Frequently Asked Questions
How do I compress or resize an image to 1MB?
Drop your image above. The tool binary-searches JPEG quality to land just under 1MB at the best possible quality, and only reduces the pixel dimensions if even low quality can't fit. Download the result instantly. Nothing is uploaded.
What dimensions fit in 1MB?
As a rule of thumb, a good-quality JPEG photo of about 2640×2640 pixels fits in 1MB. Simple images (documents, signatures, flat backgrounds) can be much larger; detailed photos with lots of texture need fewer pixels.
What is a 1MB image used for?
1MB limits are common for upload limits of 1MB on forms, CMSs, chat apps and marketplaces, and attaching several photos to one email. For example: a phone photo for a form that rejects files over 1MB.
