Your RRB signature should be 140 × 60 px, with a file size of up to 70 KB, saved as JPG/JPEG.
How do I resize a signature for RRB?
Upload your signature on this page, and it's automatically cropped and compressed to the official RRB signature requirement (140 × 60 px) — no separate crop or resize step needed.
How do I get my RRB signature within up to 70 KB?
This tool checks the actual downloaded file size against the up to 70 KB requirement and adjusts compression automatically, so the file you download already falls inside that range.
Can I use this as a RRB signature compressor too, not just a resizer?
Yes — resizing to the correct dimensions and compressing to the required file size happen together in one step here, so you don't need a separate RRB compressor tool.
Are my photos uploaded to a server?
No — resizing and compression run entirely in your browser. The one exception is background removal, which uses an on-device AI model that's downloaded once and then also runs locally; your image itself is never sent anywhere.
