Why use this?

25+ ready presets

Covers Instagram posts, stories, reels, YouTube thumbnails, channel art, TikTok, Twitter/X, LinkedIn, Facebook, Pinterest and more. No need to look up dimensions.

Smart crop vs Fit

Smart Crop fills the frame perfectly (may trim edges). Fit Inside shows the full image with letterboxing. Stretch forces exact dimensions โ€” use with care.

100% private, zero upload

Everything happens inside your browser using the Canvas API. Your image never touches a server. Works offline once the page is loaded.

WebP for smaller files

Choose WebP output to get images 25โ€“35% smaller than JPG at the same visual quality โ€” great when platform file size limits are tight.
