Compress JPEG Between 10KB and 20KB
A 10–20 KB window is narrow, so the encoder has to hit a small target from both sides. Quality is searched against the 20 KB ceiling, and the result stays inside the range using proportional resizing when required.

To meet the file size limit, pixel dimensions may be reduced proportionally if needed.

Hitting a 10–20 KB JPEG Window
A tight interval where the floor and the ceiling both decide whether the file is accepted.
Two Limits, One Window
The File Size Range fields set a 10 KB minimum and a 20 KB maximum, so the exported JPEG has to land between them rather than merely stay under a cap.
Quality Search Against 20 KB
The encoder searches JPEG quality levels to stay at or below 20 KB and keeps the largest result it can produce inside that ceiling.
Padding When the File Is Too Small
If the encoded JPEG falls under 10 KB, valid JPEG metadata is appended so the file reaches the minimum without altering the pixels or the dimensions.
Dimensions Stay as Selected
This range mode reduces width and height proportionally if quality compression cannot meet 20 KB.
Very Small Output, Very Low Detail
A 10–20 KB JPEG has room for a small thumbnail or a simple subject. Fine texture and small text soften noticeably, and blocking becomes visible.
Runs in Your Browser
Encoding and the range search happen locally, so you can retry different dimensions without uploading the source image to a processing server.
Compress a JPEG Into 10–20 KB in 3 Steps
Upload an image, keep the range and check both the lower and the upper limit.
Upload the Image
Choose a JPG, PNG or WebP up to 20 MB. The result is always encoded as a JPEG file.
Keep the 10–20 KB Range
Leave 10 as the minimum and 20 as the maximum, or edit either field when another requirement uses a different window.
Compress and Verify
Confirm that the download is at least 10 KB and at most 20 KB. Dimensions are reduced proportionally when needed to meet the ceiling.

10–20 KB JPEG Compression FAQ
A narrow interval, the lower limit and what happens at the ceiling.
Only small or simple images. Detailed photos usually need much smaller pixel dimensions before they fit under the 20 KB ceiling.
It appends valid JPEG comment metadata to reach 10 KB. That step changes the byte count but leaves the pixels and the dimensions as they are.
The tool now shrinks dimensions proportionally when quality compression alone cannot meet 20 KB.
No. The encoder keeps the best quality it can produce at or below the ceiling, so many results land somewhere inside the window rather than on the boundary.
For a small avatar at modest dimensions it can be, although faces lose fine detail and plain backgrounds flatten into blocks.
Only with standards-compliant JPEG metadata. The page does not insert visible content or extra image data to inflate the file.
Yes. Supported inputs are decoded in the browser and re-encoded as JPEG, so transparency is filled instead of being preserved.
No. The compression search runs locally in your browser, and the source file stays on your device.
Yes, our image resizing tool is completely free to use. No registration required, no watermarks, and no hidden fees. Simply upload your image and resize it to your desired dimensions.
Absolutely! All image processing is done locally in your browser. Your images are never uploaded to our servers, ensuring complete privacy and security of your files.
