Compress an image to 6 MB.

Drop your photos and download each one as a JPG under 6 MB. The quality is lowered first and the pixel dimensions only when that is not enough; the photo is never cropped. It runs in your browser; nothing is uploaded.

6 MB in numbers.

Counted as the compressor counts: 1 KB is 1,000 bytes and 1 MB is 1,000,000 bytes. Bits per pixel divides the limit in bits by the pixels of a 12-megapixel phone photo (4,032 × 3,024 px) kept at full size; the uncompressed size counts 3 bytes per pixel.

Questions

6 MB, answered.

Which platforms ask for 6 MB?

YouTube and eMAG. The table on this page gives each rule in full and links to the platform's guide.

How many bytes is 6 MB?

6,000,000 bytes: the compressor counts 1 MB as 1,000,000 bytes, the stricter of the two common readings. Counted in units of 1,024, 6 MB would be 6,291,456 bytes, so a file under 6,000,000 bytes is under the limit on either count.

How many bits per pixel does 6 MB leave for a 12-megapixel photo?

3.94, if the photo keeps all 12,192,768 pixels (4,032 × 3,024): 48,000,000 bits divided by 12,192,768. Uncompressed, at 3 bytes per pixel, the photo is 36,578,304 bytes, 6.1 times the limit. The compressor lowers the JPG quality first and reduces the pixel dimensions only when that is not enough.
