Frequently asked questions

How do I compress a photo without uploading it?

Drop your image into the tool above, pick a quality level, and the compressed version is generated instantly in your browser — nothing is ever sent to a server.

What's the difference between the quality presets?

High keeps the most detail with the largest file size, Small gives you the smallest file at lower quality, and Medium is a balance between the two. You can compare the before-and-after file size for each.

Does compressing change the image dimensions?

No. Compression only re-encodes the photo at a lower JPEG quality — the width and height stay exactly the same.

What file types can I compress?

You can upload JPEG, PNG, or WebP images. The compressed result is always saved as a JPEG, which compresses photos far more efficiently than PNG.
