Social Media Image Resizer
Every platform crops uploads to its own sizes, and guessing costs you the edges of your design. Pick the platform and placement — Instagram portrait post, YouTube thumbnail, LinkedIn background, Etsy listing — and this tool produces exactly the published pixel size, either cover-cropped to fill the frame or contained on a background colour of your choice.
The preset library covers 17 platforms and is reviewed against the platforms' own documentation (review date shown in the tool). Platforms change specs occasionally, so treat the numbers as the best documented starting point — every preset states its size openly before you commit.

Sizes are the published recommendations of each platform, reviewed 2026-11-13. Platforms occasionally change them — the numbers here are a reliable starting point, not a guarantee.

Frequently asked questions
Cover or Contain — which should I choose?
Cover fills the entire frame and crops whatever does not fit — best for photos where the centre matters. Contain shows the whole image with background bars — best for graphics, logos and anything with text near the edges that must not be cut.
Why do platforms compress my upload anyway?
Platforms re-encode everything to their own pipeline. Uploading at exactly their published size (and avoiding a second resize on their side) keeps the result closest to your original.
Are these sizes guaranteed current?
They were reviewed against platform documentation on the date shown in the tool. Platforms do change specs without notice; when one does, the manual Image Resizer accepts any custom size.
