I’ve been experimenting with graphics tools for years, and over time, you realize you don’t actually need a massive all-in-one suite. Half of the time, I just need something quick and precise to do one simple task, such as getting the HEX values for a color palette or resizing an image. That’s why I’ve started building a “mini” toolkit of open-source graphics apps that let me take care of smaller tasks without slowing me down. They’re not just freebies; they’re very lean and reliable, and in some cases, surprisingly powerful.

Some of them are ultra-specialized, while others pack more features into one lightweight package, giving me enough power to replace some of the heavier apps in my editing stack. I mainly care about speed, a frictionless user experience, no paywalls, and a little more ownership. Here are the small open-source graphics tools that have replaced a portion of my traditional graphics workflow…

Colorpicker

Get exact values for a color palette

One of the constants in any graphics workflow will always be color values, especially when it comes to design work. You need consistency across every asset and screen, especially for things like UI components or branding, and it also makes scaling projects easier.

This is where Colorpicker comes in for me. It’s a tiny utility that ended up replacing a whole chain of heavier tools. Instead of opening a full graphics editor just to sample a color, this app does only one thing: it lets you pick precise color values from anywhere on your screen, instantly.

Once it’s running, you can sample any pixel and get its HEX, RGB, or HSL values without interrupting your design process. Even though it’s a very basic little tool, it comes with a surprising number of configurations, such as the appearance of your color picker box and displaying the selected color in real-time.

I also like that it has a Colorsbook feature (accessed through the settings). This lets me create custom color palettes and save them for reference later on. It’s a seriously underrated utility to have in your back pocket.

LazPaint

A lightweight graphics app for designing simple assets

LazPaint isn’t exactly “tiny” compared to a single-purpose utility like a color picker, but it’s incredibly lightweight compared to something like Inkscape in terms of system resource usage and software complexity. This is the tool I use for tasks that would normally require me to start up a heavier app like Inkscape, Krita, or even Photoshop.

It packs enough features for painting, editing, and basic image manipulation while staying fast and responsive. For smaller, day-to-day graphics, like button ideas or quick sketch wireframes, it’s the perfect tool to reach for without waiting minutes to start working or worrying about your fans ramping up, even on lower-end machines. It’s the perfect balance between capability, speed, and resource efficiency.

The toolkit is quite impressive for such a small app. It includes layers, selections, filters, brushing, basic effects, text editing, and a couple more, which are often all I need for quick design tasks. It also supports common file formats like PNG, JPG, and BMP without forcing you into proprietary file types.

For someone building a lean graphics toolkit, LazPaint replaces the need for heavier editors when you don’t need the full power of a vector or professional bitmap suite. It’s also a great option for more seasoned editors who need one lightweight tool for quick outlining or experimentation.

Flexxi

The flexible image resizer

Flexxi is another tiny open-source utility that replaced my need for opening a heavy app just to resize my images. And it saves real time when you have to deal with lots of images quickly. It’s a lightweight app designed for Windows, specifically for batch resizing images. But it also resizes, rotates, compresses, and renames images.

One of the image-related tasks I do the most on a day-to-day basis is resizing them, such as the screenshots in these articles I write, and I got tired of opening a full editing app just to do it. Flexxi lets me do the job without starting up a heavy editor, plus I don’t have to resize every image one at a time. I can set my dimensions once and run them across a folder in no time.

The Convert feature also comes in handy as the CMS I work in requires a specific format, so I don’t need to use a heavier, dedicated converter tool or upload my shots to online converters anymore. Overall, Flexxi is a tiny app with one purpose: reduce repetitive grunt work for super basic tasks like resizing and conversion.

A lean graphics kit just works better

Building a lightweight, open-source graphics toolkit isn’t about matching the flashy tools in my heavier setups. It’s about reducing the workflow friction and system demand for basic and repetitive tasks. Each utility solves a specific issue - Colorpick lets me grab color values in no time, LuxPaint lets me do test runs for design ideas, and Flexxi batch-processes my images in a flash. This new little stack also improves my workflow with the heavier apps I still use, since the small and boring stuff is already taken care of.
