Cropping doesn't touch pixel quality — it just selects a smaller region of the same image. The part that trips people up is aspect ratio: Instagram, YouTube, and website banners each expect different proportions, and cropping freehand rarely lands on them exactly.

Common aspect ratios

  • 1:1 (square): Instagram feed posts, profile photos.
  • 4:5 (portrait): Instagram feed posts optimized for mobile screen space.
  • 9:16 (vertical): Instagram/Facebook/TikTok Stories and Reels.
  • 16:9 (widescreen): YouTube thumbnails, website hero banners, presentation slides.

How to crop an image

  1. Upload: Drag and drop a JPG, PNG, or WebP file.
  2. Pick a ratio: Use a preset (1:1, 4:5, 9:16, 16:9) or select "Free" for a custom crop.
  3. Frame the shot: Zoom and drag to position the crop area.
  4. Download: Save the cropped image in your chosen format.

Frequently Asked Questions

Which aspect ratio should I use for Instagram vs a website banner?

Instagram feed posts use 1:1 (square) or 4:5 (portrait); Instagram/Facebook Stories use 9:16; YouTube thumbnails and most website hero banners use 16:9. Use the preset buttons instead of guessing pixel dimensions.

Does cropping reduce image quality?

Cropping itself doesn't degrade quality — you're just selecting a smaller region of the same pixels. Quality loss only happens if you also re-compress the output at a low JPG quality setting.

What formats does the cropper support?

JPG, PNG, and WebP, both as input and output.

Is it safe to use this browser-based tool?

Yes. Cropping happens locally in your browser — images are never uploaded to a server.
