Image Cropping Guide

Crop Image to Square — 1:1, Ratios & Freeform

Lock a square crop or 1:1 crop for avatars and posts. Crop image by aspect ratio — including freeform and custom ratios — with on-device Canvas framing.

Lock square, 1:1, 4:3, 3:2, 16:9, 9:16, 5:4, freeform, or custom ratios on Canvas. Convert HEIC first; JPG/PNG/WebP crop natively.

Aspect-aware framing with golden ratio & rule of thirds

Profile pics and product thumbnails often need a clean square crop. Use this page to crop image to square, run a 1:1 crop, or crop image 1:1 for feeds that reject letterboxing. Prefer landscape narrative? Crop image to rectangle, or crop image by aspect ratio with familiar presets: crop image 4:3, crop image 3:2, crop image 16:9, crop image 9:16, and crop image 5:4. Need looser control? Crop image freeform or crop image with custom ratio when the brief is not a named preset. Composition still matters: place eyes on the rule of thirds intersections, and lean on golden-ratio spiral energy when portraits feel cramped inside the square. Native Canvas crop supports JPG/PNG/WebP; convert HEIC to PNG first when iPhone shots must become a square crop.

How it works

  1. 1

    Pick square or another ratio

    Choose square crop / 1:1 crop, or pick crop image 4:3, crop image 16:9, crop image 9:16, and other presets — or crop image freeform.

  2. 2

    Compose with thirds & golden ratio

    Slide the frame using rule of thirds and golden-ratio intuition so faces and products sit on strong lines while you crop image by aspect ratio.

  3. 3

    Export the locked ratio

    Download after you crop image to square or crop image with custom ratio. Convert HEIC first if needed; compress afterward if the file is still heavy.

Use cases

Avatar & profile squares

Square crop and crop image 1:1 for hubs, chat avatars, and app icons that demand equal sides.

Landscape & portrait slots

Crop image to rectangle with crop image 16:9 heroes or crop image 9:16 vertical stories.

Print-ish photo ratios

Crop image 3:2, crop image 4:3, and crop image 5:4 when legacy print ratios still guide the layout.

Custom brand frames

Crop image freeform and crop image with custom ratio when marketing defines a nonstandard box.

Problems we solve

Feeds refuse non-square uploads

Crop image to square or run a 1:1 crop before posting so platforms stop auto-zooming faces.

Subjects stuck in the dead center

Use rule of thirds and golden-ratio placement while you crop image by aspect ratio for more cinematic balance.

Wrong ratio for the destination

Switch from crop image 16:9 to crop image 9:16 (or freeform) instead of stretching pixels.

Trust, speed & privacy

Local Canvas privacy

Square crop and 1:1 crop run on Canvas locally — nothing uploaded for aspect locking.

Instant ratio switches

Flip between crop image 4:3, crop image 3:2, and other presets in seconds — no remote encode queue.

Windows, macOS, Android, iOS & Linux

Crop image to square on Windows, macOS, Android, iOS, and Linux browsers alike.
