Load one or many PDFs, drag a transparent PNG signature onto any page, resize it, and
save each file with a _signed suffix. Nothing is ever uploaded.
Everything runs locally in your browser. Your PDFs and signatures never leave your computer — no server, no upload.
Drop PDFs to open them and PNGs to place them. Move and resize each image right on the page.
Save your signatures once. They're remembered across sessions and remember their size, so stamping a batch is fast.
Open many PDFs at once and export them all together — each saved as
name_signed.pdf.
