Practical ways to use this tool
Technical review
Compare a conversion result
Use the expanded PDF for technical inspection alongside the original document and rendered pages.
Researchers
Study PDF internals
Look at document objects and supported decompressed streams without mistaking them for a plain-text transcript.
Features and controls
Expand compressed PDF streams
Create a less compressed PDF representation for inspection or compatibility work.
Streams, objects and intended use
The converter uncompresses supported streams and disables object-stream packing. This can make low-level PDF structure easier to inspect with appropriate development tools. It does not extract an archive, make scanned words editable or increase image detail. The output remains a PDF.
Expect a larger file
Decompression trades compact storage for a more expanded representation.
File size and suitable alternatives
A larger output is normal and is bounded by the service’s output limits. Appearance may remain essentially the same even when the file size changes considerably. If your aim is a smaller email attachment or faster transfer, use Compress PDF instead. Preview the result before relying on it in another workflow.
Keep native page content
The operation works with PDF pages rather than screenshots.
Content quality and interactive features
Text and vector artwork remain in PDF form where supported. The original file on your device is not overwritten. Interactive forms, annotations, links and document-level navigation can behave differently in a newly assembled document, so check the generated PDF before sharing it. Page rearrangement is not redaction of information inside retained pages.
Review your finished PDF
Preview the result before downloading and sharing it.
Preview, download and revise
Select Start when the settings are ready. On the result screen, Preview opens the generated PDF and Download saves a separate copy. Back returns to the current workspace; Start over clears it for a new file. Review small text, page edges and page order in the finished copy. A new PDF does not preserve the validity of an existing digital signature.
Supported files & processing

- Output
Open one PDF up to 100 MB and 750 pages. Additional output, memory and processing limits can apply to complex documents.
Processing uses our servers. Source files, temporary files and results are deleted from our servers within 30 minutes after processing finishes. We do not share document contents with third parties or use them to train AI models.

FAQ
A few useful answers
Know what to expect before you start.
Temporary server processingWhat does PDF decompression actually do?
The converter uncompresses supported streams and disables object-stream packing. This can make low-level PDF structure easier to inspect with appropriate development tools. It does not extract an archive, make scanned words editable or increase image detail. The output remains a PDF.
Does uncompressing a PDF restore image quality?
A larger output is normal and is bounded by the service’s output limits. Appearance may remain essentially the same even when the file size changes considerably. If your aim is a smaller email attachment or faster transfer, use Compress PDF instead. Preview the result before relying on it in another workflow.
What are the file and page limits?
Open one PDF up to 100 MB and 750 source pages. Protected files need an unlocked copy unless this tool explicitly offers password entry. Large or complex pages can require more memory or reach processing limits even when the file is within these limits.
Where is my document processed?
This tool uses our servers for processing. Your original file is not overwritten; the result is a separate download. Preview and review the result where available, and download the copy you need before starting over.
