You just printed out your perfect photo and wow – it looks awful!

The image is blurry and pixelated, nothing like how sharp it appeared on your computer screen.

What went wrong?

This common issue is caused by something called low “DPI.”

DPI stands for “dots per inch” and refers to the number of dots or pixels squeezed into every inch of an image. Pictures that look fine on screens at 72 DPI often need about 300 DPI to print well.

Luckily, there’s a quick, free trick to rescue your prints without buying Photoshop.

While the video above is detailed, you can also keep reading to learn how to easily increase the DPI of images before you print them out.

I’ll explain step-by-step so you can quickly fix blurry picture prints for good.

Why Low DPI Makes Prints Look Bad

To understand the blurry print problem, imagine stretching a small photo across a large poster. When expanded too far, the pixels get gappy and distorted. The photo data wasn’t dense enough for that size.

Printers run into the same issue trying to fill an inch of paper with only 72 pixels. Photos from the web or devices are often 72 DPI – fine for screens but too pixelated when printed.

By increasing an image to 300 DPI before printing, you pack 4 times more pixels into every inch. This extra density makes prints sharp and beautiful.

The Easy Fix: Use Photopea to Change DPI

Don’t waste money on Photoshop just to increase print quality! Instead, use the free online tool Photopea.

Photopea works right in your web browser. It lets you tweak resolution along with other handy edits. The best part – no downloads, accounts, or charges are required.

STEP 5: Click OK to finish.

It takes less than a minute! Photopea automatically changes the DPI without altering photo dimensions. Plus, you can batch-edit multiple images at the same time.

However, the issue with this process is that it automatically resizes the image. Yes, it changes the DPI, but you end up with a larger image.

If you want to change the DPI of your image without altering its size, there is one step you should follow.

Now when you print, ink fills hundreds more dots per inch for stunning quality. No more ugly, blurry pixelation ruining your hard work.

Extra Tips to Maximize Print Results

Along with adjusting DPI, a few other quick tweaks can really make your printed photos shine:

Crop to standard photo ratios like 5×7 or 8×10 to avoid warping or cropping by the printer.

Convert to CMYK color mode which uses ink cartridge colors instead of on-screen RGB colors.

Add a slightly sharpened filter to offset softening from print publication.

Save final files as high-quality JPEGs to keep printable file sizes reasonable.

Following this complete workflow guarantees eye-popping prints ready to frame and proudly display!

Avoid Resizing When Changing Resolution

One key point about boosting image resolution is to do it without resizing if possible.

Here’s why:

When you resample or resize a photo, the software inserts new estimated pixels instead of actual image data. This risks a slight quality loss through interpolation.

By just inputting a new DPI, you stick to the original pixels captured in your picture. No risky guessing or filling in data is needed! This yields the crispest, truest prints from your images.

The Photopea method outlined above keeps dimensions intact for this reason. But if you MUST resize an image, try to only scale up by 10-20% for minimal interpolation.


Bad-quality prints can ruin all your hard photography work.

But armed with the easy DPI-boosting tricks above, you can now rescue disappointing prints for high-quality results every time – without costly software.

So free your photos from pixelated printer prison! Head to Photopea now to bump image resolution before you print your next masterpiece.
