enlarged. If lines still look soft, reduce the print size in your printing app or choose a clearer source.
For sharing or reusing a design, read its usage information first.
