What Scan to PDF helps you do

Use your device camera to capture paper pages and assemble them into a single PDF, all in the browser. It is a phone-friendly way to digitize a form, receipt or note without a dedicated scanner. Each capture becomes one PDF page sized to the captured image.

Scans are captured and assembled in your browser. Images are not uploaded to Haivix servers.

How it works

A PDF stores positioned drawing instructions rather than flowing paragraphs, which is why editing one is different from editing a document. Page content, fonts, images and annotations are separate objects, and a page only carries a text layer if the producer wrote one. Most tools here rebuild or render the file in your browser with pdf-lib and pdf.js; the formats that need a full office engine, such as Word, Excel, PowerPoint, PDF/A and HTML, use the Haivix service and say so in their privacy note. Every tool writes a new file and leaves the original untouched. Because content is placed by coordinates, extraction often returns text runs in visual order rather than sentences, and columns or tables can arrive interleaved.

How to use Scan to PDF

Open the tool on a device with a camera and allow access.
Point the camera at the page and capture each shot.
Check the thumbnails and recapture any page that is unclear.
Create the PDF and download it.

When to use it

Digitize a signed form or receipt with your phone.
Capture several pages into one PDF for filing.
Turn paper notes into a shareable document.
Photograph a whiteboard and send it as a PDF.
Collect a few pages while away from a scanner.
Create a quick visual record of a document.

When not to use it

Do not expect OCR; the pages are images, not searchable text.
Do not use it for archival-quality scans; a flatbed scanner is better.
Do not expect automatic edge detection or perspective correction.

Example

Two captured pages are assembled into a single two-page PDF on the device. Each page takes the pixel dimensions of the capture, so a 1280 by 720 image becomes a page of that size rather than A4. The JPEG is embedded at high quality, and the original photos are not uploaded anywhere.

What you can do with Scan to PDF

Start the device camera from the page.
Capture one page per shot.
Preview the captured pages as thumbnails.
Assemble the captures into one PDF.
Embed each capture as a JPEG image.
Run the whole process locally.

Example: work on a copy and check the output

Keep the original file. These tools produce a download rather than editing in place, so a failed operation never damages the source.

Check whether the PDF has a real text layer before relying on extraction. A scan is an image, so text tools return little or nothing until OCR has run.

Unlock encrypted files first. A password-protected PDF cannot be reordered, cropped or annotated until it has been opened with the correct password.

Review the output before sending it on. Fonts can substitute, overlays do not always remove what is underneath, and page boxes can shift content near the edges.

Note the page size and orientation before laying anything out. A mixed document can contain portrait and landscape pages, and a tool that assumes one size may crop or offset the others.

Keep a note of the operation and its settings. If a recipient questions the result, reproducing it from the original is faster than guessing which options were used.

What to know before you start

Capture quality depends on the camera and lighting, and there is no automatic page-edge detection like a dedicated scanner app.
Camera access requires a compatible browser and permission.
Pages are images only, with no OCR or text layer.
Page dimensions follow the capture, not a standard paper size.

Common mistakes

Capturing at an angle and expecting the page to be straightened.
Assuming the output is A4 or Letter; it follows the image size.
Expecting selectable text.
Using a browser that blocks camera access or a page served over plain HTTP.

Troubleshooting

If the camera does not start, check permission and use HTTPS.

If the capture is dark, improve the lighting rather than increasing exposure later.

If a page is missing, it may not have been captured before creating the PDF.

If the PDF is large, the captures are large images; retake at a lower resolution if the camera allows.
