PDF to Curves
On-deviceConvert every font in a PDF to vector outlines (curves / 转曲) for print shops, right on your device. The tool verifies the result pixel-by-pixel — nothing is uploaded to a server.
About this tool
What you provide
- One or more PDF files whose fonts should become outlines.
What you get
- A PDF with every font converted to vector curves.
- A verification line: the fonts found reduced to zero, the pages verified, and the ink-match percentage.
Limits
- Files up to 100 MB.
- Needs a one-time download of the roughly 12 MB engine before the first run.
- Form fields and annotations are flattened, so their appearance may change.
- If the converted file fails the pixel comparison against the original, it isn't delivered.
How to use it
-
Add your PDFs
Drop PDFs on the box or tap it to choose them; add as many as you need and remove any with the × button.
-
Download the engine once
On the first run tap "Download engine (~12 MB · one time)"; your device keeps it, and the "Convert to curves" button takes its place.
-
Convert to curves
Tap "Convert to curves" — every font is turned into outlines and the result is compared against the original page by page.
-
Check the proof and save
Read the line showing fonts reduced to 0, pages verified and the ink-match percentage, then save the file, or take several as one ZIP; a file that fails the comparison is not handed over.
Frequently asked questions
What does converting PDF fonts to curves or outlines do?
It turns the text in your PDF into vector outlines, so the file prints and displays correctly on any device even without the original fonts installed.
Why would I need to outline fonts in a PDF before printing?
If the printer or recipient doesn't have your fonts installed, outlining them into curves keeps the exact look of your text in the printed file.
Is converting a PDF to curves free, and does it upload my file?
Yes, it's free, and the conversion runs on your device, so your PDF isn't uploaded anywhere.
