5 Best Online Halftone Filter Tools Compared (2026)
There are surprisingly few online tools that do halftone conversion well. Most of the results you get from searching are either broken, abandoned, or want you to pay before you can even see what the output looks like. I spent an afternoon testing every half-decent halftone tool I could find, so you do not have to.
Here is the honest comparison. Yes, I made one of these tools. No, I am not going to pretend the others do not exist.
| Tool | Price | Real-time Preview | Dot Shapes | Output Size | Server Upload? |
|---|---|---|---|---|---|
| ScreenPrintFilter.online | Free | Yes | 4 (Circle/Square/Diamond/Line) | Original + custom | No (client-side) |
| IMG online | Free | No | 1 (Circle only) | Fixed small sizes | Yes |
| Halftone Pro | $15/mo | Yes | 6 (incl. Cross, Star) | Custom | No |
| Photopea | Free / $9 ads-free | Yes (editor-based) | 1 (need manual filter setup) | Custom | No |
| ConvertImage | Free with watermark | No | 2 (Circle, Stripes) | Fixed | Yes |
Full disclosure: This site (ScreenPrintFilter.online) is listed first because I made it. I tried to be fair in the comparison below. Judge for yourself.
1. ScreenPrintFilter.online
https://screenprintfilter.online
The tool you are currently on. It does one thing — halftone conversion — and tries to do it well. Everything runs in the browser using Canvas. No file uploads, no servers, no accounts.
- Actually free, no hidden limits
- Real-time preview as you adjust sliders
- Full resolution output
- 4 dot shapes
- Undo/redo support
- Zoom + magnifier for detail check
- No uploads = private
- Only 4 dot shapes (no custom patterns)
- No multi-channel color separation
- Single-page tool, not a full editor
2. IMG online (imgonline.com)
https://www.imgonline.com.ua
An old-school website that looks like it was designed in 2008. It works, but barely. You upload your image, set some parameters, hit a button, wait for the server to process it, and download the result. No preview. No iteration. If the settings are wrong, you start over.
- Free
- Has some other image tools too
- Works in a pinch
- No preview — guess and check
- Uploads your files to their server
- Output resolution is limited
- UI feels ancient
- Only circle dots
3. Halftone Pro (halftonepro.com)
https://halftonepro.com
A more polished tool that runs as a PWA. Has more dot shapes than most free tools and handles larger images well. The catch is the pricing model — $15/month for a tool that only does halftones. For professionals doing this daily, it might be worth it. For occasional use, the subscription feels steep.
- 6 dot shapes including cross and star
- Good real-time preview
- Works offline (PWA)
- Client-side processing
- $15/month is expensive for a single tool
- No free tier with full features
- Can feel overengineered for simple tasks
4. Photopea (photopea.com)
https://www.photopea.com
Photopea is a free online Photoshop clone. It is incredibly powerful for a web app. You can do halftone effects through the filter menu, but it is not straightforward. You need to convert to grayscale, apply the Color Halftone filter, adjust the channel settings manually... it takes a few minutes even if you know the steps. If you already use Photopea for other image work, it makes sense. If all you need is a halftone, it is unnecessarily complicated.
- Full photo editor for free
- Lots of control if you know what you are doing
- No uploads needed
- Steep learning curve for halftones
- No dedicated halftone preview
- Layered interface is overkill
- Ads on the free version
5. ConvertImage (convertimage.net)
https://convertimage.net
One of those sites that does a hundred different image conversions and none of them particularly well. The halftone feature exists but it is buried. You upload your image, choose the effect, and the site slaps a watermark on the output unless you pay. The output resolution is also capped fairly low. Honestly, skip this one.
- Has other image tools bundled
- Free with watermark
- Watermark on free version
- Server-side processing (uploads)
- Low resolution output
- Only 2 pattern types
- Slow
Which One Should You Pick?
It depends on what you need:
- Need a quick halftone, no hassle? Use ScreenPrintFilter.online. It is free, fast, and runs locally.
- Need more dot shapes? Try Halftone Pro, but be ready to pay.
- Already using Photopea? Stick with it, but learn the filter workflow.
- Just browsing? Try a few and see which workflow clicks for you.
Personally, I would not pay $15/month for a halftone tool unless I was running a print shop doing hundreds of orders. For everyone else, the free options are good enough.
