Lower quality settings can create smaller files. Actual results depend on the image and format.
WebP often produces smaller files. JPEG and WebP use lossy encoding; PNG is lossless.
Optional. Images wider than this value will be resized proportionally. Leave blank to keep their dimensions.
Your images stay in your browser while this tool processes them.
Your Compressed Images
Files are processed locally by this tool. They are not intentionally uploaded to a compression server.

Compress and Download
Start compression, compare the resulting file sizes, and download the optimized images to your device.
Smaller Images, More Efficient Websites
Large image files can increase the amount of data a website needs to load. Reducing image file size can help limit page weight, especially on image-heavy pages. The actual effect on loading speed depends on the website, image dimensions, caching, and other performance factors.
An online image compressor lets you choose a suitable format and quality level before using an image on a website, in a presentation, or in a digital project. For many photographic images, WebP or JPEG can provide a practical balance between file size and appearance.
For graphics that require transparency or pixel-perfect edges, compare the results carefully. PNG preserves image data without lossy compression, while lossy formats may reduce file size further at the cost of some detail.

Image Compressor FAQs
Helpful answers about image compression, formats, quality, and privacy.
What is an Image Compressor?
An Image Compressor reduces the file size of an image by using compression and, when selected, smaller image dimensions. The result depends on the image content, format, and quality settings.
Can I compress images online for free?
Yes. You can use this free image compression tool to select supported images, adjust settings, process them in your browser, and download the results without creating an account.
Which image formats are supported?
The tool accepts JPEG, PNG, and WebP image files. You can retain the original format or choose WebP, JPEG, or PNG as the output format.
Will compression reduce image quality?
Lossy compression can remove image data, so some quality reduction may occur. A higher quality setting generally preserves more detail but may produce a larger file. Results vary by image and format.
Can I compress PNG images?
Yes. PNG images are supported. PNG output uses lossless encoding, so the quality slider does not control PNG compression in the same way as JPEG or WebP. Converting a PNG to JPEG or WebP may reduce file size, but transparency may be lost.
Are my images uploaded to a server?
This tool processes the selected image data locally in your browser using the Canvas API. The compression code does not intentionally upload your image files to a remote compression server.
How can I make an image file smaller?
Select a suitable output format, reduce the quality setting when appropriate, or lower the maximum image width. Compare the final file size and image appearance before using the result.
