Free artist signature identification app
An artist signature can be important, but it is only one clue. A free signature identification app helps read the mark, compare it to the object, and decide whether more appraisal work is needed.
Found artwork and want to know if it matters?
Upload photos. We identify the object, check real sales, and show the right appraisal path.
Use the free screenerArt appraisalsStart an appraisalOne clear answer
Start with clear photos of the signature, then check medium, subject, paper or canvas, labels, edition, frame, condition, and whether the style supports the name.
Auction records are market evidence, not a final appraisal. Condition, authenticity, provenance, size, medium, edition, subject, and demand can materially change value.
Photo checklist
- Photograph the whole artwork, signature, initials, date, edition, labels, back, stretcher, frame, and any inscriptions.
- Use sharp, glare-free close-ups from straight on and at a slight angle.
- Do not trace, darken, clean, or repaint a signature before review.
What changes the answer
- A signature matters only when medium, style, date, provenance, and condition support it.
- Pencil-signed prints, signed posters, signed paintings, and estate stamps have different standards.
- Unknown or illegible signatures can still be appraised by quality, medium, subject, and comparables.
Auction evidence from Appraisily's database
Recent signed art records show why a signature can help but does not guarantee high value. These are market examples, not promises for your artwork.

| Pencil-signed lithograph | Albion Antique Auction Centre | Apr. 30, 2026 | Leonor Fini coloured lithograph, signed and editioned lower in pencil | AUD 40 | Signature and edition are useful, but condition and market demand remain decisive. |

Condition and authenticity cautions
Do not assume a famous name is authentic from a signature alone. For high-value art, authentication and provenance may be more important than visual signature matching.
Use a professional appraisal or authentication path when the artwork may be significant, has legal use, or depends on artist attribution.
When the free screener is enough
Use the free screener when you need first-pass identification, condition review, and market direction before selling, donating, reframing, cleaning, or ordering a formal appraisal.
When to get a professional appraisal
Use a professional appraisal for insurance, estate, donation, legal, or higher-value sale decisions. See the professional sample report.

FAQ
Can an app identify every artist signature?
No. It can help triage clear signatures and point to next steps, but obscure marks may need research or authentication.
Is a signature enough to prove authenticity?
No. Medium, style, provenance, labels, and expert authentication may be needed.
What if the signature is hard to read?
Upload the full artwork plus angled close-ups, back labels, dates, and inscriptions.
Need a clearer art answer?
Upload photos. Appraisily identifies the artwork, checks real sales where available, and shows whether a free screen or professional report makes sense.
