Free online tools, no sign-up required
Chatzam brings together the everyday tools everyone needs at some point: sign or merge a PDF, convert an iPhone photo, shrink an image, trim a video, extract audio from a clip, transcribe a recording, or test your mic before a video call. They're free, require no sign-up, and work on both computer and mobile.
Your files stay on your device
Most of these tools run directly in your browser thanks to open-source technologies (pdf.js, pdf-lib, FFmpeg, OCR, speech recognition). Your documents, photos, videos, and recordings are then never sent to our servers: it's faster, and much safer for your personal data. AI tools and tools that start from a link say so on their page: the text or link is sent to be processed, then nothing is kept.
Also available: free AI assistants
Alongside these tools, Chatzam offers dozens of free AI assistants for writing, summarizing, translating, or learning, with no account required.
Frequently Asked Questions
Are Chatzam's tools really free?
Yes, completely free and with no sign-up. The site is funded by advertising.
Are my files sent to a server?
For most tools, no: they process your files directly in your browser, and only the processing engines (for example FFmpeg or the speech recognition model) are downloaded, then cached. AI tools and tools that start from a link are the exception and say so on their page: the text or link is sent to our server to be processed, then nothing is kept.
Do the tools work on phones?
Yes, most work on smartphones and tablets. The screen recorder requires a computer, since mobile browsers don't support screen capture.
Is there a limit on file size or number of files?
There's no quota. The only limit is your device's memory, especially for very large videos.
