How to resize images without uploading them

Learn why client-side resizing keeps your photos private and how to pick the right dimensions for web, print, and social platforms.

Most image tools upload your files to a remote server before processing them. pix-8 runs entirely in your browser — your photos never leave your device.

When to resize

  • Web & email: Keep widths between 1200–1920px for sharp display without bloated file sizes.
  • Thumbnails: 400px on the long edge is usually enough for cards and previews.
  • Print: Match pixel dimensions to your target DPI (e.g. 300 DPI for a 6×4 inch print ≈ 1800×1200px).

Tips for the Resizer tool

  1. Upload your source image.
  2. Enter target width and height — lock aspect ratio when scaling proportionally.
  3. Enable Privacy Mode to strip EXIF metadata from the exported file.
  4. Download the result instantly.

Resizing locally means faster iteration, zero queue time, and complete control over your files.
