About Compress image

What does Compress image do?
Reduce image file size with a quality slider and a live before/after size.
Who is it for?
Creators and sellers preparing product photos, job applicants sizing a profile picture, anyone posting to a platform with strict image requirements, and people who want to strip location data before sharing a photo.
Is it free?
Yes. Compress image is free with no account, no watermark on your output, no daily cap and no trial period. Because it runs on your own device it costs us nothing to run, which is why there is no catch.
Is it safe to use with confidential files?
Yes, and not because we promise to behave. Compress image never sends your file anywhere — the work happens in your browser. There is no upload, so there is no copy of your document in our systems at any point.
What file formats are supported?
Input: JPG, JPEG, PNG, WEBP. Output: JPG, WEBP, PNG.
Which quality setting should I use?
80% is the usual sweet spot — a large size saving that most people cannot see. Below about 60% you start to notice blocking in flat areas and around text.
Should I convert to WebP as well?
For the web, yes. WebP is typically 25–35% smaller than JPEG at the same visible quality and is supported by every current browser.

How to use it

  1. 1

    Add your file

    Drag it onto the box above, or use Browse files. On a phone you can also take a photo or pick from your camera roll.

  2. 2

    Check the settings

    Sensible defaults are already chosen. Most people never need to change them.

  3. 3

    Run it

    The progress bar shows real progress, not a decorative animation. Everything happens on your device.

  4. 4

    Preview the result

    Look at the output before you download. If it is not right, adjust a setting and run it again — nothing has been saved anywhere.

  5. 5

    Download

    Save the file. Closing this tab discards it from memory, so download anything you want to keep.
