Frequently asked questions
How do I make a photo smaller than 1 MB?
Add it and press Compress; the 1 MB target is preset. Phone photos of 3–6 MB usually fit under 1 MB with no visible difference.
Why does a site say my file is too large?
Many sites limit uploads to 1 MB or less to save storage and bandwidth. Compressing the photo to the limit fixes the error without changing what it shows.
Can I keep PNG format?
Yes, but PNG photos compress far less than JPG or WebP. For photos, switching to JPG makes the 1 MB target easy to reach.
Are my files uploaded to a server?
No. Compress Image to 1 MB runs entirely in your browser, so your files stay on your device. Nothing is uploaded, stored or seen by anyone else.
Is Compress Image to 1 MB free?
Yes. It is completely free, with no sign-up and no watermarks.
