Canva

Since you are on a PC, the steps are actually a bit easier because you have more screen real estate to work with. Since Instagram’s "Create" mode is mostly restricted to the mobile app, Canva is your best bet on a computer. Here is the step-by-step for PC:Using Canva on a PC (Free) Go to Canva.com: Log in with a free account (Google or Facebook login works fast). Create a Design: Click the Create a design button in the top right corner and select Facebook Post (Square). This gives you a perfect $1080 \times 1080$ canvas. Choose a Background:Click the Background tab on the left sidebar (or click the white square and then the color palette icon at the top). Pick a solid color or a gradient. Add Your Text: * Press the 'T' key on your keyboard to instantly drop a text box onto the screen. Paste your long text into that box. Format for Readability:Resize: Grab the corners of the text box to stretch it.Font Size: Use the toolbar at the top to shrink the font until everything fits comfortably. Alignment: Use the alignment button to center the text or justify it. Download: * Click Share in the top right corner.Click Download.Keep the file type as PNG and click the purple Download button. The file will save to your "Downloads" folder. Post to Facebook: Go to Facebook in your browser, click "Photo/Video" in the post creator, and upload your new image. A "Pro" Tip for PC Users: Use Snipping ToolIf you find Canva too "fussy," there is an even faster "low-tech" way: Open a blank Word document or Google Doc. Change the page color to something bright (In Word: Design > Page Color). Type your text, make it Bold and Large (e.g., Size 24 or 30). Use the Snipping Tool (Press Windows Key + Shift + S) to draw a square around your text. Go to Facebook and simply Paste (Ctrl + V) directly into the "What's on your mind?" box. Facebook will treat the "snip" as an image. Which one should you choose? Use Canva if you want it to look "pretty" and professional with nice gradients. Use the Snipping Tool if you just want to get it done in 30 seconds.
