Part of the Zerocoder platform

One tool of a platform where AI generates websites, images, video, text and documents — under one subscription.

Every platform wants its own size: a 1080×1080 post, a 1080×1920 story, a 1280×720 video cover, a 1200×630 link preview. Upload an arbitrary frame and the network crops it for you — badly. This tool resizes precisely and predictably: one side means proportional scaling, two sides mean a clean centre crop. Runs free on Zerocoder's servers. Afterwards, compress the file; for custom framing there's crop, for clean enlargement — upscale. The rest of the free tools are here.

Social media sizes: presets that stay current

The presets cover the core formats: square post, vertical story, wide video cover and link preview for messengers. Pick a preset — width and height fill in automatically, one click does the rest. Publishing daily? Bookmark the page: a week's batch of cards takes a couple of minutes.

Downscale to exact pixels without stretching

The classic mistake is stretching a frame to fit, which yields mush and distorted proportions. This tool never stretches: one given side means the other is calculated proportionally; two sides mean the excess is trimmed from the centre. Faces and objects stay natural.

Enlarging small images is a different job

Downscaling loses nothing that matters, but enlarging stretches existing pixels and blurs the image. If you need to go bigger, run the file through image upscaling: the Lanczos algorithm lifts resolution up to 2× noticeably cleaner than plain stretching.
