About AtlasDocs
1What is AtlasDocs?
AtlasDocs is a free web platform that brings together dozens of document tools — PDF, Word, Excel, PowerPoint, images, audio, video, spreadsheets, archives and much more. Best of all, everything runs right in your browser.
2Is AtlasDocs free?
Yes. Every tool is free and you don’t need to create an account.
3Do I need to install anything?
No. Just open the site in your browser; nothing is installed on your device.
4Does it work on phones and tablets?
Yes. Because everything runs in the browser, it works the same on desktop, tablet and phone.
5Is AtlasDocs on LinkedIn?
Yes. Follow the AtlasDocs page on LinkedIn to keep up with new tools and platform news.
Privacy and security
6Are my files sent to a server?
For most tools, no. The processing happens in your browser, on your own device. Therefore, your files never leave your machine.
7Are there exceptions that use a server?
Yes, a few. Opening and converting Office files and some heavier converters run on a server. In those cases, we clearly say so on screen and discard the file right after use.
8How do I remove hidden data before sharing?
Use the Security and Privacy category. The options “Clean before sharing” (PDF), “Clean image”, “Clean Office document” and “Clean audio/video” strip metadata and location.
9Can I hide sensitive information in a PDF?
Yes. The “Redact” tool covers and permanently deletes the content, leaving no text hidden under the mark.
10Can I protect a file with a password?
Yes. You can password-protect PDF, Office files and ZIP/7z. Likewise, you can also remove the password when you have permission.
11What does “Remove AI mark” do?
It removes the content credential (C2PA) that makes some social networks flag your photo as “made with AI”.
12How do I get notified about new guides and tools?
On the AtlasDocs blog, click “Follow the blog” and accept the browser prompt. That's it: you'll get a notification whenever we publish a new guide or improve a tool. It's free and asks for no email or sign-up. The subscription stores only what is needed to deliver the alert: the technical address your browser uses to receive the notification, the two keys that protect the delivery, the language you read the site in, and the date you subscribed. To stop, click “Unfollow” in the same spot. On iPhone and iPad, alerts only work if you add AtlasDocs to your Home Screen (Share → Add to Home Screen).
PDF tools
13How do I merge or split PDFs?
Use “Merge” to combine several files and “Split” to separate them. In addition, you can extract, delete, reorder, rotate and number pages.
14How do I make a PDF smaller?
Use “Compress”. It reduces the file size while keeping it easy to read.
15How do I convert a PDF to Word, PowerPoint or image?
Use “PDF → Word”, “PDF → PPTX” or “PDF → image”. You can also extract the text and convert to Markdown or EPUB.
16How do I create a PDF from another file?
Use the converters in the Create PDF category: Office → PDF, Text → PDF, Markdown → PDF, HTML → PDF, EPUB → PDF and more.
17How do I sign, highlight or watermark a PDF?
In the Edit PDF category you can sign, add text, insert an image, create a header and footer, highlight passages and apply a watermark.
Images, video, audio and data
18Which image tools are available?
You can convert format, compress, rotate and flip images, plus transform HEIC, TIFF, AVIF and SVG. You can also combine several images into a PPTX.
19How do I open an iPhone photo (HEIC)?
Use “View image” to open the HEIC right in the browser, or “HEIC → JPG” to convert it.
20What can I do with video and audio?
You can convert video to MP4, extract the audio (MP4 → MP3), convert audio to MP3, join videos, add a soundtrack and build a slideshow.
21I work with spreadsheets and data. What does AtlasDocs offer?
Plenty: Excel ↔ CSV, CSV ↔ JSON, JSON ↔ YAML, XML → JSON, CSV/JSON ↔ SQLite and OCR (extract text from images and PDFs).
22How do I zip or open ZIP and 7z files?
You can create ZIP, 7z and GZIP, unzip, preview the contents without extracting, and protect or remove the password.
View and open files
23Can I open a file without having the program installed?
Yes. In the “View or Open” category, you open PDF, image, audio, video, text, documents, spreadsheets and Office files (Word, Excel and PowerPoint) right in the browser.
