Turn a phone photo of your handwritten signature into a clean white-background JPG. Auto crop, contrast boost, and exam size presets — no upload.
Quick start
You signed white paper, photographed it with your phone, and the upload shows gray shadows and creases around the ink.
Step 1
Upload the photo
JPG or PNG from your camera roll — no scanner required.
Step 2
Use auto threshold
Otsu detection separates paper from ink; switch to manual if edges look eaten.
Step 3
Enable auto crop
Trims margins so the signature fills the export box cleanly.
Step 4
Pick exam size preset
SSC or IBPS dimensions with optional KB compression.
Step 5
Download or merge
Use the JPG directly, or open the photo+signature merger for a combined upload.
Expected results: White-background signature with dark blue-black ink, cropped tight, sized for your exam preset.

Photograph your signature on paper and this tool removes the gray paper background, darkens the ink, and crops to the stroke bounds. Otsu auto-threshold handles uneven lighting; manual controls are available when needed. Export at SSC (200×75) or IBPS/SBI (140×60) dimensions with optional KB compression for government job portals. Everything runs locally in your browser.
No. Scanned Signature Cleanup works right away client-side with no registration.
Yes. Standard flows process locally on your machine, so files are not uploaded as part of normal usage.
Practically speaking, anyone handling practical image workflows who needs fast on-device execution without heavyweight local installs. That makes the result easier to verify before publishing.
In day-to-day use, yes, though larger files and advanced operations generally perform better on desktop hardware with more memory. This is usually the most reliable approach for repeatable results.
In most workflows, no account is required for core workflows. You can start immediately and process directly right here.
