How to compress images online
This free image compressor opens selected images in your browser and exports new files at your chosen quality and dimensions. No account is required, and the tool does not upload selected images to an image-processing server. Very large images may use significant memory on your device.
1. Select your images
Choose one or more JPG, PNG, or WebP images, or drag them into the upload area.
2. Adjust quality and dimensions
Start around 75% quality, then compare the output and file size. Keep the original width or choose a maximum width of 1920, 1280, or 800 pixels.
3. Choose a format and download
Export as JPG for broad compatibility or WebP to try a modern format that often produces smaller files. Compression will not reduce every file because some images are already optimized.
Which image format should you choose?
PNG
Useful for screenshots, graphics, and transparent images. Exporting as JPG turns transparent areas white.
Read the compression guide →WebP
A modern format that can offer good visual quality at smaller file sizes. Check that your destination supports it.

Frequently asked questions
Are my images uploaded to a server?
No image file is sent to an image-processing server by this tool. Image decoding and export happen locally in your browser.
Will image quality change?
JPG and WebP use lossy compression with the settings provided here, so a smaller file can involve some visual change. Compare the output before replacing your original.
Will every image become smaller?
No. Results depend on the source file, dimensions, format, and quality. The tool shows before-and-after sizes.
Can I compress multiple images at once?
Yes, select multiple supported images in one batch. If your browser slows down, try a smaller batch.
Why does a transparent image have a white background?
JPG does not support transparency. Choose WebP if you need to preserve transparent areas, then check the exported result.
