The handwritten declaration text
The guidelines give this text. Write it in English, in your own normal handwriting (not capital letters), with a black pen on white paper, filling in your details:
“I, ______ (Name of the candidate), Date of Birth ______, hereby declare that all the information submitted by me in the application form is correct, true and valid. I will present the supporting documents as and when required. The signature, photograph and left thumb impression is of mine.”
Tips that avoid rejections
Use plain white paper with no lines, and photograph it from straight above in daylight, without your phone's shadow.
Fill most of the photo with the signature, print or text — the tools crop the rest and clean the paper to white.
Keep JPG as the format. Check the size shown under each result before uploading.
If you don't have a left thumb, the guidelines allow the right thumb.
Bank exam documents — FAQ
What are the IBPS photo and signature sizes?
Per the IBPS/SBI upload guidelines: photo 200×230 pixels, 20–50KB; signature 140×60 pixels, 10–20KB; left thumb impression 240×240 pixels, 20–50KB; handwritten declaration 800×400 pixels, 50–100KB — all JPG. Always check the notice for your exam, as numbers can change.
My signature is under 10KB. Will it be rejected?
It can be, if the form checks the minimum. SlimIO makes the clearest version under 20KB and, if a small signature still comes out below 10KB, adds harmless padding data so the file meets the minimum — the image itself doesn't change.
How do I make the left thumb impression image?
Press your left thumb on a black or blue ink pad and onto plain white paper, photograph it from above in good light, then open the thumb impression tool. It cleans the paper to white, crops to the print and saves a 240×240 JPG between 20KB and 50KB.
Can I write the declaration in capital letters?
No. The guidelines say declarations (and signatures) in CAPITAL LETTERS are not accepted. Write in normal handwriting, in English, with black ink.
Are my documents uploaded to your server?
No. Photos, signatures and declarations are processed entirely in your browser and never leave your device.
