Blow Up keeps photos crystal clear during enlargement.

Especially in large prints hung on a wall, the difference between Blow Up and Photoshop is astounding. Version 3 makes pictures even sharper without computer artifacts.

If you understand Photoshop’s resize command then you already know how to use Blow Up. Our large library of standard paper sizes makes it even easier. With Lightroom and CMYK support, Blow Up fits into a professional workflow.

“Blow Up has been a real time and money saver in our business, as we do not have to purchase stock photography in as large a range of sizes as before.”

Guy Atkins, Employee Engagement Design

“For me, Blow Up isn’t just making the final piece look good, it actually frees me up to work at the speed I need to during the painting process. After using Blow Up, we realized with a few tests that we could enlarge my illustrations up 700% before we started to see any sort of quality fall off.”

Brian Edward Miller, Orlin Culture Shop, Denver, CO

“I was AMAZED at the detail Blow Up was able to produce. The grain adds just the right amount of ‘film-like-ness’ so that the result doesn’t look like an upsized digital file at all.”

Geoff Smith

“If a photo has good resolution and clarity, you can easily enlarge it with Blow Up to an incredible size.”

Enrique Coleccion

Image Quality

In Blow Up 3 we found ways to make edges even sharper without introducing computery artifacts. The images below show the difference between Blow Up 3 and the traditional bicubic photo resizer used by Photoshop and other image editors.

Blow Up’s interface is deceptively simple. Just set your paper size as you would in Photoshop and optionally set a crop region. In version 3 we kept all the rocket science under the hood. Watch our short videos or try Blow Up yourself for free to see how easy it is.

Blow Up 3 runs faster on both Macintosh and Windows computers.

Huge Images

You can resize up to 300,000 pixels per side, the maximum Photoshop can handle. Of course, Photoshop would choke on a square image that big, but if you are making a billboard that Photoshop can handle, so can Blow Up!


Blow Up can handle CMYK images used in offset printing and 16-bit/channel images used by professional photographers.


Blow Up has presets for common paper sizes, including photo papers and standard US, European, and Japanese sizes.

Output Sharpening

Just choose your paper type and Blow Up sharpens the right amount to compensate for ink diffusion.
