Why this tool
Resize images for every social preset
Every network crops differently. A square that looks fine on Instagram feed can look wrong as a Reel cover or YouTube thumb. Resizing before upload saves rejected uploads and blurry posts.
Choose a preset, preview the canvas result, and download. Processing stays in your browser. There is also a quick size table so you can brief a designer without guessing pixels.
Use sharp product mockups in your ownstreet listings so buyers in India trust what they purchase with UPI on mobile.
