Resize first if the portal asks for exact pixels. Compress after resizing if it also checks the KB limit.
Requirements
Signature upload checklist
Most portals care about both dimensions and file size. Always confirm the exact requirement on the live application page.
| Need | Typical target |
|---|---|
| Dimensions | 300x80 px for many job/exam forms |
| File size | 20KB or lower when the portal rejects large files |
| Readability | Dark pen stroke on clean white background |
Workflow
Prepare a signature in four steps
Scan cleanly
Use a white background and keep the signature stroke visible.
Resize
Pick the PPSC or FPSC preset when the portal asks for exact pixels.
Compress
Use the 20KB compressor if the resized file is still too large.
Upload
Download the final JPG and upload it to the application portal.
Guide
Common signature upload mistakes
Stretching the signature
Use fit mode when available. It keeps the stroke natural instead of squeezing it into a rectangle.
Cropping too tightly
Leave a little white space around the pen stroke so the signature stays readable after resize/compression.
Using PNG for tiny limits
JPG usually reaches 20KB more easily than PNG for scanned signature images.
FAQ
Signature tool questions
Should I resize or compress my signature first?
Resize first when the portal asks for exact pixels. Compress after resizing when it also asks for a small KB size.
Does Kodotools upload my signature?
No. Your signature is processed locally in your browser and stays on your device.
Which format is best for a 20KB signature?
JPG is usually best for very small signature files because it compresses more easily than PNG.
