About the Image Compressor
The Image Compressor shrinks JPEG, PNG, and WebP files right in your browser so your pages load faster without sacrificing visible quality.

Every image is processed locally on your device and is never uploaded to a server, so your files stay completely private.

- Adjust the quality slider and pick an output format (keep original, JPEG, WebP, or PNG) to balance file size against image quality.
- Review the original size, compressed size, and percent saved, then click Download to save the optimized image.

Frequently asked questions
Are my images uploaded to a server?
No. All compression happens locally in your browser using the Canvas API. Your images are never uploaded, sent, or stored anywhere, so they remain completely private.
Which output format should I choose?
WebP usually gives the smallest file size with excellent quality and is well supported by modern browsers, making it ideal for the web. JPEG is a safe, universal choice for photos, while PNG is best when you need transparency or sharp graphics. Choose 'keep original' if you want to stay in the same format.
Does compression reduce image quality?
Compression can reduce quality, especially at lower slider settings, because it re-encodes the image to remove data. At higher quality levels the difference is usually hard to notice, so you can adjust the slider and compare the result until you find the right balance for your needs.
Is there a file size limit?
There's no hard file size limit imposed by the tool, but because everything runs in your browser, very large images can use significant memory and take longer to process on lower-powered devices. For best results, work with reasonably sized photos a few megabytes or smaller.
Will it strip EXIF and other metadata?
Yes. Because the image is re-encoded through the Canvas API, most metadata such as EXIF camera data, GPS location, and color profiles is dropped from the compressed output. This is helpful for privacy and trimming extra bytes, but keep an original copy if you need to retain that information.
