Try this tip from Lincoln Design Co. on using Adobe Express to resize images and graphics for social media.
Click Social media from the Home page. Then hover over Instagram square post and select Browse templates.
Tip: Save your assets to a Creative Cloud Library. For best results, create image assets at the largest size for the collateral you’re designing.
Select Your stuff from the toolbar on the left, select Brands & Libraries, and find the library where you saved your assets. Drag individual assets onto your artboard and then resize and position them as needed.
Tip: For best results, use images with a minimum of 150dpi for digital projects and 300dpi for print projects.
Select the Text tool and click Add your text. Replace the default text and choose a font, color, and style. Lincoln uses a font similar toTrade Gothic Next LT Pro Heavy Condensed .
Tip: With text and imagery in place, you can now add effects or animations.
Choose the sizes for the platforms you’re posting to, and then click Duplicate & Resize.
Rearrange and scale the assets to fit each artboard. When you finish a layout, click the right or left arrows to move to the next one.
