How it works
How to use Resize Signature to 20KB
Drop your signature photo — even a large phone picture of several MB works.
The limit is preset to 20 KB; choose the pixel size your form expects.
The tool crops, cleans and compresses, then shows the exact KB.
Download the JPG and upload it to your form.
Why use it
Why use our Resize Signature to 20KB tool
From MB to KB
Phone photos are often 3–5 MB. Cropping to the ink and resizing to a small pixel box brings them under 20 KB easily.
Best quality that fits
Quality is chosen by search, not a fixed setting, so the file is as sharp as possible while staying at or under 20 KB.
Honest result
If 20 KB cannot be reached at the pixel size you chose, you'll see the smallest possible size and what to change.
Works offline
Once the page loads, everything runs on your device — handy at a cyber café or on slow mobile data.
FAQ
Frequently asked questions
How do I reduce my signature size to 20 KB?
Upload it here, keep the ≤ 20 KB limit and pick a pixel size. The tool trims the paper, whitens the background and compresses the JPG until it fits.
My form says 'maximum 20 KB' — does a 9 KB file work?
Usually yes, if the form has no minimum. If it also states a minimum (for example 10 KB), switch the range to 10–20 KB instead.
Why does my signature look blurry at 20 KB?
Blur normally comes from a tiny pixel size or a blurry photo, not the KB limit. Use a sharper photo and the pixel size your form asks for.
Can I keep the original size instead of a preset?
Yes — choose 'Keep cropped size'. Without a fixed box, the tool may also scale the image down slightly if that's needed to get under 20 KB.
