When this tool is useful
Creating fixed-pixel previews, archive derivatives, slide images, or compatibility copies when selectable text and vector structure are not required.
How local processing works
PDF.js validates and renders every physical page at a bounded scale into a fresh canvas. The browser encodes each canvas in the chosen raster format and packages all outputs in page order.
How to use it
- Prepare and preserve the source: Keep the unchanged source, review the intended destination, and begin with conservative limits. Creating fixed-pixel previews, archive derivatives, slide images, or compatibility copies when selectable text and vector structure are not required.
- Run the bounded local operation: Process only in this browser and stop on unsupported, malformed, or ambiguous input. PDF.js validates and renders every physical page at a bounded scale into a fresh canvas. The browser encodes each canvas in the chosen raster format and packages all outputs in page order.
- Inspect the result: Open representative first, middle, and last images at 100%, compare page count, crop, rotation, color, small text and transparency with the PDF, and preserve the original PDF.
Important limitations
Rasterization permanently removes selectable text, links, forms, annotations, signatures, layers, vectors, accessibility structure, and print precision. It does not unlock encrypted files or prove archival compliance.
Verify the downloaded result
Open representative first, middle, and last images at 100%, compare page count, crop, rotation, color, small text and transparency with the PDF, and preserve the original PDF.
Private by design
Your files stay in this browser. The tool does not upload the source or output to our servers.
