Frequently asked questions
Are my files private?
Yes. Every tool here runs entirely inside your browser using JavaScript — your PDF and image files are never uploaded to a server.
Do these tools work offline?
Once the page has fully loaded, most tools continue to work without an internet connection.
Is there a file size limit?
There's no hard limit, but very large files depend on your device's available memory. Under 50 MB is comfortable on most devices.
Why did an encrypted PDF fail to open?
Password-protected PDFs need to be unlocked first. Use the Protect PDF tool's "remove protection" isn't listed — try opening the file in a PDF reader, removing the password there, then re-uploading.
