Why image sizes matter so much
Every social media platform has its own requirements for image sizes and formats. Wrongly dimensioned images get cropped, look blurry, or are padded with black bars. That looks unprofessional and reduces the interaction rate.
With our social media resizer you can crop images to all platform sizes right in the browser — free and without upload.
General tips
- Always export at highest quality — platforms compress again themselves
- RGB instead of CMYK — social media only displays RGB correctly
- JPG for photos, PNG for graphics with text — text in JPGs often gets blurry
- Mind the safe zone — keep important content 10–15% from the edge (often cropped)
- Follow platform updates — sizes change occasionally
