How to convert AI to PDF
Adobe Illustrator files (.ai) are the working format for vector graphics created in Illustrator. They preserve editable paths, layers, and type, but they require Illustrator to open. Converting an AI file to PDF produces a document that any PDF viewer can open while keeping vector sharpness at any print size.
BoltConverter sends your AI file to its conversion server, renders it to PDF, and returns the download link. Your file is deleted from the server immediately after conversion. No Adobe software is needed on your end.

Frequently asked questions
Will the PDF keep vector quality?
Yes. AI files contain vector data, and the PDF output preserves that, so text and paths stay sharp at any zoom level or print size.
Do I need Adobe Illustrator installed?
No. BoltConverter handles the conversion on its servers. You only need a browser.
Are layers preserved in the PDF?
Standard PDF output flattens the file. All artwork is visible, but Illustrator-specific layers are not retained as editable layers in the PDF.
What is the maximum file size?
The server accepts files up to the displayed limit on the upload page. AI files for typical print and web projects fall well within this range.
Is my AI file kept private?
Your file is uploaded over HTTPS, processed, and then deleted immediately after the PDF is ready. It is not stored or used for any other purpose.
