Will a Low-Resolution Photo Work on a Custom Puzzle?

It depends on the detail the photo actually holds and the finished size you choose, not on the piece count. The 100 XL and 500 both finish at 13.5 x 19 in, so switching between them does not change how sharp a photo looks; the 99 is a compact 3.5 x 5.1 in and the 1000 is 19 x 27 in. A smaller finished print can make limited detail less noticeable, but it does not restore detail the file lacks. We review uploaded photos before production for quality, cropping and composition and contact you if something needs adjusting. Our free photo resolution checker compares a file's pixel count with the puzzle sizes; treat its result as advisory, because it does not judge focus, movement or what your crop removes.

What Counts as Low-Resolution for a Puzzle

Low resolution means the file has too few pixels for the detail you want at the finished size you choose. No single megapixel figure makes a photo acceptable, because focus, movement, compression and how much the crop removes matter as well. Check these instead:

• Pixels after cropping. Count the pixels in the part of the photo you will upload, not the original frame. The product page recommends 4 MP or higher for the 500 and 1000-piece versions; that is a recommendation, not a guarantee of sharpness.
• The essential detail. Zoom in to see whether the faces or other details that matter were captured clearly, then judge them at the finished size rather than at the zoomed screen size.
• The finished size. The same file covers 13.5 x 19 in on both the 100 XL and the 500, 19 x 27 in on the 1000 and 3.5 x 5.1 in on the 99.
• Where the file came from. Screenshots, social-media downloads and messaging-app copies are often compressed versions of a larger original.

The Fix When the Photo is What You Have

Sometimes the photo you want is the only photo you have. A grandparent's old wedding photo scanned at low resolution. A friend's text message of a treasured pet shot. A favorite social-media memory you cannot find the original of. Three steps can help:

• Look for a better original. If the photo came through a social platform or messaging app, a larger original may exist on the phone that took it, in a cloud backup or with the person who sent it. It may not, so check before relying on it.
• Consider a smaller finished size. The 99 at 3.5 x 5.1 in is the compact option, and a smaller print can make limited detail less noticeable without restoring it. Switching from the 500 to the 100 XL does not make the print smaller, because both are 13.5 x 19 in.
• Upload the best version you have. We review uploaded photos before production for quality, cropping and composition and contact you if something needs adjusting. There is no separate proof step, and editing cannot add authentic detail the file never captured. If the photo has other problems alongside resolution (blurry, too dark, cropped tight, or too many small faces), our photo puzzle troubleshooting guide diagnoses each one and points to the right next step.
