Does resizing happen on a server?

No. Images are resized in your browser with high-quality step-down scaling for crisp results. Nothing is uploaded.

Will resizing keep the aspect ratio?

Yes by default. Enable “maintain aspect ratio” to fit within your target box without distortion, or turn it off to force an exact width and height.

Are there presets for social media?

Yes. There are presets for Instagram, Facebook, X/Twitter, YouTube and LinkedIn, plus common web, avatar and thumbnail sizes.

Can I enlarge images?

Yes, though enlarging cannot add detail that is not there. Downscaling produces the sharpest results.

Can I resize images in bulk?

Yes. Resize many images at once and download them together as a ZIP.

Resize images for Twitter / X

Resize images for Twitter/X — including the 1500×500 header — with presets that avoid awkward cropping. Everything runs in your browser.

Privacy-first: every image is processed locally in your browser. Nothing is uploaded, stored or transmitted to any server.

Headers, avatars and the overlap problem

X/Twitter headers are 1500×500, and like LinkedIn, the profile picture overlaps the header’s bottom-left — leave that corner visually quiet. In-feed images preview close to 16:9; 1600×900 keeps them sharp without oversized files.

Control the crop before X does

Feed previews crop unpredictably around the center. Resizing to the target ratio yourself — Fill to crop deliberately, Fit to pad with color or blur — means the preview your followers see is the one you designed. The live preview shows the exact output, and nothing is uploaded during resizing.
