Image Size Checker & Resizer by PiCraft

Check an image against YouTube, LinkedIn, Pinterest and Amazon specs, then resize, crop and compress it to fit. Runs locally.

Find out if an image meets a platform's rules before you upload it, then fix it in one click. Drop in an image (or right-click any image on the web) and see a clear pass / check / fix result for: • YouTube – video thumbnails and Shorts thumbnails • LinkedIn – profile cover and Company Page cover • Pinterest – standard Pins and full-screen Pins • Amazon – product listing main image (white background, size, zoom) • Kindle – eBook cover For every platform you see each requirement, what your image actually has, and why it matters. Then fix it: • Resize to the exact pixel size • Fill the frame (drag to choose the crop) or fit the whole image on a colour you pick • JPG or PNG output, with JPG quality tuned to stay under the platform's file-size limit • Download the result instantly Private by design: everything happens in your browser. Images are never uploaded and the extension collects no data. Limits were checked against each platform's own help pages in October 2026 and can change; the source of every rule is linked in the tool. Made by PiCraft (picraft.ai).
