India Post GDS Signature Resizer
Resize your signature for the India Post GDS application and bring the file size below the 20 KB limit. Crop unnecessary space, adjust the image, and save a clear JPG or JPEG file ready for online registration.
India Post GDS Signature Size Requirements

Before Uploading Your GDS Signature
A few simple checks can make the final file easier to upload:
- Use a clear signature with good contrast.
- Keep the background clean and free from unnecessary marks.
- Crop blank space around the signature before reducing the file size.
- Save the final image as JPG or JPEG.
- Make sure the file is 20 KB or smaller.
- Open the downloaded image once and check that the signature is still readable.
GDS Signature Upload Not Working?
If the India Post portal does not accept your signature, check the file rather than recreating the signature immediately.
| Problem | What to check |
|---|---|
| File is above 20 KB | Compress the image until it is within the 20 KB limit. |
| Wrong file type | Save the final image as JPG or JPEG. |
| Signature looks blurry | Start with a clearer source image and avoid excessive compression. |
| Too much blank space | Crop the image around the actual signature before resizing. |
| Signature is partly cut off | Re-crop the image and keep the complete signature visible. |
| File still won't upload | Compare the final image with the current GDS portal instructions. |
If the file meets the stated requirements but the upload still fails, our Signature Upload Failed Fix Guide can help identify other common image problems.
Why Does a GDS Signature Need to Be Under 20 KB?
A smaller file is easier for the application portal to accept, but reducing the size too aggressively can make the signature difficult to read. The goal is not simply to make the image as small as possible—it is to keep the file within the 20 KB limit while retaining a clear signature.
That is why cropping unnecessary blank space before compression can be useful. It removes pixels that do not contribute to the signature and gives the image compressor less unnecessary content to process.
