About Image Resizer

Free online image resizer that runs locally (no uploads). Resize images in batch — change dimensions for social media, thumbnails, and forms quickly and privately.

How it works

  1. 1 Add images (drag & drop or select).
  2. 2 Set Max Dimension or specific width/height, and choose Resize Mode (Fit/Fill/Exact).
  3. 3 Optional: keep aspect ratio and disable upscaling to avoid blur.
  4. 4 Download resized images (ZIP for multiple files).

Tips

  • Common sizes: 1080×1080 (square), 1080×1350 (portrait), 1200×630 (OG), 1920×1080 (HD).
  • Use Fit to avoid cropping; use Fill when you want full coverage (may crop edges).
  • Avoid upscaling small images — it can look blurry.
  • After resizing, run Image Compressor to reduce file size further.

FAQ

Are files uploaded to a server?

No. Resizing happens locally in your browser.

Can I resize multiple images at once?

Yes. This tool supports batch resizing.

Will resizing reduce quality?

Resizing changes pixel dimensions. Quality loss mainly depends on the output format and compression settings.

How do I keep the aspect ratio?

Enable Keep Aspect Ratio (or use Fit mode) to prevent distortion.
