Image Resizer

Upload your image, enter the desired width and height in pixels (or choose a social media preset), and click Apply. Download the resized image instantly, no software or signup needed, and nothing is uploaded to a server.

Yes. Drop several images together and the tool switches into batch mode, it resizes them all to the same box using your chosen settings, then lets you download every result as a single ZIP file. You can add more images to the batch or remove any before processing.

Choose JPG or WebP as the output format, switch the quality control to 'Target KB', and enter your limit (for example 100). The resizer automatically tunes the compression quality so the exported file lands just under that size, ideal for upload limits.

Instagram optimal sizes: Square post = 1080×1080px, Portrait = 1080×1350px, Story/Reel = 1080×1920px. Use the Instagram presets in the tool for automatic sizing.

Keep the 'Locked' aspect-ratio toggle on so width and height scale together. If you need an exact box that has a different shape, unlock the ratio and pick Fill (crop to cover the box), Fit (letterbox with a background color), or Stretch.

Yes. Crop mode lets you drag a selection box with aspect-ratio presets (1:1, 4:3, 16:9 and more), and the Transform controls rotate to any angle and flip horizontally or vertically before you export.

Resizing down (making smaller) generally maintains sharpness thanks to high-quality resampling. Resizing up (making larger than the original) introduces some blurriness because the tool has to invent pixel data that was never captured.

YouTube thumbnails should be 1280×720px (16:9 aspect ratio). File size must be under 2MB, use the YT Thumb preset, then switch to Target KB if you also need to stay under a size limit. JPG format works best for thumbnails.

Enter the target width and height in pixels (for example 1920x1080) and download. You can lock the aspect ratio to avoid stretching, or unlock it to force exact dimensions.

Switch to target-size mode and enter the KB you need; the tool adjusts dimensions and quality to land near that size, which is ideal for upload forms with strict limits. Resizing runs in your browser, so nothing is uploaded.

Common targets: Instagram post 1080x1080, Instagram story 1080x1920, YouTube thumbnail 1280x720, and LinkedIn banner 1584x396. Enter the dimensions you need and export at the right size for the platform.

Yes: lock the aspect ratio and the tool scales width and height together so the image keeps its proportions.
