AI to PDF: the format that was already PDF

Since Illustrator 9, a .ai file saved with PDF compatibility on is a PDF, the same syntax, with Illustrator’s private data in a section readers ignore. That makes this the lightest conversion on the site: the artwork stays vector, fonts and paths survive, and nothing is rasterised. Files saved with PDF compatibility switched off are not readable this way and need Illustrator.

Convert to hand artwork to a printer or client who cannot open .ai, keeping it resolution-independent. Keep the .ai as your working copy, the layer and editability data is in the part a PDF reader discards.

Frequently asked questions

How to combine multiple AI photos into one PDF document

Upload all your AI images to iFormat at once. Each image is placed on its own page and combined into a single PDF in upload order. No account is required, and the result is a multi-page PDF.

Will my AI image quality be preserved in the PDF?

Yes. Each AI image is embedded at its source resolution and scaled to fit the page while keeping its aspect ratio, so the PDF stays print-ready and sharp.

Can I convert scanned AI pages into a searchable PDF?

The converter creates a PDF with your AI images embedded as-is, visually identical to the originals. For searchable text over those scans, use iFormat's OCR tool after conversion to add a text layer.

How to turn AI receipts or documents into a PDF for email

Upload the AI photos of your receipts or documents and iFormat combines them into a single, clean PDF file. Each image becomes one page, making it easy to attach to an email or submit to an expense report without sending loose image files.

How do I open AI files?

On Windows: Illustrator; Photopea or Inkscape otherwise. Renaming to .pdf often opens it in a PDF reader. On a Mac: Illustrator; Preview opens most AI files because they carry a PDF stream. Most AI files are saved PDF-compatible, which is what lets other software read them. Files saved with that option off will not open outside Illustrator.
