Best 7 Photo Resizers in 2026: Compare Key Features

Introduction

Choosing a photo resizer depends on what you need to change: pixel dimensions, file size, or a specific print size. This roundup compares seven Android and iOS apps, with options for batch resizing, cropping, and other image adjustments. The right fit comes down to your device and the task at hand.

Quick comparison table

The apps cover a range of jobs, from setting print measurements to reducing file sizes or resizing several photos at once. Some include cropping, image-quality adjustments, or support for multiple formats. Prices are listed as unknown because the information provided for these apps does not specify them.

1. Image Size - Photo Resizer

Best for: Precise physical or pixel measurements.

For a specific print size or exact dimensions, Image Size - Photo Resizer lets you enter measurements in several ways. It supports pixels, millimeters, centimeters, and inches, so you can use familiar units instead of converting them yourself.

You can also crop or rotate an image if it needs a different frame or orientation. The app lets you save or share the finished result, making it a useful Android option when you need to prepare an image to specific measurements.

2. Resize Image

Best for: Straightforward resizing on iPhone.

Resize Image makes size adjustments simple: enter a value or use the slider. You can work in pixels or percentages, whether you need exact dimensions or just want to make an image smaller.

Aspect-ratio controls and size presets are handy additions. Keeping the ratio consistent helps prevent stretching, and presets save time if you often resize photos to the same dimensions. It’s a practical iOS option for direct controls and a simple workflow.

3. Photo Resizer: Crop, Resize, S

Best for: Batch resizing on Android.

For a group of photos, Photo Resizer: Crop, Resize, S can resize or crop by pixels, percentages, or proportions. You can set an exact output size or adjust images relative to their original dimensions.

Batch resizing is the main draw: process several images in one job instead of repeating the same steps for each photo. You can also share the resized results, which is useful if they’re going straight to another app or recipient. Consider it when handling multiple photos matters more than print-unit controls.

4. Photo Resizer - Resize & Crop

Best for: Presets alongside custom dimensions.

Photo Resizer - Resize & Crop offers preset sizes as well as custom dimensions. Presets suit common resizing tasks, while custom values help when a website, form, or project calls for exact measurements.

You can crop and resize in the same app, and it supports processing multiple images. That’s useful if you want to frame photos without switching tools. Its main advantage is the choice between a quick preset and a size you enter yourself.

5. Resize image size in kb & mb

Best for: Managing image dimensions and file size.

When an upload has a file-size limit, Resize image size in kb & mb offers more than pixel adjustments. It can resize, crop, and compress images, with controls for dimensions and file size.

The app supports JPG, PNG, and WEBP, which helps if you need to keep an image in a particular format. Remember that changing dimensions and compressing a file are separate adjustments. Check the exported image to make sure it meets the limit without losing more quality than you’re comfortable with.

6. Photo Resizer: resize image

Best for: Resolution changes and JPEG file-size reduction.

Photo Resizer: resize image lets Android users resize by resolution or percentage. Use the percentage option to shrink an image proportionally, or set a resolution when you need particular pixel dimensions.

The app can also reduce JPEG file size, which may help a photo meet an upload limit. It supports JPG, PNG, and WEBP images, but its described file-size reduction focuses specifically on JPEG. If you have a strict limit, check the saved file before sharing it.

7. ImageResize - Photo Resizer

Best for: iPhone users who want quality and metadata controls.

ImageResize - Photo Resizer can change dimensions, adjust image quality, convert formats, crop, and rotate photos. It suits iPhone users who want several basic image-editing options in one app.

Metadata management sets it apart. Metadata is information attached to an image, and controls for it can be useful when preparing a photo to share or handle. If you only need a simple resize, another app may be more direct. Choose this one if quality or metadata adjustments matter too.

How we picked these apps

We selected apps based on the resizing controls and practical options described for each one. We looked for ways to set pixel dimensions, work with percentages or proportions, use physical measurement units, and manage file-size limits. Not every app is designed for the same task.

The list includes Android and iOS apps for both single-image edits and batch resizing. Some also offer compression, JPEG size reduction, cropping, presets, multiple image formats, or image-quality and metadata controls.

Each app is matched to a particular use case rather than ranked on every feature. Preparing a print calls for different tools than shrinking a file for an upload. Check the “Best for” notes, then make sure the app’s controls suit the output you need.

Frequently asked questions

What does a photo resizer change?

Resizing changes an image’s pixel dimensions, which can affect its sharpness or detail, especially if you enlarge it. Dimensions and file size are different: compression can reduce the storage an image uses without changing its pixel width and height.

How do I resize a photo without changing its proportions?

Use aspect-ratio controls to preserve the relationship between width and height and help prevent stretching. Cropping changes the visible framing, while resizing changes the image’s dimensions. Check the result to make sure it hasn’t been stretched or cropped unexpectedly.

Which photo resizer should I choose for a file-size limit?

Look for an app with explicit file-size controls or JPEG size reduction, such as Resize image size in kb & mb or Photo Resizer: resize image. Format and image quality can affect the final file size, so check the exported image before uploading or sharing it.

The verdict

The right choice depends on your task and device. Image Size - Photo Resizer supports pixel and physical measurement units, cropping, rotation, and sharing. For Android batch jobs, Photo Resizer: Crop, Resize, S can handle several images at once. On iPhone, Resize Image offers pixel, percentage, and aspect-ratio controls. If file size is your main concern, consider one of the apps with file-size controls or JPEG reduction.
