About this tool
A focused utility built for a single recurring document task. Rewrite PDF objects in classic layout — friendlier for editors and parsers. Processing runs locally in your browser's memory — the document is never transmitted, and closing the tab clears it completely. The workflow is deliberately short: load the file, choose the options on the page, run the operation, and save the result. Every choice is applied before the file is written, so re-running with different settings takes seconds. Practical limits apply (files up to 10MB), and it pairs well with the related tools linked beside this page when one step is not the whole job. Key facts — Processing: runs entirely in your browser, client-side; Access: free with no account required; File limits: files up to 10MB; Privacy: the file never leaves the device. Measured on the exact production pipeline: fully expanding object streams of a 60-page text PDF takes ~16 ms at the median.

FAQ
Will my file be uploaded?
No. Everything runs locally in your browser — your file is never uploaded and is cleared upon closing the page.
Are there any limits?
Expanding object streams may increase the output file size; files must be ≤ 10MB.
Will my original file be modified?
No. The tool reads your file and produces a new one — the original stays untouched.
Can I process multiple files in bulk?
A single tool page handles one task at a time; for bulk work use the Batch Processing workflow and add this tool as a step to run a whole set at once.
Is the processed file still editable?
The output is a standard PDF with uncompressed object streams; the original stays intact and you can edit the new file in any editor.
