Frequently Asked Questions
Should I choose side-by-side or stacked layout?
It depends on the portal's requirements. Side-by-side layout places the thumb impression on the left and signature on the right - ideal for most SSC and IBPS forms. Stacked layout puts the thumb on top and signature below, which is better when the portal expects a taller combined image. Check your exam notification for the recommended layout.
What is the maximum file size allowed for the combined image?
Most government exam portals accept combined images between 20 KB and 50 KB. Our tool exports a high-quality JPEG that you can further compress using our Image Compressor tool if needed. SSC typically allows up to 50 KB for the combined image, while IBPS and SBI may allow up to 100 KB.
Which thumb impression should I use - left or right?
Almost all Indian government and banking exams (SSC, IBPS, SBI, RRB, UPSC) require the left thumb impression. Right thumb is used only if the left thumb is missing or injured, and you must provide a declaration for the same. Always use blue or black ink on a white background.
Is it safe to upload my thumb impression and signature here?
Yes, 100% safe. This tool processes everything locally in your web browser using the HTML5 Canvas API. Your thumb impression and signature are never uploaded to any server. You can even disconnect from the internet while using this tool - it will continue to work perfectly.
