About Image Resizer, Cropper & Rotator

The Image Resizer, Cropper & Rotator is a free in-browser image editor that lets you resize an image to exact pixel dimensions (with optional locked aspect ratio), crop it to preset ratios like 1:1, 16:9 or 9:16, and rotate or flip it, then export as PNG, JPEG or WebP. It is built on the browser Canvas API, so every edit runs on your device — your photo is never uploaded to a server. Reach for it when you need a quick profile picture, a social-media-sized crop, or a smaller copy of a photo without installing software.

How to use Image Resizer, Cropper & Rotator

  1. Drop an image onto the upload zone or click to browse — PNG, JPEG, WebP and GIF are accepted, and the file stays on your device.
  2. Pick a mode at the top: Resize, Crop, or Rotate / Flip. The live preview updates as you work, on a checkerboard so you can see transparency.
  3. In Resize, type a new Width or Height in pixels (keep Lock aspect ratio on to scale proportionally) or tap a Quick scale button — 25%, 50%, 75% or 100%.
  4. In Crop, choose an aspect preset (Free, 1:1, 4:3, 16:9, 3:2, 9:16, Instagram 1:1 or Story 9:16) and drag the box or its corners over the rule-of-thirds guides; in Rotate / Flip, rotate left or right 90° or flip horizontally/vertically.
  5. Choose an output Format (PNG, JPEG or WebP); for JPEG or WebP drag the Quality slider while watching the live estimated file size.
  6. Click Download to save the edited image — the whole pipeline ran locally in your browser.

Frequently asked questions

Are my images uploaded anywhere?
No. The tool decodes, crops, resizes, rotates and re-encodes your image entirely in your browser using the Canvas API. Nothing is sent to a server, so even sensitive or personal photos never leave your device.
Which formats can I open and export?
You can open PNG, JPEG, WebP and GIF images, and export to PNG, JPEG or WebP. PNG keeps transparency; JPEG and WebP add a quality slider so you can trade size against detail.
Why did the transparent parts of my image turn white?
JPEG has no transparency channel, so any transparent areas are filled with white on export. If you need to keep transparency, export as PNG or WebP instead.
Will resizing or rotating reduce the quality of my photo?
Resizing uses high-quality smoothing, and rotating in 90° steps and flipping are lossless geometric transforms. Quality only drops if you export to JPEG or a low WebP quality, or scale a small image up beyond its original pixels.
Is there a maximum image size?
Each output edge is capped at 8192px to keep browser memory predictable, and very large files or pixel dimensions are rejected with a message. Most phone and camera photos are comfortably within these limits.
Do phone photos load sideways?
No. The tool reads EXIF orientation when loading, so photos taken on a phone appear upright before you start editing.
