About
With Siglume, you can capture a handwritten signature from a photo, clean it up using advanced tools, save it on your device, and reuse it whenever you need to sign a PDF. Everything is processed locally, with no account required and without uploading your documents or signatures to external servers.
CREATE YOUR SIGNATURE
Take a photo of your signature or import an image from your photo library. Siglume guides you through a simple and precise process:
• crop and straighten the image;
• rotate it freely;
• automatically remove the background;
• adjust sensitivity, contrast, and speckle reduction;
• choose the ink color;
• create a signature with a transparent background.
The real-time preview lets you check the result as you make each adjustment.
REFINE EVERY DETAIL
Use the built-in editor to perfect your signature before saving it:
• erase unwanted areas;
• restore or correct strokes with the brush;
• rotate the signature.
Your signature is saved in high quality and automatically cropped around the handwritten strokes.
YOUR SIGNATURE LIBRARY
Store multiple signatures directly on your device and quickly access them from your library.
You can:
• edit an existing signature;
• duplicate it to create different versions;
• delete it when you no longer need it;
• reuse it across different documents.
SIGN YOUR PDF DOCUMENTS
Open a PDF from the Files app, import it from another application, or capture a document directly with the camera.
Select a signature from your library and place it on the document. You can add multiple signatures to the same page and, for each one:
• move it;
• resize it;
• rotate it;
• delete or reposition it.
Browse through the pages, zoom in for greater precision, and review the document before exporting it.
SIMPLE EXPORTING
When you are finished, Siglume creates a new copy of the PDF with the signatures applied. The document is flattened to keep signatures, annotations, and completed form fields visible, and can then be saved or shared using the system share menu.
CHOOSE THE FILE SIZE
Use a simple slider to set the maximum size of the exported PDF. Siglume automatically optimizes the document to help you meet the file size limits required by email services, online portals, and sharing platforms.
PRIVACY FIRST
Siglume works entirely locally:
• no account required;
• no mandatory synchronization;
• no signatures or documents uploaded to external servers;
• your content stays on your device.
