Frequently Asked Questions
Which platforms are supported?
Instagram, Facebook, X/Twitter, YouTube, LinkedIn, TikTok, Pinterest and WhatsApp — each with its official recommended sizes.
What is the difference between crop-to-fill and fit?
Crop-to-fill makes the image exactly the target size by trimming the edges. Fit shows the whole image and fills the rest with a background color.
Why do my photos look blurry on social media?
Most platforms down-scale or crop images that don't match their recommended sizes. Using the exact preset keeps your image sharp.
Are my images uploaded when I resize?
No — the whole process runs locally in your browser.
How this tool works
Every social network displays images at its own recommended sizes, and posting a photo in the wrong dimensions makes it blurry, cropped or compressed by the platform.
- Pick the platform, choose the format (post, story, cover, thumbnail, profile...) and the tool resizes your photo to that exact dimension. Crop-to-fill trims to the frame; fit shows the whole image with a background color you choose.
- Everything is rendered locally on a canvas, so your original never leaves your device and what you see in the preview is exactly what you download.
Why correct sizes win
Instagram, Facebook and the rest auto-compress anything that isn't the right shape. A well-sized image stays sharp, loads fast and gets more engagement — square posts, for example, dominate Instagram feeds.
Preparing even a handful of posts at the right sizes keeps your feed consistent, your brand professional and your thumbnails click-worthy.
Pro tip: When the aspect ratio differs a lot from your photo, crop-to-fill usually looks cleaner than fit with large background bars — but fit is ideal for vertical stories.
