Compress an image to 10 MB.
Drop your photos and download each one as a JPG under 10 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.
Under 10 MB per image, saved as JPG

10 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.
- Bytes
- 10,000,000
- Bits
- 80,000,000
- Pixels in a 12-megapixel phone photo
- 4,032 × 3,024 = 12,192,768
- Bits per pixel at full size
- 80,000,000 ÷ 12,192,768 = 6.56
- Uncompressed, 3 bytes per pixel
- 36,578,304 bytes, 3.66 times the limit

Which platforms ask for 10 MB?
bol, Kaufland, Vestiaire Collective, Coupang, YouTube, LinkedIn ads, Newegg, Big Cartel, Walmart Connect, Reddit Ads, Mailchimp, Klaviyo, noon, OnBuy, Tradera, and Jimdo. The table on this page gives each rule in full and links to the platform's guide.
How many bytes is 10 MB?
10,000,000 bytes: the compressor counts 1 MB as 1,000,000 bytes, the stricter of the two common readings. Counted in units of 1,024, 10 MB would be 10,485,760 bytes, so a file under 10,000,000 bytes is under the limit on either count.
How many bits per pixel does 10 MB leave for a 12-megapixel photo?
6.56, if the photo keeps all 12,192,768 pixels (4,032 × 3,024): 80,000,000 bits divided by 12,192,768. Uncompressed, at 3 bytes per pixel, the photo is 36,578,304 bytes, 3.66 times the limit. The compressor lowers the JPG quality first and reduces the pixel dimensions only when that is not enough.
