BROWSER-ONLY PDF TOOLS
A smaller PDF, if possible.
Reduce PDF structure overhead without resampling images or turning text into pictures.
No file upload. No account. No watermark.
Open a PDF on your device
PDF only · up to 20 MB · 100 pages. The file stays in this tab.
Structural optimization only. Image resolution stays unchanged; size savings vary.
Replace this PDF?
Your unsaved signature placements will be cleared. The original file on your device stays unchanged.
What stays private?
This tool reads and processes the PDF in your browser. It does not upload the file or signature to DocAISign. Close the tab to clear its in-memory copy; downloaded files remain on your device. Local processing and privacy.
Why might the size stay the same?
Much of a PDF may already be compressed. If the rewritten PDF is not smaller, we offer your original file instead. Savings and processing time depend on the file and device.
Which files work?
Ordinary PDFs within the limits above. Password-protected files, XFA forms and PDFs with existing signature fields are not supported here. Keep the original and review every output.
