When this tool is useful
Testing whether an unsigned, untagged, noninteractive, non-linearized simple PDF benefits from a verified object-stream rewrite.
How local processing works
The parser refuses signed, already-linearized, interactive, tagged, outlined, annotated, attached, or automatic-action documents, saves an object-stream rewrite, reopens it, and compares physical page count, crop boxes, rotation, and byte size.
How to use it
- Prepare a safe working copy: Keep every source unchanged and review the supported input, controls, and limits before processing. Testing whether an unsigned, untagged, noninteractive, non-linearized simple PDF benefits from a verified object-stream rewrite.
- Process locally: Run the documented operation in this browser and stop if an unsupported structure is reported. The parser refuses signed, already-linearized, interactive, tagged, outlined, annotated, attached, or automatic-action documents, saves an object-stream rewrite, reopens it, and compares physical page count, crop boxes, rotation, and byte size.
- Download and verify: Compare source and output byte sizes, render every page in target viewers, confirm crop boxes and rotation, and use a dedicated linearization checker if Fast Web View is actually required.
Important limitations
This does not create or claim true byte-range linearization or Fast Web View. It does not recompress images, stream pages progressively, preserve unsupported advanced structures, or guarantee that the output is smaller or faster.
Verify the downloaded result

Private by design

What does the browser actually do?
The parser refuses signed, already-linearized, interactive, tagged, outlined, annotated, attached, or automatic-action documents, saves an object-stream rewrite, reopens it, and compares physical page count, crop boxes, rotation, and byte size.
Which limits must I understand?
This does not create or claim true byte-range linearization or Fast Web View. It does not recompress images, stream pages progressively, preserve unsupported advanced structures, or guarantee that the output is smaller or faster.
How should I verify the result?
