How to resize a signature to 20 KB

Upload a JPG, PNG or WebP signature. The 20 KB limit is already selected, so you can keep the original dimensions or enter the pixels requested by your form. Choose Resize Signature and download only when the final file passes the 20 KB check.

Why online forms require small signature files

Application forms and document portals often use small upload limits to keep submissions fast and consistent. A 20 KB signature is easier to store and transfer, while still being readable when the source image and format suit the requirement.

Dimensions and format affect a 20 KB signature

Smaller dimensions usually produce a smaller file. JPG and WebP can adjust compression to meet a KB limit, while PNG keeps transparency but may not fit every strict limit. You can choose the format, preserve transparency where supported, or use a white background when converting a transparent signature to JPG.

The result is checked against the selected dimensions, format and any file-size limit before the download button appears. For another requirement, use the full Signature Resizer or the Image Requirements Checker.

Private browser-based signature processing

Your signature stays on your device. KEVRIQO performs the resize, crop, compression, format conversion and final validation in your browser, without uploading the source image to our servers.

Frequently asked questions

How can I make a signature under 20 KB?

Upload it here and keep the 20 KB preset selected. If the source is too large, try smaller dimensions or a JPG or WebP output format.

Can I set my own signature dimensions?

Yes. The 20 KB preset does not lock dimensions. Enter the width and height your application requires, then use Crop to fit only when you need an exact shape.

Is the result really limited to 20 KB?

Yes. KEVRIQO checks the generated file against the 20 KB limit before showing Ready for upload.

Can a transparent signature be 20 KB?

PNG and WebP can retain transparency. If a transparent PNG cannot meet 20 KB, try WebP or convert to JPG, which uses a white background.
