How to use Image to PDF
A clear browser-session workflow for convert PDF work.
The interface should make the route visible: select files, perform the operation, and download the output from the same session.
02
Choose page size
Select A4, Letter, or Fit to image. The engine scales and places images on the chosen page size.
03
Generate PDF
The PDF is created in your browser using local processing and prepared for direct download.
Why local processing matters
Compare the processing route before using sensitive documents.
DocuStitch labels supported workflows around the browser session rather than hiding the path behind a generic cloud promise.
DocuStitch supported workflow
- Files selected on device
- Operation runs in browser session
- Output downloads from the tab
Typical cloud workflow
- Files uploaded to remote queue
- Processing depends on server retention policy
- Output returned after transfer

Operator notes
Convert images to PDF in your browser
Converting images to PDF is useful for receipts, portfolios, homework, and document bundles. Many converters require uploading photos before creation. DocuStitch removes that step for standard workflows.
When you select JPG, PNG, or WebP files, they are processed directly in browser memory. The engine arranges them into PDF pages using local device resources.
This local-first flow is useful for images that contain IDs, financial paperwork, or other sensitive material.
01
On-device engine
Conversion logic runs in your browser using local processing.
02
Privacy focused
For standard workflows, no third-party file upload step is required.
03
Flexible page sizing
Choose A4, Letter, or fit-to-image output based on your use case.
04
Instant export
The PDF is created locally without a remote upload/download cycle.
FAQ
Frequently asked questions

How many images can I convert at once?
That depends mostly on your device resources and browser session limits.
What image formats are supported?
Common web formats such as JPG, PNG, and WebP are supported.
