Frequently Asked Questions
How do I compress an image to 1MB online?
Upload the image, set the quality to about 75%, then click compress. The tool adjusts automatically until the result is under 1MB.
What file sizes can be compressed to 1MB?
Almost any photo. Files up to 100MB are supported; very high-resolution photos are compressed more so they fit under 1MB.
Does the quality stay good at 1MB?
Yes. For photos, 1MB is plenty sharp on phone and laptop screens. Only lower the target if your upload form demands a smaller size.
