What Is an Image Compressor?
An image compressor helps reduce the file size of an image. Smaller image files can be easier to store, share and use on websites.
This ToolStrive compressor lets you adjust the output quality and convert the selected image to JPG, WebP or PNG.
How to Compress an Image
- Select a JPG, PNG or WebP image.
- Choose the desired image quality.
- Select an output format.
- Click Compress Image.
- Compare the original and output file sizes.
- Download the result if you want to keep it.
Choosing Image Quality
Lower quality settings can produce smaller JPG and WebP files, but using a very low setting may introduce visible compression artifacts.
A higher quality setting generally preserves more visual detail but can result in a larger file.
The best setting depends on the image and how you plan to use it. Comparing the preview and output size can help you choose an appropriate balance.
JPG, WebP and PNG
JPG
JPG is commonly used for photographs and other images containing many colors. It uses lossy compression and does not preserve transparency.
WebP
WebP is a modern image format that can provide efficient compression and supports transparency in compatible browsers.
PNG
PNG is useful when lossless image data or transparency is important. Changing the quality slider does not provide the same lossy quality control for PNG that it provides for JPG or WebP.
Format Conversion and Compression
If you mainly need to change a JPG, PNG or WebP file into another format, use the Image Format Converter. Converting format and compressing are related but different tasks: conversion changes the encoding format, while compression focuses on reducing file size.
