Each social media platform has specific recommended image dimensions. An Instagram post is 1080×1080 pixels, a Twitter/X header is 1500×500, a Facebook cover is 820×312, and a LinkedIn banner is 1584×396. Uploading images that don't match these dimensions results in awkward cropping, blurry scaling, or wasted visual real estate.
Manually remembering and entering exact pixel dimensions for each platform is tedious and error-prone. Convertful's presets give you one-click access to all major platform sizes — Instagram posts, stories, reels covers, Twitter headers, Facebook covers, LinkedIn banners, YouTube thumbnails, and more. Your images will look crisp and professional on every platform.
Select your target platform and format, then drop your image. Convertful resizes and/or crops the image to match the platform's recommended dimensions. You can choose between fit (letterbox with padding), fill (center crop), or stretch modes. Everything runs in your browser — no upload needed.
Completely. Your images are processed locally and never leave your device. No sign-up, no watermarks, no data collection.
