When this tool is useful
Pages with line art, UI screenshots, diagrams, or small text that benefits from lossless PNG encoding.
How local processing works
Each selected page is rendered to a canvas at the chosen scale and exported as PNG without a server upload.
How to use it
- Choose the source files.
- Review the available settings and page order.
- Process locally, inspect the result, and download it.
Important limitations
PNG pages can be much larger than JPG, and converted text is still rasterized rather than editable.
Verify the downloaded result
Reopen the downloaded file in its destination application, check dimensions or page count and visible content, and keep the source until the result has been accepted.
Private by design
Your files stay in this browser. The tool does not upload the source or output to our servers.
Questions and answers
Does this tool upload my files?
No. Processing happens in your browser; closing the page clears the working session.
Will the output always match the source exactly?
PNG pages can be much larger than JPG, and converted text is still rasterized rather than editable.
What should I check before using the result?
Reopen the downloaded file in its destination application, check dimensions or page count and visible content, and keep the source until the result has been accepted.
Which browsers and devices are supported?
Use a current browser with JavaScript, workers, canvas, WebAssembly where the format requires it, Blob downloads, and enough memory. Reopen important downloads in the destination application.
Concrete input and output example
Input a one-page vector diagram and render it at 2× to PNG. Lines stay visually crisp, but the output is a raster image with no selectable labels and can be larger than JPG.
Browser compatibility notes
Reviewed against the implementation and required web APIs on 2026-08-12. Use a current browser where these APIs are available and verify important output on your device.
- Chrome / Edge (current desktop)
- Requires local PDF parsing, worker/canvas APIs where applicable, document creation, and Blob download.
- Firefox (current desktop)
- Uses the local PDF workflow; always verify the generated download in its destination viewer.
- Safari (current desktop)
- Uses the same local workflow; large page sets can have a lower practical memory ceiling.
A tool-specific question
Does PNG preserve PDF vectors?
Only their rendered appearance at the selected scale. The output contains pixels, not the original vector paths or selectable text.
