Electronic signatures and digital certificates allow to sign JPEG document with eSign application. Note, the signed JPEG document keeps signatures as supported document elements, such as text, labels, stickers, images, hidden metadata information and digital certificates that verifies document content. The JPEG document signed with digital certificates could be verified for any changes of its content. If there were some changes made to signed document then verification process will detect it and certificates will be not valid. To add various electronic signatures, you need to select one or more JPEG documents, then in application select one from the existing signature templates like Text Stamps, Images, Handwritten signatures, Barcode, QR Code or digital certificate to sign, drag the signatures across the document pages. The documents are stored in a secure storage. You can upload it from any platform, mobile or another device, on any Windows, MacOs, Linux or Android platform. We support any browser and provide generation of any digital signatures, metadata signatures or certificates. No registration is required. All files are processed on our servers so no additional plug-ins or software installations.

JPEGJPEG Image
A JPEG is a type of image format that is saved using the method of lossy compression. The output image, as result of compression, is a trade-off between storage size and image quality. Users can adjust the compression level to achieve the desired quality level while at the same time reduce the storage size. Image quality is negligibly affected if 10:1 compression is applied to the image. The higher the compression value, the higher the degradation in image quality. JPEG image file format was standardized by the Joint Photographic Experts Group and, hence, the name JPEG. The format has been the choice of storing and transmitting photographic images on the web. Almost all Operating systems now have viewers that support visualization of JPEG images, which are often stored with JPG extension as well. Even the web browsers support visualization of JPEG images.
The digital signature is an electronic artifact on the document which could be a simple document element like a text, stamp, image or could be a more complicated digital certificate that verifies the document signer and checks that document data was not changed after its signing.
❓ How to create a digital signature?
Once you will upload the document from this page, you will be redirected to the document editor where you will need to pick the signature type that could be text, image, stamp, barcode, QR code or digital certificate. When the signature type is selected you can click [Add] button to create a new digital signature of the proper type. Text signature requires only text and adjusting its style. Image signature requires the image to be uploaded. Barcode or QR code signature requires text. The digital certificate will need a special pfx certificate file to create the documen signature.
❓ How to sign a JPEG document?
The document could be signed with many electronic signatures of the different types. The signatures could be added to the document page and then could be saved. Some documents support only simple electronic elements like text and images. Many documents formats support digital certificates that allow protecting content from unexpected changes.
❓ How to add signature?
Simple digital signatures, like text and images, could be located on the document page to provide a visual signature confirmation. When the document was uploaded to the editor the signatures from the toolbox could be dragged to the document page and pointed to a specific area. The digital certificate could have no visual representation but be embedded into the document and protect it from unexpected changes.
❓ How to verify a signature in JPEG document?
The digital signature on the document could be verified visually or automatically. Visual verification is efficient for text, stamps, handwritten signatures, watermarks. The automatic verification could tell hidden information about the document signer and protect the document from unexpected changes. The Barcode and QR code signatures allow automate document verification process. Digital certificates could protect highly important documents from unauthorized changes.
