About this tool
Designed for the moment you need a document changed quickly and privately. Check a PDF's exact file size, page count and whether it contains images, to decide if compression is needed. 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), 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: see the on-page limits; Privacy: the file never leaves the device.

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?
Checking size does not modify the file; it is a read-only inspection.
What details are included in the inspection result?
The tool reads the PDF structure directly in your browser and shows the file size formatted as KB/MB (read exactly from the underlying bytes), along with the page count, PDF version, and whether pages contain images — no conversion or estimation involved.
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?
This tool only displays metrics on the page without generating any new output file; your original document remains completely untouched.
