Frequently Asked Questions
Are my files uploaded to a server?↓
No. All conversion happens entirely in your browser using JavaScript. Your files never leave your device.
Is this service free?↓
Yes, completely free with no limits, no registration, and no watermarks.
Can I convert multiple files at once?↓
Yes. You can add as many files as you like and they will all be converted in parallel.
What quality are the output images?↓
PDF pages are rendered at 150 DPI by default (high quality). Image conversions are lossless where the format allows.
Is there a file size limit?↓
There is no hard limit set by us, but very large files may be slow since conversion runs in your browser's memory.
