How to sign a PDF online for free
Open your PDF in Samarin Sign, select Text and tap the place where you want to type. Add a name, address or a short answer, then choose Signature to draw with your finger, mouse or stylus. Move the signature into position, adjust its size, review every page and download the finished PDF. No registration, subscription or watermark is required.
Fill in a PDF form without printing
You can add text to a PDF even when it has no interactive form fields. This is useful for applications, scanned forms, agreements and other documents you are authorised to complete. The date and checkmark tools help with common fields. Choose Arial, Serif or Mono, set the text size and colour, and move each added item until it fits.
A signature from your phone or computer
Draw on the signature pad with a finger or mouse. With a compatible stylus you can enable pressure sensitivity and adjust pen width. You can also type your name to create an italic signature. The same editor works on a desktop, tablet or phone; the interface can switch between English, Hebrew and Russian without reloading your document.
White marker: cover an area before adding new text
Use the white marker for freehand strokes or the white rectangle for a larger area. Then place text over the covered area if needed. Zoom in and inspect the edges carefully. White is best suited to white page backgrounds. The downloaded PDF contains images of the completed pages, so the original text beneath a covered area is not retained as a separate text layer. This is not a certified redaction service; incomplete coverage can still reveal information.
Files, privacy and the exported PDF
The editor processes your selected file and signature in browser memory; it does not upload them to our server. It does not save your project automatically. Download the result before closing the page and keep the original. Editor libraries are loaded through jsDelivr, which receives ordinary connection information, not your document. General site browsing is covered by our Privacy Policy.
The result is an image-based PDF. Original searchable text, links, editable form fields and certificate-based signatures are not preserved. Files up to 25 MB and 50 pages are supported; performance depends on your device. DOCX import is experimental and may change the layout. For predictable results, export Word documents as PDF first.
Is this a digital signature?
Samarin Sign places a visual signature on a document. It does not verify identity, issue a certificate or provide a signing audit trail. If a recipient requires a certificate-based digital signature, use an appropriate service. Acceptance depends on the document, recipient and applicable requirements.
Fill and sign images, then choose a download format
You can open PNG, JPEG and WebP images, as well as GIF, BMP, AVIF and simple SVG supported by your browser. Select several images to create a document with one image per page. Animation is imported as a still image; large pictures are optimised for browser memory. PDF remains the default download. You can also choose PNG, JPEG or WebP: save the current page, or all pages in one ZIP file. The editor works locally and does not upload your selected images.
Keep Samarin Sign on your home screen
Open the editor in a full window and tap the install icon. A supporting browser can add Samarin Sign to your home screen or desktop as an app. On iPhone, use Safari’s Share menu and Add to Home Screen. The shortcut opens the tool; it does not save a project or document. An internet connection is needed to launch the editor and load its libraries.
Scan a paper document with your phone
Choose Scan document next to Upload. Take a photo with your phone camera or select an existing photo. The scanner can suggest the edges of a light sheet against a contrasting background; check and adjust the four corners. Straighten the page and choose enhanced colour, grayscale, black and white or original colour. Add more pages, then open them in the editor to fill in text, add a visual signature and download PDF by default, or PNG, JPEG or WebP.
Scanning is processed locally in your browser, without uploading the photo. It does not perform OCR or authenticate a document. Camera availability depends on your device and browser; the photo chooser remains available. Scans open as a new document, so download any current work first.
How to scan multiple pages into one PDF
Choose Scan document, then take a photo of the first page or choose an existing image. Check the corners, straighten the page and select Add this page. Next, choose Scan next page or Choose next photo. Repeat for each page. When all pages are ready, open the scans in the editor, check their order and download one multipage PDF.
Convert photos to PDF and choose your file name
Existing photos can also be selected through the normal upload button: each image becomes a separate page. Use the scanner for cropping and perspective correction. When you finish editing, open Review and download and edit the File name field. The suggested name includes Samarin Sign, and you can replace it completely. The correct PDF, PNG, JPEG, WebP or ZIP extension is added automatically.
Questions about filling and signing PDFs
Can I scan a document online for free on my phone?
Yes. Choose Scan document, take a photo or select an existing image, adjust the corners and straighten the page. Open the scan in the editor and download a PDF. Camera availability depends on the browser.
Can I scan several pages into one PDF?
Yes. Add the pages one at a time. After each page, scan the next one or choose another photo, then download all added pages as one PDF.
Can I rename the downloaded file?
Yes. Change File name in the Review and download window. The finished name appears below the field, and the selected format extension is added automatically.
Can I sign a PDF online for free?
Yes. You can add text and a visual signature, review the document and download it without an account or watermark.
Can I add text to a scanned PDF?
Yes. Added text is placed over the page image. The tool does not rewrite or recognise the existing text.
Are my documents uploaded?
The editor processes documents and signatures locally in your browser and does not send them to our server. Technical library downloads and ordinary site browsing are described in the Privacy Policy.
Can I import a Word document?
DOCX import is experimental. Layout may differ from Word. Check every page or export the file as PDF in Word first.
Does the white marker delete information?
It covers the selected pixels in the image-based export. Check that the entire area is covered; the tool is not a certified redaction service.
Where is the signed PDF saved?
Use Review & download, check the document and create the PDF. Your browser saves the file to its Downloads location or offers a save/share dialog.
Use only documents you are authorised to edit or sign. You are responsible for the information entered, permissions and checking the result and recipient requirements. The tool provides no legal advice or guarantee that a document will be accepted. To the extent permitted by law, the Studio is not responsible for losses resulting from misuse, inaccurate input or reliance on an unchecked result. This does not exclude liability or rights that cannot lawfully be excluded. Use is optional; if unsuitable, do not use it. Suggestions or a problem? Contact us at the details below.
