Signature Generator

Signature Generator (brand name Paperloom) is a free online signature tool: type a name and within seconds you get 20 handwritten-style signature cards, and you can also place a signature on a PDF right in the browser. It does not imitate your handwriting and does not upload your files; underneath it is a parameterized rendering of 18 open-source handwriting fonts plus pseudo-random jitter.

Core capabilities

• 20 cards at once: one version for each of the 18 Google handwriting fonts, plus 2 more variants that reuse a font with a new random seed, so every style is visible at a glance
• Six-way fine tuning: weight 0.8–2.2, slant −12°18°, size 0.5–2, letter spacing −25, naturalness 0–1 and color, plus underline and flourish
• Three export formats: transparent PNG (2× the artboard size), vector SVG, and JPG on a white background, with one-click image copy
• Sign PDFs inside the browser: pdfjs reads the pages and pdf-lib writes the signature; unencrypted files up to 25 MB support multiple signatures across pages, and the file never leaves the browser
• Freehand drawing and photo cleanup: the stroke pad simulates pen pressure and shows reference guides; photos go through grayscale threshold binarization into vectors, up to 8 MB
• Zero barriers: no sign-up, no watermark, no usage caps, no credits, but also no API, no batch processing and no 300dpi output

Where it fits For visual "looks handwritten" uses such as résumés, quotations, internal forms, course slides, design mockups or email sign-offs, it is the low-effort choice, especially for individuals and teams that would rather not hand their files to a third party. If you need legal validity or Chinese signatures, you have to look for a compliant eSignature product instead.

Distinctive strengths Among peers it is unusually honest: free with no quota, no watermark, only two business endpoints on the whole site (login and config), SVG output that drops straight into Figma, and it openly states that it is not AI and carries no legal effect. The trade-off is that there is no real AI generation tier and no 300dpi or physical-size control.

Editorial take As a visual tool it is worth bookmarking: free, watermark-free and local processing are all backed by the code. But it should be said calmly that directory sites and submitted posts often call it "AI handwriting generation", while in fact it is a font engine plus linear congruential jitter, as the vendor itself writes. An image signature does not satisfy the four requirements of Article Thirteen of the Electronic Signature Law, so for major contracts switch to a compliant eSignature service; the domain was only registered on 2026-10-30 and there are zero genuine reviews.
