Best 8 Image Compressors in 2026: Compare Features & Formats

Introduction

This roundup compares eight iOS and Android apps for compressing images. Their stated features include batch processing, resizing, and format conversion, with some apps also handling video or audio. We’ve focused on the practical differences described in each app’s listing, including whether processing happens on-device or works offline.

Quick comparison

Features and processing details come from app store descriptions and may change between versions. Prices are marked unknown because they aren’t specified in the supplied details.

1. Image Compress Photo & Video

Best for: iPhone users who want to compress photos and videos in one app.

Image Compress Photo & Video handles two common types of large media files: photos and videos. Its listing says you can compress photos in batches, and that processing happens on-device.

Batch photo compression is useful when you have several images to prepare. Video support also makes this more flexible than a photo-only compressor. Check the current listing for details on settings and compatibility.

2. Photo Compressor: AI Cleaner

Best for: iPhone users who want to compress several types of media.

Photo Compressor: AI Cleaner is described as handling photos, videos, and audio, with batch processing and image-resizing options. The listing also says processing happens on-device.

Its broad media support is the main reason to consider it: you can use one app for more than photos. Resizing can help when you need to change an image’s dimensions as well as reduce its file size. The on-device claim is worth noting, but check the current app details and settings if privacy is a concern.

3. Photo Compressor: Save Space

Best for: iPhone users who want batch compression and support for common image formats.

Photo Compressor: Save Space compresses images and supports batch processing. Its listing names JPEG, PNG, and HEIC/HEIF, including formats commonly associated with Apple devices.

That range of formats is its clearest distinction. It may be useful if you work with different image types instead of compressing just one format. The app description confirms format support, but doesn’t say whether every format can be exported with every compression setting. Check the options in the current version.

4. Image Resizer & Compressor

Best for: Android users who want compression, resizing, and format conversion in one app.

Image Resizer & Compressor combines image compression and resizing with batch processing. Its listing also describes conversion between formats such as JPG, PNG, and WebP.

The app brings together three practical tasks: reducing file size, changing dimensions, and converting formats. Its listing covers a broad set of image tools, but can’t show how a particular photo will look after processing. Check the current format and export options before converting a batch.

5. JPEG Image Compressor & Resize

Best for: Android users who want control over JPEG/JPG output size.

The standout feature of JPEG Image Compressor & Resize is the option to target a file size. Its listing also describes bulk compression and resizing for JPEG/JPG images.

A target size can help when a website, form, or messaging service has a file limit. It gives you a specific goal instead of asking you to judge compression by appearance alone. The listing confirms the feature, but doesn’t say how closely every image will meet the chosen size while retaining detail. Review the results before using them.

6. Photo Compressor and Resizer

Best for: Android users who want to set an output file size or resolution.

Photo Compressor and Resizer compresses and resizes photos, and its listing says it supports batch compression. It also describes options for setting a file size or resolution.

Those options give you two ways to make an image smaller: limit its storage use or change its pixel dimensions. Resizing changes the image’s dimensions, while compression affects its file size. If you process several photos at once, check each finished file to make sure the setting worked well for it.

7. Photo Compressor & Resizer

Best for: Android users who want to compress photos without an internet connection.

Photo Compressor & Resizer is described as supporting photo compression, resizing, and batch processing. Its listing also says it works offline.

Offline use may be handy when you don’t have internet access or don’t want the task to depend on a connection. The listing makes a claim about offline operation, but doesn’t give broader details about data handling or whether every feature works without a connection. Check the app’s current settings and test it before relying on it away from a network.

8. Image Compressor: Resize Photo

Best for: Android users who want compression along with basic resizing and editing.

Image Compressor: Resize Photo handles one or multiple images and includes resizing and editing features. It may suit someone looking for a few basic image tools alongside file-size reduction.

The combination of compression and editing sets it apart from apps focused mainly on reducing file size. You can work with one photo or several, then use the resizing and editing options as needed. The supplied listing details don’t specify supported formats or explain the editing tools in depth, so check the current app page if you need a particular format or edit.

How we picked these apps

We selected apps whose store descriptions clearly state that they include image-compression features. The comparison looks at practical differences such as batch support, resizing, target file size, format support, and whether an app also handles video or audio.

We include privacy and connectivity claims only when the supplied descriptions specifically say processing happens on-device or that the app works offline. These statements don’t replace checking the app’s current settings and privacy information.

An app name or marketing phrase doesn’t prove image quality, compression performance, or how a particular photo will look afterward. Before installing, check the current store listing for pricing, device compatibility, supported formats, and feature changes.

Frequently asked questions

What does an image compressor do?

An image compressor reduces the storage space a file uses, often by changing how its data is encoded. Resizing is different: it changes the image’s pixel dimensions, though a smaller image may also have a smaller file size.

What is the difference between lossy and lossless compression?

Lossy compression can reduce a file more by discarding some image detail, which may affect how it looks. Lossless compression keeps the original image data but may reduce the file by less. The options depend on the image format and app. Keep an original copy when testing settings on important photos.

Is batch compression worth using?

Batch compression can save time when you need to process several images instead of choosing settings for each file separately. Review the results before sharing them or deleting originals, especially if you’ve set a target size or used strong compression. Format support and privacy details vary by app and its current settings.

The verdict

The apps take different approaches to image compression. Image Resizer & Compressor lists batch compression, resizing, and JPG, PNG, and WebP conversion. JPEG Image Compressor & Resize offers a target file-size option, while Photo Compressor & Resizer is described as working offline. Choose based on your device, preferred formats, and whether you need batch processing or resizing. No single image compressor will suit everyone.
