The message, and where it comes from
Image is overly compressed. Please use a compression ratio that is less than 20:1
This is the United States Department of State photo tool — the one used for the Diversity Visa (green card) lottery and for visa and passport photo uploads. It is one of the most confusing rejections in the whole process, because it does not tell you what to change.
⚠️ It is not saying your file is too big. It is saying your file is too small for its own dimensions.
What a compression ratio is
It compares your file against the same image with no compression at all.
An uncompressed 24-bit colour image takes width × height × 3 bytes. So:
- A 600 × 600 photo is about 1,055 KB uncompressed
- A 1200 × 1200 photo is about 4,219 KB uncompressed
Divide that by your actual file size and you have the ratio. A 600 × 600 photo saved at 40 KB is compressed about 26:1 — past the limit, and rejected.
The floor moves with your photo's size
This is the part that catches people, and almost nothing explains it.
| Your photo | Must be at least | Ceiling | Workable range |
|---|---|---|---|
| 600 × 600 | 53 KB | 240 KB | 187 KB wide |
| 800 × 800 | 94 KB | 240 KB | 146 KB wide |
| 1000 × 1000 | 147 KB | 240 KB | 94 KB wide |
| 1200 × 1200 | 211 KB | 240 KB | 29 KB wide |
🔑 The largest photo the portal allows is also the hardest one to get accepted. At 1200 × 1200 — the maximum permitted size — everything has to land in a window about 29 KB wide. At 600 × 600 you have a 187 KB window to aim at.
That is why uploading the biggest, best photo you have so often fails.
The fix nobody mentions: make it smaller
Every other guide says the same thing — re-save at higher quality. That is correct, and it is the harder half.
Shrinking the photo in pixels lowers the floor at the same time. Going from 1200 × 1200 to 600 × 600 drops the requirement from about 211 KB to about 53 KB. Suddenly almost any reasonable save will pass, and 600 × 600 is fully accepted — it is the portal's own stated minimum, not a compromise.
So, in order:
- Start from the original if you still have it, rather than a copy that has been through a messaging app.
- If you are near 1200 × 1200, go down to 600 × 600. You lose nothing the portal wants.
- Then save at a higher quality setting if it is still under the floor.
⛔ Do not enlarge a file that is already heavily compressed in the hope of passing. The detail was discarded when it was first saved, and adding bytes does not bring it back — it only produces a larger version of the same damaged picture.
Where this number comes from, honestly
🔑 The quotation above is the source. The rule is stated by the tool itself, in its own rejection message, which is as direct as a specification gets.
⚠️ We have not been able to read the State Department's published requirements page directly — travel.state.gov and dvprogram.state.gov both refuse automated requests — so this page quotes the tool rather than citing a page we did not open. The 240 KB ceiling in the table above is the figure stated consistently across the industry and is not something we could verify at source; treat it as the working number and check your own upload screen.
That distinction is deliberate. Everything else we publish about portal photo rules links to the authority that set it, and where we cannot, we say so rather than borrowing someone else's confidence.
Check your photo before you upload it again
Check my photo now measures this ratio directly. Drop in your file, choose the United States visa, and it will tell you the compression ratio, the floor at your pixel size, and how far off you are — in your browser, with nothing uploaded.
