About this tool
A focused utility built for a single recurring document task. Scale all pages to A4/Letter/A3/A5, centered and aspect-safe. 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 (see the on-page limits); 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: see the on-page limits; Privacy: the file never leaves the device.

FAQ
Will my file be uploaded?
No. Processing runs entirely in your browser — your file is never uploaded, and closing the page clears it immediately.
Are there any limits?
Pages are scaled proportionally without stretching; files up to 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 reorganized new PDF; the original stays intact and you can re-run as many times as you like.
