Target: 20 KB

Compress an image to 20 KB

A 20 KB target is preset below, with the same engine as the main compressor. You will see the true resulting size — and a clear warning if 20 KB is not achievable without visible damage.

Short answer: drop the photo, keep the target at 20 KB and compress. The tool searches JPEG quality first and only then reduces dimensions, so you get the largest image that fits under the limit. The badge tells you whether 20 KB was actually reached.

Getting a useful 20 KB image

Add the image. Start with the original, not a screenshot of it.
Leave the target at 20 KB. If the image is a detailed photo, also set a maximum dimension of 800–1200 px.
Keep the output format the same as the input unless you need a specific type.
Compress, then check the badge: Target reached or Closest possible.
Open the downloaded file before submitting it to a portal.

When 20 KB is realistic

Realistic for a headshot at 200–400 px, a logo, a signature scan, or a plain background.
Hard for a full-resolution photo with foliage, text or noise. Downscaling matters more than the quality slider at this size.
Impossible for PNG screenshots of text without blur: PNG is lossless, so the engine can only reduce dimensions.

The tool never labels an over-target file as done. Transparency, EXIF removal and format handling match the main compressor.

Questions

Why does a portal reject a file that is exactly 20 KB?

Many portals count 1 KB as 1,000 bytes while the file itself is measured in 1,024-byte kilobytes, so “20 KB” on their side is slightly smaller. Compress to 19 KB instead, or download a version a few hundred bytes smaller.

My signature is only 5 KB and the form wants 10 to 20 KB. How do I make it bigger?

Compression only removes bytes. Open the resize tool, increase the pixel size (for example 280 × 120 px for a signature), then compress that larger image toward 20 KB. The result grows because there is more detail to encode.

Which exam and application forms ask for 20 KB images?

20 KB is a common ceiling for photographs and signature uploads on Indian recruitment and admission portals, typically paired with a fixed pixel size such as 200 × 230 px for a photo or 140 × 60 px for a signature. Rules change per notification, so always re-read the one you are applying under.

Will the result always be under 20 KB?

No, and no honest tool can guarantee that for every image. The compressor lowers quality and, if needed, dimensions within a bounded number of steps. If it still cannot reach 20 KB, it shows “Closest possible” with the actual size.

Why is my photo still far above 20 KB?

Fine detail, noise and large dimensions cost bytes. A 4000 px photo often needs to be scaled down first. Set a maximum dimension of 800–1200 px for a 20 KB target, or start from a smaller image.

Is 20 KB enough for an ID photo?

That depends entirely on the form you are submitting to. Many portals ask for 10–100 KB but each has its own pixel and format rules. Check the requirement, then set the matching dimensions and size here.

Does it upload my photo?

No. The image never leaves your device: it is decoded and re-encoded by your browser, and the download is created from memory.
