Compress PDF Online Free — Best Tool for China Users
Compress PDF online free — trusted by Chinese users. Works for GSXT, tax bureaus, and Chinese administrative platforms. Meet upload limits for 税务申报表 tax forms, 身份证 copies, and 营业执照 business licenses. No signup, no watermark.
Chinese users increasingly manage 税务申报表 tax forms, 身份证 copies, and 营业执照 business licenses and other documents via WeChat and mobile apps, and large PDFs create real problems — slow uploads, rejected submissions, failed shares. Our free compressor is optimised for China mobile connection speeds. Open the tool in any browser, upload your PDF, and download a compressed file ready for GSXT, tax bureaus, and Chinese administrative platforms or any other China platform. Three compression levels — low for maximum quality, medium for the best balance, high for the smallest file size — give you full control without installing anything. All files are processed over an encrypted HTTPS connection and permanently deleted within 1 hour of upload. No data is retained on our servers, no content is ever accessed by staff, and no information is shared with third parties — fully consistent with PIPL (个人信息保护法) data minimisation principles.
