Adobe Illustrator files (version 9 and later) contain a full embedded PDF layer. This tool extracts it in a single click — no conversion, no quality loss, no rasterisation.

💡
How AI to PDF Extraction Works
Since Adobe Illustrator version 9 (released in 2000), every .ai file contains a fully embedded PDF compatibility layer. This tool scans the binary file for the embedded %PDF- marker, extracts the native PDF bytes, and downloads them — preserving all vector artwork, fonts, and layers at 100% quality with no re-encoding or rasterisation.

How It Works

Native PDF Extraction
— Zero Quality Loss

No re-rendering, no rasterisation, no compression artefacts. The extracted PDF is the same native vector data Adobe Illustrator embedded when the file was saved.

🔍
Binary %PDF- Scanner
The tool reads the .ai file as a binary ArrayBuffer and scans for the %PDF- signature byte sequence that marks the start of the embedded PDF layer.
🎯
Lossless Extraction
PDF bytes are sliced from the binary file exactly as Illustrator wrote them — no re-encoding, no rasterisation. All vector paths, fonts, and embedded images are preserved identically.
👁️
Live Preview in Browser
The extracted PDF is loaded into a sandboxed iframe using a Blob URL, letting you preview every page of the artwork before downloading.
📊
PDF & AI Version Detection
The tool reads the PDF version string and scans the PostScript preamble for the Illustrator version that created the file, showing both in the stats panel.
📑
Page Count Detection
The extracted PDF bytes are scanned for the /Count field in the Pages dictionary to show how many pages the artwork contains.
💾
Size Comparison
Shows the original .ai file size versus the extracted PDF size so you can see how much space the AI-specific metadata overhead was taking.
🔒
100% Private
Your .ai file is read entirely in your browser. It is never sent to any server. The extraction and download happen locally on your device.

FAQ

Frequently Asked Questions

Common questions about converting Adobe Illustrator AI files to PDF.

Does the converted PDF lose quality?
No. The tool extracts the PDF bytes that Illustrator embedded natively. There is zero re-encoding or rasterisation — the PDF is identical to what Illustrator would produce when exporting directly.
Is my .ai file uploaded to a server?
No. The file is read entirely in your browser as a local binary buffer. Nothing is sent to any server. Your artwork stays completely private on your device.
Which AI versions are supported?
Adobe Illustrator version 9 and later (from the year 2000 onwards). All modern .ai files include an embedded PDF layer. Files from Illustrator 8 or earlier use legacy PostScript format and are not supported.
Will layers and artboards be preserved?
The extracted PDF contains whatever Illustrator embedded in the PDF compatibility layer, which typically includes all artwork, fonts, and embedded images. Editable AI-specific layers are not part of the PDF layer.
Why is the PDF smaller than the .ai file?
Modern .ai files contain both a PDF layer (for compatibility) and separate AI-specific metadata, history, and editing data. Extracting the PDF layer removes the AI overhead, resulting in a smaller file.
What if the file says "Legacy AI File"?
The file is an older Illustrator version 8 or earlier file with no embedded PDF. Open it in Adobe Illustrator or Inkscape and use File → Save As PDF or Export → PDF to convert it manually.
