Pro Tip: Always design at 2× the listed pixel size for retina/hi-DPI screens, then export at the correct size. Use PNG-24 for logos and graphics with text. Use JPG at 80% for photographs. Keep all important content within the centre 80% of the canvas, platforms crop edges on mobile.
Create artwork at double the final pixel size (e.g. 2160×2160 for a 1080×1080 post), then export at the target size. This ensures pixel-perfect sharpness on retina displays and avoids blurring.
Keep all critical text, logos and CTAs within the central 80% of the canvas. Profile pictures, UI buttons and navigation bars overlap edges on different devices and screen sizes.
Use PNG-24 for anything with text, logos or flat colour to prevent compression artefacts. Use JPG at 70 to 80% quality for photographs, you get smaller file sizes without visible quality loss.
Facebook, Instagram and LinkedIn aggressively compress images above 1MB. Optimise your exports to stay under this threshold for the best visual quality in the feed.
Common questions about this free tool, answered clearly.
The right size stops your images from being cropped, stretched or blurred. Each platform crops differently, so an image that looks great on Instagram can be cut off on LinkedIn.
Platforms adjust them every year or so. This guide is kept current for 2026, so check back when you plan a new campaign rather than trusting an old cheat sheet.
A 1080 by 1080 pixel square works across most feeds. A 1200 by 630 image works for shared links. When in doubt, keep important content in the centre so no crop cuts it off.
