These are the dimensions FreeImageKit's presets use, and you can resize a whole batch to any of them in your browser.
Steps
- Open the Social Media Image Resizer, or Resize Image to Common Dimensions for web and avatar sizes.
- Select your images and choose a preset such as Instagram portrait or YouTube thumbnail.
- Resize and download the files, or a ZIP of all of them.
Why exact sizes matter
Feeds crop to a fixed aspect ratio and recompress large uploads. Exporting at the platform's expected ratio keeps your subject in frame and avoids a second round of quality loss.
Specs change
Platforms update recommended sizes and file limits without warning. Treat this table as a reliable starting point and confirm against the platform's current help page for anything business-critical.
Website images
A width of 1920 px covers full-width layouts on most laptop and desktop screens. WordPress scales down uploads larger than 2560 px, and Shopify recommends square 2048 × 2048 px product images. Resize before upload, then compress.

Frequently asked questions
What size should an Instagram post be?
FreeImageKit's presets use 1080 × 1080 px for a square post and 1080 × 1350 px for a 4:5 portrait post, which takes the most feed space.
What size is a YouTube thumbnail?
1280 × 720 px (16:9), kept under 2 MB. The YouTube Thumbnails workflow crops to that size and picks a JPG quality that stays under the limit.
Can I resize many images at once?
Yes. The resizers accept batches and give you a ZIP, and nothing is uploaded.
