masstree.inCompress Image to 20 KB
For signature and small photo uploads: every image is squeezed to fit under 20 KB, keeping as much detail as possible.
Runs in your browser — nothing is uploaded or stored on a server.
Settings
Metadata (EXIF, GPS) is always removed. Leave width and height empty to keep the original size. Each file row has crop and favicon-pack buttons; a rename pattern uses {n} for a number and {name} for the original name.

Drag inside the box to move it, drag the corner to resize, or draw a new box.
Where 20 KB comes up
SSC, railway, bank and state exam forms usually want a signature of 10–20 KB and a photo of 20–50 KB, often as JPG only.
How it works
The tool lowers JPEG quality first and only shrinks the image if quality alone isn't enough, so text in a signature stays crisp.
For signatures
Sign in black ink on white paper, photograph it in daylight, then crop tightly with the crop button before compressing — the “Signature” preset also sets a 280 × 100 px size.
Questions
Will it stay sharp?
Signatures and passport photos stay clear at 20 KB. Large detailed photos lose some detail.
Which format do I get?
JPG, which every form accepts.
Is my photo uploaded?
No, it is processed in your browser.
