Online Image Compression Tool
This online image compression tool supports batch processing for JPG, JPEG, PNG, and WebP images. Keep the original format or output JPG, PNG, or WebP, then reduce file size with quality and maximum dimension settings. It is useful for website images, social media graphics, product photos, design assets, and local image organization. Files are processed in the browser without uploading them to a server.
How to compress images
- Upload one or more JPG, JPEG, PNG, or WebP images, or drag files into the upload area.
- Choose an output format and adjust compression quality. Enter a maximum width or height when you also want to reduce dimensions.
- Start batch processing and review the dimensions and file sizes before and after compression.
- Download successful images individually or package all results into one ZIP download.
Image compression settings
Keep original format when you want to reduce size without changing the file type. JPG works well for photos and web graphics, PNG is suitable for images that need transparency, and WebP is useful for modern websites. Lower quality usually creates smaller files but may reduce detail. When a maximum width or height is entered, the image is scaled proportionally without distortion.
Benefits of online image compression
The tool combines batch image compression, output format selection, quality control, and dimension limits. It shows file information for the original and result so you can compare the effect. Images are processed locally in the current browser, which is useful for private photos, product assets, and design files that should not be uploaded.
Frequently asked questions
Will the compressed image always be smaller?
The result depends on the original format, file size, image content, output format, and quality setting. An image that is already highly compressed may not become much smaller.
Will PNG transparency be preserved?
PNG transparency is preserved when you keep the original format or choose PNG output. JPG does not support transparency, so transparent areas are handled according to the JPG encoding format.
Are images uploaded to a server?
Image compression is performed in the current browser, and the compression feature does not actively upload images. You should still consider browser permissions and your network environment for your privacy requirements.
