100% private — resizing runs in your browser only.

How to Resize an Image

  1. Choose your image — click the box or drag and drop.
  2. Enter width and height in pixels, or pick a preset (Instagram, Full HD, story…).
  3. Keep "Lock aspect ratio" checked to avoid stretching — the other dimension adjusts automatically.
  4. Click Resize, review the preview, and download.

Want a smaller file size at the same dimensions instead? Use the Image Compressor. Need a document? Try Images to PDF.

Frequently Asked Questions

Will resizing reduce my image quality?
Making an image smaller keeps it sharp. Enlarging beyond the original dimensions can't add detail and may look soft — for best results, resize down rather than up.
Is my image uploaded to a server?
No. Resizing happens entirely in your browser using the HTML5 Canvas API. Your image never leaves your device.
What are common image sizes?
Popular sizes: 1920×1080 (Full HD), 1280×720 (HD), 1080×1080 (Instagram post), 1080×1920 (story/reel), 1200×630 (social link preview) and 851×315 (Facebook cover). All are available as presets above.
