Signe PDF — Gratuit, Privé, Cryptographique
Ba signature visible NA ba signature numérique cryptographique ya solo (PKCS#7) — nionso mibale ya ofele, nionso mibale ya mboka, nionso mibale endimami na mibeko
Drop a PDF and we open it in the editor with the Certify modal pre-selected. Draw your signature with mouse / trackpad / finger, type your name, or upload a signature image. Add reason / location / date fields. Place the visible signature anywhere on the page. We cryptographically sign the output using an in-browser-generated RSA-2048 self-signed certificate (or your own .p12 if you have one). Your PDF, your signature, and your private key never leave your device. No signup, no watermark, no per-signature charge. The only free PDF signer that does real cryptography.

Ndenge nini okoki ko signer PDF ofele
1. Bwaka PDF na yo
Benda PDF na zone ya kokita likolo, to finá mpo na kotala. Mobongisi efungwamaka automatiquement na modal Certify oyo eponami liboso — navigation te na ba menu, koluka esaleli ya signature te.
2. Salá dessin, koma to tyá signature na yo na Internet
Modal Certify epesaka banzela misato mpo na signature oyo emonanaka: benda na souris, trackpad, to mosapi na yo na écran tactile; komá nkombo na yo na makomi ya solosolo oyo otye sinyatili; to ko uploader PNG / JPG ya signature na yo oyo ezali. Nyonso misato ebimisaka mbano moko oyo emonanaka —pona oyo ezali ya bomoto mingi mpo na yo.
3. Bakisa ntina, esika, mpe dati
Na spec PDF 2.0, ba signature cryptographique ememaka raison optionnelle (e.g. "Nazali mokomi"), esika (e.g. "Berlin, Allemagne"), mpe ba champs ya date. Ba vérifiers ba monaka oyo pembeni ya état ya crypto. Totondisaka date yango na ndenge ya automatique; tondisa oyo etikali soki contexte esengi yango.
4. Tyá sinyatili mpe sinyatili
Finá esika nyonso na lokasa mpo na kobwaka rectangle ya signature oyo emonanaka. Benda mpo na kobongola bonene. Finá na esika bakomi Bomba. Tozali kobimisa clé RSA-2048 ya sika + certificat oyo e signer yango moko na navigateur na yo, tosalaka calcul ya hash SHA-256 ya intervalle ya octet ya mokanda, to paqueter blob ya ba données signées PKCS#7, mpe to intégrer yango na PDF. Fisyé oyo otye sinyatili ezwamaka mbala moko.
Pourquoi Oyo Ezali Meilleur Signeur ya Gratuit PDF

Signatures électroniques vs. Signatures numériques — Oyo Ezali mpenza kosimba
Sinyatili ya elektroniki (SES — Simple) .
Elembo nyonso oyo emonanaka na mokanda ya nimero : nkombo oyo ekomamaki na masini, makomi oyo esalemi na masini, signature ya encre humide oyo esalemi na scanner, esika ya kotiya elembo "Nandimi". Endimami na mibeko na ba jurisdictions mingi mpo na mombongo ya mokolo na mokolo (EU eIDAS SES tier, US ESIGN / UETA, UK Electronic Communications Act) kasi pete mpo na kobunda soki signateur na sima aboyi ko signer — ezali na preuve cryptographique moko te ya nani abimisaki marque. Mode na biso "visible seulement" ebimisaka yango.
Signature électronique ya liboso (AES) .
Niveau ya réglementation ya eIDAS ya UE 2. Esengeli (a) koyeba na ndenge ya bokeseni moto oyo atie maboko, (b) kozala na nse ya bokonzi se moko ya mopesi maboko, (c) koyeba mbongwana sima ya botiami maboko, (d) kosalama na kosalelaka ba données oyo motiami maboko akoki kobatela na nse ya bokonzi na bango moko. Sortie cryptographique na biso (PKCS#7 likolo ya SHA-256 na RSA-2048 mpe clé privée oyo esalemi localement na stockage Web Crypto non extractable) ekokisaka ba critères nionso minei — okoki ko réclamer statut ya AES mpo na PDF oyo o signer awa.
Signature électronique oyo ekoki (QES) .
Niveau ya réglementation ya eIDAS ya UE 3. AES bakisa certificat qualifié ya Fournisseur ya Service ya Confiance (TSP) na liste ya confiance ya UE, bakisa dispositif ya création ya signature qualifié (HSM to smartcard). QES ekokani na mibeko na signature ya encre humide na UE mobimba. Tozali kobimisa QES te mpo ete ba flux ya navigateur kaka ekoki kokokisa te bosenga ya dispositif ya création ya signature oyo esalemi na matériel — osengeli na dispositif ya signature to HSM ya cloud oyo epesameli. Soki cas ya usage na yo esengi spécifiquement QES (contrats notarisés, quelques industries réglementées), osengeli na Adobe Sign, DocuSign EU Qualified, to TSP ya mboka.
Mibeko ya Etats-Unis (ESIGN / UETA) .
Mobeko ya fédéral ya Etats-Unis ESIGN (2000) mpe adoption ya UETA ya l’Etat etalelaka mingi ya ba signature électronique lokola oyo ekokani na mibeko na encre humide — kozanga scheme ya niveau ya UE. Mpo ete sinyatili ezala na nguya: (a) bato nyonso mibale basengeli kondima kotya sinyatili na nzela ya elektroniki, (b) sinyatili esengeli kozala na mokano, (c) esengeli kobatela mikanda. Nyonso wana ezali kosala; sortie na biso ekutanaka na bango. Mitindo mosusu ya mikanda ya sikisiki esalemi na mayemi (ba testaments, makambo ya mibeko ya libota, mwa ba dossiers ya tribunal) — tala état na yo.
