Resize a scanned or photographed signature for online forms: trim the empty paper, clean the background to white, darken the ink and save a JPG at the exact pixel size and KB range the form asks for, such as 140 × 60 px and 10–20 KB.
Works in your browser. What you paste or upload is processed on your device.
Sign with a black or blue pen on plain white paper and take a sharp photo or scan in good light.
Choose the photo. The tool trims the paper and cleans the background straight away.
Choose the IBPS or SSC preset, or enter the width, height and KB range from your exam notice.
Adjust background clean-up, ink darkness and colour until the strokes are crisp and the paper is white.
Press Create signature JPG and download the file. Its pixel size and KB are shown with the result.
Online application forms for bank, government and university exams ask for a signature image with a fixed pixel size and a file size window, for example 140 × 60 pixels and 10–20 KB. A phone photo of your signature is usually far too big, grey and full of empty paper. This signature resizer turns it into a clean JPG that meets the numbers: it trims the empty margins around the ink, evens out shadows and turns the paper pure white, darkens the strokes, then fits the signature into the target size with a small white border and saves it inside the KB range.
Presets cover the values printed in recent IBPS notices (140 × 60 px, 10–20 KB, used for PO, Clerk and RRB forms) and SSC notices (6.0 × 2.0 cm, 10–20 KB). For any other form, enter the width, height and KB range from its notice. You see the cleaned result and its expected file size before you spend a run.
Honest limits: the clean-up works best on dark ink on light paper. Very faint pencil, lined or coloured paper, and photos with strong glare may need a better photo. If a form wants a minimum size larger than the clean image reaches at top quality, the tool pads the file with an empty comment block so it reaches the minimum without changing how the signature looks. Exam rules change between cycles, so check your notice before uploading.
Signature uploads are one of the most common reasons an application gets stuck: the file is too big, too small, the wrong shape or too grey for the portal to accept. Getting the exact size takes a few seconds here, on your own device, without installing an app or sending your signature to a website's server.

Recent IBPS notices (PO, Clerk, RRB) ask for a 140 × 60 pixel JPG between 10 and 20 KB. Recent SSC notices ask for a JPG between 10 and 20 KB at about 6.0 × 2.0 cm. Both are presets here, but each cycle's notice is the final word, so check the one you are applying under.
Choose a preset or enter a maximum of 20 KB. The tool saves the JPG at the highest quality that stays under the limit. A clean signature on white compresses very well, so most signatures fit easily without visible loss.
Enter the minimum (for example 10 KB). The tool first raises JPG quality; if the file is still too small, it adds an empty comment block inside the JPG so it reaches the minimum. The picture itself doesn't change, and portals read the file normally.
Keep Clean background on. The tool estimates the paper's brightness across the whole photo, so shadows and uneven light become white, and only the ink stays dark. Raise the clean-up level if grey patches remain; lower it if thin strokes start to disappear.
Yes, upload the screenshot or exported image. Some exams require a signature made with a pen on paper, so check the notice. Note that many forms reject signatures in capital letters or signatures that don't match the one you sign at the exam.
No. The trimming, cleaning, resizing and compression all run in your browser. Our server only counts how many times the tool was used so the daily free run can be applied.
Yes. On iPhone or Android, take a photo of your signature or pick one from the gallery, choose the preset and download the JPG straight to your phone for the upload.
