About iResize

iResize is a free collection of everyday file tools — resizing, compressing, converting and editing images, working with animated GIFs, creating icons and favicons, picking colours, and converting PDFs. There's nothing to install and no account to create.

Private by design

Most online tools upload your files to a server. We don't. Every tool here runs entirely in your browser using the Canvas API and WebAssembly, so your images and documents never leave your device. That makes the tools fast, works offline once loaded, and means your files stay completely private.

What's included

The site currently offers 11 tools:

  • Image Resizer — Resize images by pixels or percentage with one-click downloads.
  • Bulk Image Resizer — Resize many images at once and download them all as a ZIP.
  • Image Compressor — Shrink image file size by quality or a target size in KB.
  • Image Converter — Convert between PNG, JPG, WebP and HEIC formats.
  • Image Editor — Crop, rotate, flip and tweak images in your browser.
  • GIF Resizer — Resize animated GIFs while keeping every frame.
