What you need to start making an image

You need three things: a tool that lets you draw or arrange shapes, a place to put your work (your computer, phone, or a website), and an idea of what size and format you want the final image to be. You do not need to be an artist. Most image-creation tools now include templates, stock photos, and pre-made shapes so you can build something without drawing by hand.

The tool you pick depends on what you are making. A straightforward social media post uses different software than a poster for your wall, which uses different software than a logo you want to print on a t-shirt. The difference matters because each format has its own size requirements and file types that work best.

Key Takeaways

  • Start by deciding what size your image needs to be and what you will use it for, because this determines which tool and file format will work best.
  • Free tools like Canva, GIMP, and Pixlr let you create images without installing software, while Photoshop and Illustrator cost money but offer more control for detailed work.
  • Raster images (made of pixels) work for photos and social media; vector images (made of shapes) work for logos and designs that need to scale up or down.
  • Save your work in the right format for where it will be used: PNG or JPG for websites and social media, PDF or SVG for printing or resizing.

Choosing between raster and vector before you start

A raster image is made of tiny colored squares called pixels. Photographs are raster images. When you zoom in on a raster image too far, it gets blurry because you are seeing the individual pixels. Raster tools include Photoshop, GIMP, Pixlr, and Photopea. Use raster when you are editing photos, creating digital paintings, or making images with lots of color detail and shading.

A vector image is made of shapes and lines described by math, not pixels. When you zoom in on a vector image, it stays sharp because the computer redraws it at any size. Vector tools include Illustrator, Inkscape, and Canva. Use vector when you are making logos, icons, diagrams, or anything you might need to print large or resize later without losing quality.

If you are not sure which one you need, start with raster. Most people create raster images most of the time. You can always convert a raster image to vector later if you need to, though the process is not perfect.

Setting up your canvas with the right dimensions

Before you open a blank canvas, know what size your image should be. This is measured in pixels for screen use and in inches or centimeters for print. A social media post for Instagram is 1080 by 1080 pixels. A Facebook cover is 820 by 312 pixels. A poster you want to print at 11 by 17 inches should be created at 3300 by 5100 pixels if you want it to print clearly (that is 300 pixels per inch, the standard for print).

Most tools let you choose a preset size when you create a new image. Canva has presets for Instagram, Facebook, Twitter, Pinterest, and dozens of other platforms built in. GIMP and Photoshop let you enter custom dimensions. If you are making something for print and you are not sure of the size, ask the printer what dimensions they need before you start.

The resolution matters for print. Screen images can be 72 pixels per inch. Print images should be 300 pixels per inch. If you create a small image at screen resolution and then try to print it large, it will look blurry.

Using templates and stock images to build faster

You do not have to start with a blank canvas. Canva, Adobe Express, and Pixlr all include thousands of templates for social media posts, flyers, business cards, and presentations. A template gives you a starting point with the right dimensions, placeholder text, and design elements already arranged. You change the text, swap in your own photos, and adjust colors to match what you want.

Stock photo sites like Unsplash, Pexels, and Pixabay let you read photos for free and use them in your images. Canva includes stock photos built in. If you use a stock photo, check the license to see whether you can use it commercially or only for personal projects. Most free stock photos allow both, but some have restrictions.

Templates and stock images are fastest for social media posts, event flyers, and one-off graphics. If you are building a brand identity or something you will use many times, starting from scratch gives you more control over how it looks.

The steps to create a basic image in a free tool

This example uses Canva, which works the same way on phone and computer. Open Canva.com, click "Create a design," and choose the size you want (or search for the platform, like "Instagram post"). Canva shows you a blank canvas with the right dimensions.

On the left side, you see tabs for Elements (shapes and icons), Text, Photos, and Uploads. Click Elements and drag a shape onto your canvas. Click Text and add words. Click Photos and search for an image to add. Drag anything around to move it. Click it again to resize or rotate it. Change colors by clicking the color swatch next to any element.

When you are done, click read. Canva asks what format you want: PNG (best for images with transparency), JPG (best for photos), or PDF (best for printing). read it to your computer. That file is now your image.

Working with layers to organize your design

A layer is like a transparent sheet stacked on top of other sheets. Your background might be one layer, your text another, and your images a third. Layers let you edit one part of your image without affecting the others. You can hide a layer, move it forward or backward, or delete it without touching anything else.

Canva shows layers in a panel on the right side of the screen. GIMP and Photoshop show them in a Layers panel you can open from the menu. Each time you add text, an image, or a shape, it becomes a new layer. Click a layer to select it, then edit only that layer. This is especially useful when you are working on something complex and you want to change one element without starting over.

If you are new to layers, do not worry about them at first. You can create straightforward images without thinking about layers at all. As your images get more complicated, layers become the tool that saves you time.

Saving and exporting in the right format

When you save your work, you have two choices: save the project file (so you can edit it later) and export the image (so you can use it somewhere). In Canva, you read the image directly. In GIMP or Photoshop, you save as XCF or PSD (the project format), then export as PNG, JPG, or another format.

For social media and websites, use PNG if your image has a transparent background or JPG if it does not. For print, use PDF or a high-resolution PNG. For a logo or design you might resize later, use SVG (vector format) if your tool supports it. Do not use BMP or GIF unless you have a specific reason.

Keep your project file (XCF, PSD, or Canva link) so you can edit it later. Export the image in the format you need for where it will be used. Many people make the mistake of saving only the exported image and then losing the ability to edit it.

Frequently Asked Questions

What is the difference between PNG and JPG?

PNG supports transparent backgrounds and works well for graphics with solid colors or text. JPG compresses photos and works well for images with lots of color detail, but does not support transparency. If you are not sure, PNG is safer because it handles more situations.

Can I use an image I found on Google Images?

Not without permission. Most images on Google Images are copyrighted. Use stock photo sites like Unsplash, Pexels, or Pixabay instead, where images are free to use. If you want to use a specific image you found elsewhere, search for its license or contact the creator to ask.

What do I do if my image looks blurry when I print it?

Your image was probably created at screen resolution (72 pixels per inch) instead of print resolution (300 pixels per inch). For next time, create your image at 300 DPI from the start. If you have already created it, you cannot fix blurriness by resizing it larger — you have to start over with the right dimensions.

Do I need to pay for Photoshop to create images?

No. GIMP, Pixlr, Photopea, and Canva are all free and work for most image creation tasks. Photoshop costs money but offers more advanced features. Start with a free tool and upgrade only if you find you need something it cannot do.

Can I create an image on my phone?

Yes. Canva, Pixlr, and Adobe Express all have phone apps. They work the same way as the computer versions and save your work to the cloud so you can access it from any device. Phone apps are best for quick social media posts and straightforward graphics.
