Free online tools for your pictures and PDFs

Pick the free tool for the file in front of you. The picture tools and PDF converters resize, shrink, or convert your file right in your browser. The PDF and image makers start from a designer-made template, so your invoice or certificate looks the part the first time you send it. None of them needs an account. Save the design, and your AI assistant or a spreadsheet makes every one after that for you.

    You already have the picture or the PDF and only need a new size, a smaller file, or another format.

  • Use a PDF or image maker

    You need one invoice, certificate, or post today, and you want it to look designer-made.

  • Save a design

    You'll make this file again and again, so you save it once and let your AI assistant or a spreadsheet make each one.

Questions about the free tools

You don't need an account for the free tools. The PDF and image makers give you up to 5 free files a day without one.

How do the 50 free credits work?

They come with a free account, 50 each month. When you're signed in, each PDF or image from a maker uses one, and the picture tools and PDF converters never use any. Free credits you don't use are gone when the next 50 arrive. Without an account, the makers still give you up to 5 free files a day.

Can I earn more credits?

Yes. Make your first file in Studio, then earn 500 credits for an approved 18-question survey. Sign in to see the offers. Start free.

Do my pictures get uploaded?

No. The picture tools and the PDF converters work inside your browser, so your picture or PDF stays on your computer. The PDF and image makers send the details you type, and any photo you add to the design, to thirds.ai to make your file.

Can my AI assistant make the next invoice for me?

Yes. Pick a template in the gallery, click Use this template, and save it with your brand on it. Then ask ChatGPT or Claude for each new invoice in plain words, and the finished PDF lands in the chat.
