RapidHow to Crop an Image on Android Free — 3 Easy Ways
Crop any photo using Google Photos, Samsung Gallery, or a browser tool with ratio presets such as 4:5 — all free on any Android phone.
How to crop an image on Android is free with Google Photos — already installed on most Android phones. For Samsung Galaxy users there is also a built-in option in the Samsung Gallery app. For extra ratio presets such as 4:5, a browser tool in Chrome handles it without any download.
Method 1: Google Photos (Pre-Installed on Most Android Phones)
Google Photos is the fastest option and works on virtually every Android phone running Android 6 or later.
- Open Google Photos and tap the image you want to crop.
- Tap the Edit icon (the slider icon at the bottom of the screen).
- Tap Crop in the edit toolbar.
- Tap the aspect ratio icon (top-right of the crop screen) to choose a preset — Free, Square, 4:3, 16:9, and others.
- Drag the crop handles or drag inside the frame to reposition.
- Tap Save copy to keep the original and save a new cropped version.
Method 2: Samsung Gallery (Samsung Galaxy Phones)
Samsung Galaxy phones include a built-in gallery app with its own crop tool that works offline.
- Open the Gallery app and tap the photo.
- Tap the pencil (Edit) icon at the bottom.
- Tap Crop and transform (the crop icon in the edit toolbar).
- Drag the corners to set your crop area, or tap the aspect ratio icon to pick a preset.
- Tap Save when done. Samsung Gallery saves a copy and keeps the original.
Method 3: Browser Tool — Ratio Presets, Including 4:5 (Chrome on Android)
Neither Google Photos nor Samsung Gallery lets you specify exact pixel dimensions. The browser tool gives you ratio presets (Square 1:1, Portrait 4:5, 16:9 and more) and shows the selection size in pixels as you drag. It does not have a box to type an exact size either, so if you need a precise size — for example 600×600 for a passport photo or 1080×1080 for Instagram — crop to the right ratio first, then set the exact pixels with Resize Image.
- Open Chrome on your Android phone and go to rapidtools.online/crop-image.
- Tap Upload and select the photo from your gallery.
- Pick an aspect ratio preset (such as Square 1:1 or Portrait 4:5), or use Free Form and drag the corners. The selection size is shown in pixels as you drag.
- Drag to position the crop frame.
- Tap Apply Crop, then Download Cropped Image — the file saves to your Downloads folder.
- Need an exact pixel size? Open Resize Image, upload the cropped image, and enter the width and height you need.

Frequently Asked Questions
How do I crop an image on Android for free?
Open Google Photos, tap the photo, tap Edit (slider icon), then tap Crop. Choose an aspect ratio or drag the corners freely, then tap Save copy. Pre-installed on most Android phones — no download needed.
How do I crop to a 1:1 square on Android?
In Google Photos: Edit → Crop → tap the aspect ratio icon → Square or 1:1. Adjust the frame, then tap Save copy. For exact 1080×1080 pixels, set the size afterwards with rapidtools.online/resize-image in Chrome.
What is the difference between Save and Save copy in Google Photos?
Save copy creates a new separate image and leaves the original untouched. Save (or Done in some versions) applies the edit to the existing photo but keeps the original recoverable via Edit → Undo. Save copy is safer when you want to keep both versions.
Can I crop to exact pixel dimensions on Android?
Not in one step. Google Photos and Samsung Gallery crop by ratio only. For exact pixels, crop to the right ratio first (in your gallery app or at rapidtools.online/crop-image in Chrome), then open rapidtools.online/resize-image and enter your target width and height.
How do I crop a photo on a Samsung Galaxy?
Open Gallery, tap the photo, tap the pencil icon, then tap Crop and transform. Drag the handles or pick a ratio preset, then tap Save. Built into all Samsung Galaxy phones and works without internet.
