## What is Raster?

Raster turns your photos into striking halftone and rasterized artwork. Inspired by classic print, pop art and comic styles, Raster rebuilds any image from dots, lines and shapes — perfect for posters, social media, prints and creative projects.

CREATIVE MODES
• Grid — classic halftone dot patterns
• Interlaced — bold scanline and stripe effects
• Radial — dots that radiate from any point
• Photo — subtle rasterization that keeps your detail

SHAPES & STYLES
Build your image from circles, squares, triangles, diamonds and polygons — or turn it into pure ASCII art.

COLOR CONTROL
• Bicolor — bold two-tone looks
• Multicolor — limited palettes with risograph and screenprint vibes
• Full color — keep your original colors with a rasterized texture

PRO TOOLS
• Super Resolution — enhance and upscale your images with on-device machine learning
• Collage — combine several rasterized images into one composition
• High-resolution export and PDF output ready for print

Whether you're making a poster, an album cover, a sticker or a one-of-a-kind profile picture, Raster gives you full control over every dot and shape.

Download Raster and start designing.

### 5/5 — Great poster making app

*2025-06-23, version 2.6.0*

Great app and fabulous customer service and response. Definitely worth it!

### 1/5 — Not able to set size in inches

*2024-11-26*

Not able to set custom inches also when sent to printer print stops and message appears unable to find printer

### 2/5 — needs ability to export to PHOTOS app as individual pix- not pdf

*2024-02-08*

from PDF you cannot print without borders on iOS

from printer app you can select borderless- but only works on photos

please add ability to export as PDF -OR- individual images

### 1/5 — update is terrible

*2022-06-08*

Ever since the recent update I can not resize in INCHES only METERS. The settings gives you an option to use inches or meters. I have INCHES checked but it ONLY displays the resize in METERS. Please fix this

**Developer response:** Mrs Fonville,

The bug has been fixed, please update your application to 2.5.0 or later.

### 1/5 — :(

*2022-02-02*

Was 5 star until you had to pay to make it.

**Developer response:** Hello,

The application has free features and some more complex are included in the PRO version to help supporting development costs.

### 1/5 — won’t export to print

*2022-02-02*

I had no issues with the app prior to update. I updated and paid the new “Pro” fee and now i can’t export images.

**Developer response:** Hi, We are sorry that you did not manage export your poster. Maybe the way to save your file was not clear enough. Please feel free to reach out to contact@rasterapp.com so that we can help you.

### 1/5 — Can’t resize image

*2022-01-05*

The new update took away the ability to adjust the size of your image within the pages. Before you could do say 3x4 pages of paper and manually shrink or enlarge the image however you want in the parameters, now you cannot. Even after paying the 3.99 upgrade fee to Pro, it does not allow this anymore. Please fix this issue as it’s a crucial feature.

**Developer response:** Hello,
The latest update brings the cropping back, please check the crop setting!

### 1/5 — Doesn’t print out

*2020-11-11, version 1.6.0*

You can choose the image 
Decide the size 
Export to a pdf 
But when you try and print it out nothing 
And I know it’s not my printer because that’s working fine everywhere else 
It would be really cool if this worked

### 1/5 — Overall not the best

*2020-10-21*

I payed $1.99 for the full version that didn’t even last over an hour and it didn’t even work when you try to print larger photos

**Developer response:** Hi, We are sorry that you did not manage to get your expected result.Please feel free to reach out to contact@rasterapp.com so that we can help you.

### 5/5 — Wow!

*2017-02-28, version 1.3.0*

Great way to make wall-sized posters from any image on your phone! Free version allows good sizes, and the paid gives any size and any option. Seems like a pretty good deal to me!
