How to compress an image to 80 KB, at or under the number

A 0 to 96 KB scale with the 80 KB cap marked: our 9.8 MB camera photo landed under it at 75.4 KB. The cap is 80,000 bytes, and the result is at or under it, never over.

Drop your image: the 80 KB cap is already armed, and the result comes back at or under 80,000 bytes, never over. EXIF and GPS come off every output, and files are wiped automatically. How the search trades quality against pixels, and the camera photo at every cap, are on the compress image to 50 KB page. Pixels the real problem? Resize image. The portal dictates the crop too? Crop image.

Every byte count is the size of the actual file our engine produced from the named source, the same bytes you would download, not an estimate. The reference photo is one of our own photographs, an iguana on a branch, and the camera photo is a real one too. Drop your own file into the tool above to rerun any of them.

The 80 KB jobs: the CAT photo and signature, and the direction of your rule

The CAT 2025 photo drawn as a 1200 × 1200 pixel square, the most its registration guide allows: a .jpg or .jpeg of not more than 80 KB at a minimum of 150 pixels per inch, the same cap as the 80 by 35 mm signature.

Eighty kilobytes is the CAT number. The CAT 2025 registration guide asks for a scanned passport-size photo within 1200×1200 pixels. The signature fits within 80 by 35 mm. Both go up as .jpg or .jpeg, each not more than 80 KB, at a minimum of 150 pixels per inch. Two files, one cap, one drop. Both rows come back at or under 80,000 bytes, and the readout prints each size. Before you use this page, read the direction of your rule. "Not more than 80 KB" is a ceiling, and this cap meets it. A rule written as a window that starts at 80 KB makes 80 the floor, and this cap lands you under it. Use the 100 KB page for that kind. Eighty is also the comfortable landing under a "less than 100 KB" rule. It leaves 20 KB to spare for a checker that counts 1,024-byte kilobytes. Our 9.8 MB camera photo came back at 75.4 KB with all 4964×2782 pixels kept. A 1200×1200 CAT photo has budget to spare. The 576.8 KB reference photo landed at 78.5 KB at its 1920×1280.

What does “80 KB photo size” mean?

The file’s weight on disk, not its pixels: a JPG at or under 80 KB. When a portal also rules on pixels, it states them separately, in px or cm, and the crop tool’s presets cover that rule.

Questions, answered

The cap is already armed above. One drop settles most of these.

Will the result be exactly 80 KB, or under it?

At or under, never over: that is the whole guarantee. The search maximises quality within the budget, so a result lands close beneath the cap when the image needs the room and further under when it does not. Under this page's 80 KB cap our 9.8 MB camera photo came back at 75.4 KB and our 576.8 KB reference photo at 78.5 KB. The readout under each result prints the exact bytes.

Does reducing the dimensions help an image compress to 80 KB?

Enormously: pixels are what bytes pay for. Under this 80 KB cap our 9.8 MB camera photo kept all 4964×2782 pixels and landed at 75.4 KB, so quality alone paid for the bytes. For a tight target, set Max resolution in Advanced settings yourself: it gives the quality search far more room to keep the face sharp. The engine shrinks a picture on its own only when the cap demands it.

What do "compress image in 80 KB", "compress image less than 80 KB", "80 KB converter" and "JPG 80 KB" mean?

The same thing portals ask for in their own words: a file that comes out as a JPG at or under 80 KB. This page is that converter. It preselects JPEG output, arms the 80 KB cap, and prints the exact bytes beside the result, so the words on the form and the file you upload finally agree.

What size does CAT want for the photo and signature?

The CAT 2025 registration guide sets four rules. The passport-size photo fits within 1200×1200 pixels and the signature within 80 by 35 mm. Both are .jpg or .jpeg files of not more than 80 KB each. The scan needs a minimum of 150 pixels per inch, and the photo must be not more than six months old. An 80 KB cap meets the byte rule for both files. Crop to the pixel size first and the rest follows.

How does 80 KB compare to 100 KB?

A quarter more bytes for the same pixels. Our 9.8 MB camera photo came out at 75.4 KB under the 80 KB cap and 97.3 KB under 100 KB. Both kept the full 4964×2782. Neither cap shrank the picture, so the extra bytes went into finer detail you find with the compare slider. Pick by the rule, not the look: 80 when the form says 80, 100 when it says 100.

Is 80 KB a maximum or a minimum on my form?

Read the wording. "Not more than 80 KB" or "up to 80 KB" is a ceiling. An 80 KB cap meets it, with the readout as proof. A window that starts at 80 KB has 80 as its floor. A file capped at 80 lands under it, so those forms need a larger cap. The difference decides whether the upload passes. When in doubt, the notice's own clause settles it, not a tool page.

Is 80 KB enough for an ID photo?

Yes. Our 576.8 KB reference photo kept all 1920×1280 pixels at 78.5 KB. Our 9.8 MB camera photo kept all 4964×2782 at 75.4 KB. An ID photo at the pixel size a form states, even CAT's 1200×1200 ceiling, is a smaller frame than the camera photo, so the budget goes further. The compare slider on the row shows what the cap cost; at 80 KB you have to look for it.

Will a prescription or document scan stay readable at 80 KB?

Yes, and the paper is why. We measured photographs, the harder case: our 9.8 MB camera photo kept all 4964×2782 pixels under this cap. A scanned page is mostly white, and JPEG spends almost nothing on white, so the bytes go to the printed text. Crop to the page edges, keep the scan upright, and set Max resolution to what the portal states. Zoom the result before you upload; the compare slider shows the two side by side.

Are there any disadvantages to compressing an image to 80 KB?

Two, and both show before you upload. Some detail goes: JPEG reaches 80 KB by lowering quality, and the compare slider on the row shows where. And the direction of the rule matters: "not more than 80 KB" is a ceiling this cap meets, while a window that starts at 80 KB makes it a floor a capped file lands under. The readout prints the exact bytes, so you see both before the portal does.
