Convert documents, in one place
Slides, reports, spreadsheets, PDFs and images — convert between the formats you actually use. No sign-up, no watermark, and every uploaded file is deleted automatically within 30 minutes.
The converter interface is currently available in Chinese.
Three conversion paths
One service, three focused tools — each built for a specific document workflow.
Office → PDF
Convert PPT, PPTX, DOC, DOCX, XLS, XLSX plus ODP/ODT/ODS to standard PDF. Server-side layout rendering keeps fonts and page order. Batch up to 5 files and merge them into a single PDF.
Open the tool → Path 02PDF → PPT
Render every PDF page at high resolution and rebuild it as a 16:9 .pptx deck — a practical way to turn existing documents into presentation material.
Open the tool → Path 03PDF → Images
Export pages as PNG or JPG at 96, 150 or 300 DPI. Multi-page files are packaged into a single ZIP automatically.
Open the tool →How it works
Three steps, no account required.
1. Pick a path
Choose Office → PDF, PDF → PPT or PDF → Images on the converter page.
2. Upload your files
Up to 5 files per run, 20 MB each. Merge multiple documents into one PDF if needed.
3. Preview and download
Review the result in the browser, then download each file or the whole ZIP.
Privacy by default
Uploaded files and converted results live in a temporary directory and are deleted automatically within 30 minutes. Download links use random, unguessable file names. We do not analyse, share or train models on your documents, and the site carries no third-party tracking or advertising scripts.
Limits, stated plainly
20 MB per file, up to 5 files per run, and PDF → PPT/images works best under 50 pages. Password-protected documents must be unlocked before uploading, and scanned documents that need OCR are outside the scope of the service.
Frequently asked questions
Is it free?
Yes. All three paths are free, with no sign-up and no watermark.
What happens to my files?
They are used only for the conversion you requested and deleted within 30 minutes. See the privacy policy (Chinese) for details.
Why is the interface in Chinese?
Fangceng is operated for a Chinese-speaking audience. The converter itself is language-agnostic — upload a file and download the result, no reading required beyond the buttons.
Can I integrate this into my own system?
For batch or integration needs, email us with your scenario and volume.
About Fangceng
Fangceng (fangceng.com) is an independent online document conversion brand. We keep the tool quiet and straightforward: open the page, drop in a file, get a properly rendered document back. Documents are produced by a server-side layout engine, so the output contains selectable, searchable text rather than screenshots.
